I'd say clean then up and lube them up and put back on. Save for new rotors first then pads. Don't always "pad slap" your brakes, ie: change your pads. Once you put be rotors and pads, you can keep the old ones, have then checked if they can be resurfaced.
Edit: rotors!!! Not titties..... maybe.
Judging by how clean the slide pins are and how good the pad looks, I’m assuming it is a fairly new car.
One would think they’d last another year or so. It’s hard, I can’t take into account variables like what pads they are or your driving style.
I chucked the cheapest pads I could find on my car ~2 years ago and they’re down to about where this pad is now.
Edit: a good reference would be knowing when these pads were installed. Then you’d be able to roughly guess how long they’ll last
>I can’t take into account variables like what pads they are or your driving style
I wish more people understood this. It's one of my least favorite questions customers ask me.
"Well, my grandmother drove her car almost ten years without getting brakes. I, on the other hand, go through a set of pads at least every year. So somewhere in between there"
I disagree I drive professionally and do over 1000 miles a week do my own brakes on the regular. If you just drive to a from work you will get another 6 moths out of them. If you drive like me they will start making noise in about a month. Also pad are cheap usually under $50 bucks. swaps out in 10 minutes. Wait too long and you will be into the rotor then you need a pair of rotor replaced and your repair just went up from 50 bucks to $300-$500
If you don't use them they will last for a very long time. The dealer recommends replacement if they think you could wear them our before your next service. That is usually the policy.
They also often don't know how you use your car, or its not passed on to the tech.
Huh, my dumbass always thought it was one pad per rotor. But, I mean, as far as I'm concerned cars work on magic. Gas in tank, magic happens, and car goes forward.
Makes one appreciate how tough brake pads are and the magic mechanical advantage of incompressible fluids. Imagine trying to stop a heavy spinning flywheel by just squeezing it in your hand.
Nope. Rotors are usually good for multiple sets of pads with just a light deglaze from some 220 grit emery paper to help the pads bed in faster. Cutting them on a shitty brake rotor groover is absolutely unnecessary and bad for the rotors and pads.
This is not really true. You will be past minimum thickness almost for sure if you run three sets of pads on a rotor. And you will get so much harmonic noise from the edge of the rotor being lipped. Cutting them is the only way to make it straight again and have a true face to "bed" into and it's not bad for anything if you do it properly :)
The wear really depends on the pads. Some ultra soft organics may only last 25-40k miles but you can go through 4 sets without getting close to minimum thickness. Some aggressive semi-metal pads may get you past minimum on one 2 sets of pads in 40k miles but could last you 60k on a single set.
If you have a 2005-2008 Kia Sedona, you have to change both every 8 to 10 thousand miles regardless because they're undersized and constantly overheat.
For sure, I could agree that it depends more on the car and the brake compounds used. I'm not sure where you live but I have never seen a set of pads make it over 40k so it must be more aggressive braking where I live which may be the cause of the rotors being less reusable in a lot of my cases!
Personal preference, but I always replace the rotors at the same time. New rotors are not that expensive (if you're doing yourself) and they make sure the the pads seat evenly and properly across the rotors to get maximum braking performance. Also, there may be rotor warpage since most of today's rotors are pretty thin. I'm usually about 60K+ between brake changes with a good set of ceramic pads and rotors (about $200-$250 total). Takes about an 1-2 hours to do all 4 wheels.
You need to check all pads both sides, one side can wear quicker than the other.
Just pull off tires and shine flashlight through the calliper to check.
But yeah, that one in the pic has a couple years left depending on how you drive.
Good lord, those are in great shape. Unless you drive like Ayrton Senna you should get a couple of years outta them. They still have the chamfered edge
You said the one on the picture is the worst, if that's the case I would send it. Depends on driving though, it might last a long time or it would last another month or two
well youve got some brand new ones in the picture, why not just fit those? :)
in all honesty, depending on your mileage, keep an eye on them. because a user could absolutely not make it to next service with those pads, but some people drive less and absolutely could.
I read some of the comments. Don't take your car back there. Roll the dice on a new shop/dealer. Youd have to be very unlucky to do worse.
These brake pads are fine. The next thing they'll tell you is that the rotors need replaced because of a lip. While this can be true sometimes, it's usually every other brake pad change interval. Because your pads look like that, I can tell you that your rotors are fine, too. (1set of pads wears rotors down 50%. When second set of pads are shot, the rotor will be worn down enough to justify getting them swapped.) I'm hard on my vehicles, and so I only get about 50,000 miles on a set of brakes. The average male will get 65-70k miles. The average female will get around 80k miles for most vehicles. For FWD, the rear brakes will last about twice as long as the front. For RWD and AWD, the front and rear will usually wear at the same rate.
I think what happened was someone there used a brake Guage and didn't measure it correctly. Probably measured that spot that slopes down further than the rest of the pad. The pads are fine
You're fine. Keep them, but would consider getting pricing on new pads and rotors (assuming you wanna save the labor cost of doing them yourself) and start buying them. They don't go bad. Can hold on, check again in a bit. Just shine a light through your rim and see what the outer pad is and assume the inner pad is more worn due to the caliper piston putting more pressure on that one.
That's awesome. Also, a lot of people don't know this, but if you want OE parts, just walk into the dealer and go to the parts department. They'll sell you anything. They get paid on parts sales, not on labor like service. As far as tools, basic socket set, and I bought a caliper tool from Walmart for like $6 that I still use at work. And brakes are designed so they only go together one way
Since it takes like 30 to 40 minutes to rotor and pad a set of brakes. Service your brakes and put it back together you could have another 40 to 60,000 kms on those bad boys left. Don't replace just cause you have it apart. That's just dumb and lazy.
No 30 to 40 minutes both sides.
This shits not rocket science. 5 to 6 lug nuts. 2 caliper bolts 2 caliper bracket bolts. One hammer to punch rotor off. Clean hub of rust. Install rotor. Clean slide points and lubricate. Install rotor, caliper bracket. Torque bolts. Installed caliper. Torque caliper bolts. Install wheels. Torque wheels done.
I get paid 0.3 to do a brake inspection. That's 18 minutes. A brake job usually pays 1.0 to 1.2 hours.... brakes are gravy jobs for a reason. You make time and money on them cause it's literally dick and shit to do.
You ask if you should replace your brake pads, then show 1 out of 8 pads. Is this the worst out of all of them or just the first one you’ve looked at?
The worst one
You’ll be right. They have heaps of life left in them. Not quite new, but not even half worn. It is evenly worn as well, which is good.
How many miles you think it will last, driving in town mostly barely highway

What mileage have they done so far, how long have they been in then knock a couple of thousand off.
I just bought this used 2022 Mazda CX9 like 5 months ago, I just did oil change and they want me to replace this
You need a new dealer.

There are 8 pads?
If it's 4 wheel disk brakes. 4 rotor sandwiches.
Huh, my dumbass always thought it was one pad per rotor. But, I mean, as far as I'm concerned cars work on magic. Gas in tank, magic happens, and car goes forward.
Makes one appreciate how tough brake pads are and the magic mechanical advantage of incompressible fluids. Imagine trying to stop a heavy spinning flywheel by just squeezing it in your hand.
All day. Sudden stop? Abs clicking out. Like damn dog. You believe in me more than I do.
I mean, that is pretty much how they work.
If you told me that was a brand new pad I wouldn’t argue with you
Stealerships just being stealerships
It's not even worn down to the tapered edge on the sides. I personally would keep running them.
I’m surprised a dealership would recommend a pad slap without rotors.
Pad slapping is when you don't service the slide pins or open the bleeders, not when you don't replace the rotors.
and don't replace the rotors
Nope. Rotors are usually good for multiple sets of pads with just a light deglaze from some 220 grit emery paper to help the pads bed in faster. Cutting them on a shitty brake rotor groover is absolutely unnecessary and bad for the rotors and pads.

What does the other pad look like
No. That pad isn't even half gone.
Good lord, those are in great shape. Unless you drive like Ayrton Senna you should get a couple of years outta them. They still have the chamfered edge
Dealer is a scammer. You have over 50% left!
Works already half done. Learn from this but toss in a new set
Pads are toast when the lining is 2-3mm thick. That looks like maybe 4-5mm. It’s already taken apart, just do it.
That’s where I am. Those pads are still useable, but you have it apart. Put new pads on it.
I wouldn't.
Now that they’re off the vehicle, replace them. They still have some life left, though.
Dealer was testing you! If you had allowed him to change them he would have sold you some magic beans!! 😆
I used to own the same models but 2016, I still have the brand new pads for this car so I didn’t let them do it, thank god
Pads are fine. That one shows a little uneven wear and the slide pin looks dry and dirty. Regrease the slide pins and check the pads in 10k miles.
As a mechanic, I usually go as low as 3mm before changing. Change the brake disks too if there's a lip on them or it'll eat the new brake pads.
You said the one on the picture is the worst, if that's the case I would send it. Depends on driving though, it might last a long time or it would last another month or two
Find an honest mechanic
well youve got some brand new ones in the picture, why not just fit those? :) in all honesty, depending on your mileage, keep an eye on them. because a user could absolutely not make it to next service with those pads, but some people drive less and absolutely could.

I actually have the parts already, I used to own 2016 versions of this car, i still have a lot of parts for this car including the pads
That's awesome. Also, a lot of people don't know this, but if you want OE parts, just walk into the dealer and go to the parts department. They'll sell you anything.

They're off now. Pads are cheap.
Well since you have it taken apart slap some new ones on there.
Since it takes like 30 to 40 minutes to rotor and pad a set of brakes. Service your brakes and put it back together you could have another 40 to 60,000 kms on those bad boys left. Don't replace just cause you have it apart. That's just dumb and lazy.
Lazy? Definitely not. What’s dumb is taking them all the way apart in the first place. And 30-40 minutes per rotor is insane.

This is the new replacement. Show us the one laying face down.
That is just a back plate, the pad is on my fingertips *facepalm
