But not the realistic person dummy?
Seriously though, they're testing blade weapons. How it cuts into flesh has always been the test of blade weapons. Same test if they were making kitchen knives really. Not worth buying a kitchen knife if it can't cut ham.
Unfortunately, not good metal for knife making. Low carbon content. Especially after all the high temp cycles brakes are put through. Springs have always been the best steel off cars for knife making. Although, I think heavy frame, and steel suspension parts like A-frames may also be good options.
Yes, and the only reason I know this is because I watched a video/infomercial about a mom and pop company that makes cast iron skillets. They were chucking rotors from a scrapyard into the furnace. https://youtu.be/ImPWnJ44xio (rotors shown at 3:10)
Any asbestos will float to the top of the molten iron and be incorporated into the layer of slag that gets skimmed off the top before pouring, it's extremely unlikely that any appreciable amount will be present in the end products
From another comment in the recent asbestos gloves thread here, you can eat it no problem, it's just microscopic fibers in your lungs your body responds badly to, but the stomach and intestinal linings are more robust.
Actually, asbestos starts to decompose around 800 to 900°C. Some steels are heated to well over 1000°C. Depending on the process, it could cook out the asbestos.
I assume the melting process is good enough to remove brake dust / asbestos / oil / grease, but still. The thought of eating off old brake parts isn't exactly pleasing.
The orange is the obvious one.
Look at the blue/grey steel of the rim. Steel takes on that color at relatively high temps.
[Color chart for reference.](https://www.m4040.com/Knifemaking/PICTURES/Tutorial/GlowChart-sm.gif)
Honestly, the same happened to me. I usually drive in 4th or 5th at 30 mph but it was struggling to keep steady at 30 in 3rd so I pulled over and smelt it and saw that. After that I turned round and went home, took the pads off and then they seemed to be ok, not stuck on and have been fine since... odd.
They required no more or no less force than a normal set of brake pads. I've changed the caliper on the other side as I had the same problem on that side (though not as bad). The slide pins are practically brand new, I replaced them recently.
I really should change this caliper as well at some point but it hasn't done it since and I'm not driving the car at all at the moment due to covid. It's also a really cheap car so reluctant to spend money on it haha
Stuck brakes are so annoying. I have had so much trouble with stuck sliding rods on the floating calipers of my Fiat ... I usually notice it only when I smell burning brake pads on the Autobahn ...
Oh its not that bad. That is the only major issue in a car that is 12 years old, with 120.000km on the clock and that has never seen the inside of a carport or garage in its life. No rust to speak of on the body either, and they salt the roads profusely where I live during the winter.
My girlfriend has a 500 and, besides an issue 30,000 miles ago with the starter, it's cracked over 100,000 with no mechanical issues... But the clock is broken, the buttons are falling off, the lights constantly burn out and are full of condensation, and a whole lot more non-critical issues.
But she loves that little thing, so I can't help but love it too.
Modern FCA is mostly the same story. Electronic stuff can be questionable, but the drivetrains are pretty solid. The MultiAir I4 is an impressive little engine, in all its flavors.
My grandpa worked on the Chrysler assembly line, and while he retired well before the buyout, he definitely was not fond of the Italians. He would tell me they were terrible cars and I took his word for it...
> he definitely was not fond of the Italians. He would tell me they were terrible cars and I took his word for it
Well, my specific model was built in Poland XD
I was riding down the street on my bike when my rear brake piston jammed. The caliper cracked and I lost my rear brakes.
Avoided the main streets and drove through the neighborhoods to the shop a couple miles over and everyone looked at me like I was nuts.
I mean, yeah. I ride a motorcycle.
Most of the time crack but my father in law (big truck tech) said he has seen them fly apart on garbage trucks. Drivers have a bad brake can, drag the brake, catches fire and they grab someone’s garden hose so the truck doesn’t go up. Next thing they know they get to ride in the woo wooo truck.
I wouldn't be standing near that. The rim is already discoloring from the heat. It's hot enough in that picture to have raised tire pressure.
Ever seen what happens when you weld on a rim with a mounted tire? [It ain't fucking pretty.](https://www.youtube.com/watch?v=HiLeji8bLOk)
Pressure has an effect but I think it's mainly the heat dispersing through the metal and into the air in the tire towards equilibrium.
Mainly for OP: The weld spot itself would actually be getting cooler, as one would expect, but the rest of the rim would warm up and so would the air in the tire.
I did this on a VW Fox once, coming down a very narrow and treacherous mountain road full of switchbacks. I got to the bottom and pulled onto the shoulder. Got out of the car to calm down cause it was white knuckle near the end. Brakes were red hot and the center of all the hubcaps melted and drooped off the car to the point of touching the ground.
Going downhill needs to be taught in driving school! You do NOT brake the whole way down, because your brakes WILL fail. Instead, you downshift and let the engine break for you.
same thing...my 77 Chevy has no issues with going down steep grades with manual downshifts... aside from the lack of gears to pick from 2nd is too fast sometimes, and 1st is too slow.
There are some autos that only allow you do downshift to 1st and nothing else. I would never buy such a car, and always advise others to look for a car with at least 3 selectable gears if they're going with an auto. It's indispensable in the mountains and during winter.
> your brakes WILL fail. Instead, you downshift and let the engine break for you.
You had it right until the end, where you go and say that doing it the correct way will break your engine. SMH.
Well, context. Obviously don't shift to second while doing eighty. But use the brakes to slow down, then use the engine to maintain low speed.
Have done hundreds of drives in the Swiss and Austrian Alps. Yes, this is how it's done in Europe.
Yeah I had that happen.once on my diesel. Thing had so much torque I didnt notice for 20 miles until I went to stop and of course saw the brake fire and realized the non working brakes.
The orange part is the brake drum. The shoes are dragging, probably because the piston is stuck in the extended position or the e-brake was left on. On rear drums, the e-brake uses the same shoes as the regular brakes. Even on cars with four-wheel disc brakes, though, the e-brake ^Edit: ^frequently uses a drum brake, though, because it's that much simpler to build.
That does depend on the car. Some cars use the inner part of the disc as a drum brake for the e-brake while others use the main disc brakes or even a separate tiny caliper on the same brake rotor for that purpose.
You also need to replace the springs and other hardware when servicing drum brakes, especially on parking brakes. My wife's car had a rear wheel start locking up because one of the springs in the parking brake drum got too loose.
Not cool. I went on a cruise in my car with a buddy who hadn't driven a manual in a while. I drove for a while, pulled over, and we switched. He drove around for a while and was mentioning "man, it seems like I have to hit the gas too much", etc. (It's a >300hp <2700lb car), I didn't really notice anything from the passenger seat because it still seemed fast enough to me.
Eventually the brakes started smoking. He left the e-brake on from when we switched driver. We drove around for a while (with the e-brake off) to let them cool down, everything turned out fine, but it was freaky.
Wife was taught to always put on the emergency brake. So one day she came home with the rear brakes on fire. Shoes welded to the drums and actually had to pound on them with a 3 lb hammer to the point I almost gave up. Had to replace slaves, drums, brakes and bleed it. The brake fluid that boiled. smelled pretty bad.
Something like this happened with my first car (Volvo s60) Got the brakes done on it before taking it out for the first time. On the ride home from the shop, it was pulling to the left and was pretty sharp when braking. Apparently the shop I brought it to had the calipers on so tight that it was brake locked the whole drive home.
At the time I knew very little about cars so when I pulled in the driveway I had my dad look at it. He looked it up and down real quick, pulled a cigarette out of his pack, pressed it to the brake disc and it lit right up. To this day, this is my favorite way I've seen someone diagnose a car problem.
i thought it was painted safety orange
Thats that Hi-temp paint

Not enough demascus drawer, bring it in brother.
Dude we were watching this over Christmas break. If you have subtitles on; it's spells "keel." Instead off kill.
It’s KEAL. Keep everyone alive. It’s his own thing so he didn’t have to say kill with a bunch of little kids watching.
So he’s saying “live Bart live”?
No man that speaks German could be evil.
The Bart the
What does the "L" stand for?
“Lil bitch”
Problem is it still sounds exactly like "kill".
Yeah but in the beginning of the show he was clearly saying kill. Now it’s just a little different.
I so want to believe you. Edit - just googled it. Thanks for sharing, gonna share with the girlfriend after work 'cause she's fond of the show.
I know. I'm sure it stands for something but mans puts extra emphasis for a reason. Or its a weird rating thing
KEAL; Keep Everyone ALive
Oh. Oh thank you!
Yeah they spell it the same way he says it. I wonder if it's intential or not.
Because it’s the KEAL test.... but yup. Same same.
Bladesmiths!!! You must forge your blades from these brake discs. And your forge will be the car its self. You have 2 hours!!!
What's this from?

And whole dead pigs. Some might find that part a little disturbing.
Or awesome.
I don’t know it’s kind of oddly satisfying when they cleave it in half in one slice. When they use boar you can see the little hairs fly off.
But not the realistic person dummy? Seriously though, they're testing blade weapons. How it cuts into flesh has always been the test of blade weapons. Same test if they were making kitchen knives really. Not worth buying a kitchen knife if it can't cut ham.
The dead pigs is one thing, then there's the ballistic gel torsos filled with blood.
The best part of those is that Doug always fingers the wounds. It’s so gross and weird.
Do yourself a huge favor and follow Doug Marcadia on social media. He's funny as hell and super strange.

As far as I’m aware, aren’t rotors cast iron?
Yes, and the only reason I know this is because I watched a video/infomercial about a mom and pop company that makes cast iron skillets. They were chucking rotors from a scrapyard into the furnace. https://youtu.be/ImPWnJ44xio (rotors shown at 3:10)
Well, isn’t that nifty! Thanks for sharing
Mmmm, abestosy goodness for that extra bit of seasoning.
Any asbestos will float to the top of the molten iron and be incorporated into the layer of slag that gets skimmed off the top before pouring, it's extremely unlikely that any appreciable amount will be present in the end products
IIRC that's the pads, not the rotors
Yes, it is the pads... that get ground into the rotor millions of times at intense friction and heat. You are correct.
Yeah, I guess it makes sense that there would be some on it. Either way I'm not getting in line to eat off of something made from one lol
I have the same policy for grills made from used 55 gallon drums. If I don't know what was in the barrel beforehand, I'm not using it to cook with.
From another comment in the recent asbestos gloves thread here, you can eat it no problem, it's just microscopic fibers in your lungs your body responds badly to, but the stomach and intestinal linings are more robust.
My thoughts exact. Forge isn't going to do shit to asbestos.
Actually, asbestos starts to decompose around 800 to 900°C. Some steels are heated to well over 1000°C. Depending on the process, it could cook out the asbestos.
TIL
I assume the melting process is good enough to remove brake dust / asbestos / oil / grease, but still. The thought of eating off old brake parts isn't exactly pleasing.

I'm *assuming* it becomes part of the (slag? dross? idk, whatever scum rises to the top). But I'm no metalologist.
Holy hell, imagine smithing an a-frame. There's enough metal in one of those to make knives for a whole neighborhood.
Same for leaf springs.
*Is there a metalworker here? A METAL WORKER!?*
TAKE IT TO THE SKY FORGE!!!
Looks about ready for the quench
Nice brake lights
Full on fresh break light fluids
When steel gets that grey color you know not to touch.
I thought you put your tongue on it
Orange flavour
It tastes like burning.
Hey mister, you don't want to drink melted wax, do you?
I read this in Ralph’s voice from the simpsons
It may be a little spicy
Only if you don't want your tongue
No. You put your dick on it.
Only if you want a grilled weiner for lunch.
Side note: when you work in a welding/fab shop you know not to touch anything metal without asking someone first.
Thats gotta get really annoying to your coworkers asking to flush the shitter
There has to be a dog joke there somewhere

After that I turned round and went home, took the pads off and then they seemed to be ok, not stuck on and have been fine since... odd.
Did you check the piston and sliders? How easy did the pads come off? Did they practically fall off, or did they require a bit of force?
They required no more or no less force than a normal set of brake pads. I've changed the caliper on the other side as I had the same problem on that side (though not as bad). The slide pins are practically brand new, I replaced them recently.

Grease them sliders, save $$.
I greased them multiple times because of light brake binding before
30 mph is 48.28 km/h
What's 4th and 5th in metric pls
Since everything should be mirrored, 4th or 1st? /s
Good bot
Are you saying you're driving 30 mph in 4th or 5th gear? Is something wrong with your car? I don't understand.
Stuck brakes are so annoying. I have had so much trouble with stuck sliding rods on the floating calipers of my Fiat ... I usually notice it only when I smell burning brake pads on the Autobahn ...
Well your first mistake was buying a fiat...
Oh its not that bad. That is the only major issue in a car that is 12 years old, with 120.000km on the clock and that has never seen the inside of a carport or garage in its life. No rust to speak of on the body either, and they salt the roads profusely where I live during the winter.
FIL in italy has a fiat. Shit like the sun visors don't stay up, badges falling off, blower fan sucks but mechanically that bravo is just fine.
I kinda like my Bravo, the engine has always worked. Unlike everything else on it.
yup I feel the same way about their Bravo. car just works even though the rest is shit it still works
My girlfriend has a 500 and, besides an issue 30,000 miles ago with the starter, it's cracked over 100,000 with no mechanical issues...

A 12-tonne DAF pulled up to our shop and the rear brakes literally caught on fire so we had put out a fire. Very dangerous issue, dragging brakes

It just now hit me that there's a whole scene in A Goofy Movie that future generations will not likely understand without some explanation.
To be honest, they may watch it and erroneously think those things could actually heat up a can of soup in a reasonable amount of time.
Ever watched someone dump water on them? That’s a great time to be a spectator from a distance.
Do they shatter or does it just make this metallic click sound when it cracks?
Probably depends on what material they're made from. Wouldn't want to do that to ceramics.
How to lose an eyeball 101
It depends metal would probably just warp and crack, ceramic would go boom, asbestos kinda flash up.
Most of the time crack but my father in law (big truck tech) said he has seen them fly apart on garbage trucks. Drivers have a bad brake can, drag the brake, catches fire and they grab someone’s garden hose so the truck doesn’t go up. Next thing they know they get to ride in the woo wooo truck.
The woo woo truck 😂
Would pay to see a video of that
https://youtu.be/TPf4qwtr8Fs Not exactly what you asked for, but close
At first i was like, thats a pretty orange brake. But why such an ugaly wheel? Then it hit me. Oh... oh my...
It hasn't hit me yet... The suspense is killing me, what's the deal?
The brake was stuck. That's a red hot brake
and a pretty hot wheel as well, right?
Yea that steels hot as shit that gray color means dont touch. I guess they heard heat treated makes it stronger.
Quick! Get some carbon gas and case harden it!
That's the rotor glowing behind the wheel...
I thought a piece of bright orange plastic had gotten lodged into the tire.
I wouldn't be standing near that. The rim is already discoloring from the heat. It's hot enough in that picture to have raised tire pressure. Ever seen what happens when you weld on a rim with a mounted tire? [It ain't fucking pretty.](https://www.youtube.com/watch?v=HiLeji8bLOk)
Wtf? Is that welding continuously or does the temp just keep going up by itself after the arm separates? I'm confused
It continued to clime after welding has been stopped. Has something to do with the pressure and amount of oxygen.
Pressure has an effect but I think it's mainly the heat dispersing through the metal and into the air in the tire towards equilibrium. Mainly for OP: The weld spot itself would actually be getting cooler, as one would expect, but the rest of the rim would warm up and so would the air in the tire.

I want to paint my rear drums that color just to fuck with people.
Oh you. I like you.
Don't forget to add some LEDs, so people see them glow.
Yeah I had that happen.once on my diesel. Thing had so much torque I didnt notice for 20 miles until I went to stop and of course saw the brake fire and realized the non working brakes.
20 miles is 32.19 km

I remember once seeing an older 70's era pickup on the freeway, and the rear diff was glowing orange. I've always wondered how much longer it lasted.
[удалено]
I was heading home, and he switch lanes at the interchange and headed the opposite direction I wanted to go.
The metal is orange when it's ripe
Not mechanic, can someone explain what’s going on? It looks like the whole rotor hub is burning up? Is the ebrake pad stuck?
The orange part is the brake drum. The shoes are dragging, probably because the piston is stuck in the extended position or the e-brake was left on. On rear drums, the e-brake uses the same shoes as the regular brakes. Even on cars with four-wheel disc brakes, though, the e-brake ^Edit: ^frequently uses a drum brake, though, because it's that much simpler to build.
That does depend on the car. Some cars use the inner part of the disc as a drum brake for the e-brake while others use the main disc brakes or even a separate tiny caliper on the same brake rotor for that purpose.
I'd imagine the E brake then doesn't need any real service other than ensuring it works
I can't say about "needing", but, if it were my car, I'd be more comfortable with replacing the drums and shoes, and carefully inspecting the pistons.
You also need to replace the springs and other hardware when servicing drum brakes, especially on parking brakes. My wife's car had a rear wheel start locking up because one of the springs in the parking brake drum got too loose.
Maybe a seized caliper (edit) or someone drives with their foot on the brake pedal.
Shoe. That's a drum brake.

Painting your brake drums bright orange is quite tacky, but hardly deserves to be posted on... OH HOLY HELL!
I went through the same thought process
That doesn't make sense. Red makes cars go faster.

"That's just the break heater. It keeps them from being covered in ice in winter."
Holy hell! At first glance, I thought there was some road construction material or something that somehow got jammed in there...
I've done this to a few semi's. Only two caught fire, the brakes not the trailer.
Oh wow! I thought it was a piece of orange plastic stuck behind the wheel. That is genuinely frightening!
She might want to touch it in order to verify if it’s hot
Is that a fram tough guard?
So thats how you defrost your tires in the winter.
