Prius (Gen 3) :: Rear Brakes Gone With Severe Uneven Wear At 55,000 Miles
Jan 20, 2013
While in for an oil change, the tech pointed out that my rear brakes were almost metal to metal, and that one pad on each side of the car had severe uneven wear. He noted he had never seen rear brakes go this quickly in a Prius and he had never seen the uneven wear. He said part of the mechanism that allows the pad to slide in and out as the brakes are used had frozen, creating a pivot point, and creating the uneven wear. The front brakes are fine with plenty of meat left.
Parts were ordered, including new shims and other hardware to try to insure this does not happen again, and the brakes were replaced. I contacted Toyota Customer Care and basically got the old line that brakes are a wear and tear item but the issue would be sent onto engineers.
I am the sole driver of the car and use the regen brakes at every opportunity, which is most stops. Since long brake life is one of the benefits of regen brakes, this is disappointing to say the least.

My 2014 Elantra Gt bought in May 2014 and 18000km on it now, the rear tires on both side are worn out pretty bad on the outter side of the tire. I took it to one of the dealer. The mechanic said that's not about the alignment, it's because I drove too hard in the corner..... So, I made an appointment with the other dealership which I bought the GT. I was told that it need the alignment and it's not covered by the warranty. I don't mind to pay for it but just want to make sure they will fix it.
I have the KYB on it right now. should I swap it back to the oem before I go to the dealer??

Have a 2001 F350 7.3 4X4 with single wheels in rear. Started hearing brakes noise and decided to change both front and rear pads. Front had almost half the pads left. Rear on drivers side had about half the pads left. The passenger side metal to metal on the inboard pad and about half the pad on the outboard side. The slides on the caliper were a little sluggish but moved freely. Don't think there is enough to have them turned so will have to replace the rotors. Why this would happen. Could the caliper get stuck? It was easy enough to compress with a C clamp.

The uneven wear occurred again, this time only giving me 22,644 miles on the rear brakes. So, I am on my third set of rear brakes at 78,000 miles.
This time the dealer contacted the district rep since this was a repeat occurrence. It turns out a week after my first rear brake job, Toyota issued T-SB-0248-12, for this very problem, on the 2010 - 2012 Prius and on the 2012 Prius PHV. There is a new brake pad that is supposed to address this problem. The old part number that was put on my car during the first brake job was 04466-76011 and the new part number is 04466-47080. The receipt also shows Brake Shim Grease part number 08887-80409, which is noted in the TSB.
Toyota did the right thing in that they covered the cost of the brake job I just had done. I just opened a case asking to be reimbursed for the first brake job since this turned out to be a problem that was addressed with a new part.
I suggest anyone with a 2010-2012 Prius or 2012 Prius PHV that needs rear brakes, make sure you insist on getting this updated pad and point out this TSB. My service adviser said they were going to replace all of their pads with the old part number with the updated pad, so other customers going forward receive this new pad, though he also said they just don't do a lot of Prius brake jobs.

I have a 2011 Camry SE which I leased brand new from a dealership in Ottawa. It has about 35,000 KMs on it. After my last regular maintenance at the dealership (32K oil/filter change with tire rotation etc.), I started noticing a sound coming from the tires. The sound is like low pitch boom boom boom boom. I tool it to the dealdership and they told me there is uneven wear on the tire which is normal for Camry SEs because they have wider tires that easily scallop during hard cornering.
Firstly, I do not buy that explanation because it's not the first car I have driven with a little wider tires. Secondly, I do not drive rough as most of the times I have my kids in the car with me. Lastly, I would think that if you are selling sports tuned cars, you would choose appropriate tires for it so buyers can drive it like a sports car.
I wonder why the situation became noticeable after the tire rotation. According to the rep at the dealership, all 4 tires have uneven wear so should I not have noticed it before the rotation?

2005 I4 SE Camry USA built. Got a squeak from the rears the other day and pulled the tires to check. Inside pads (ones against the caliper cylinder) on both rear wheels were at the metal but the outside pads were still not down to the little stripe down the middle of the pads, let alone the wear indicator clip. I pulled slide pins and there were not stuck. The calipers retracted very easily, so not gunked up or dragging. I ordered a new hardware kit with the new dust boots and rubber slide pin parts. I am using good Permatex disc brake grease. I am going to have to have the rotors turned, but aside from replacing the rubber parts the only other thing I can think of is slide pin replacement.

I just thought I'd mention this observed wear of brake pads...I just replaced all 4 up front after about 128k miles...
@ 114k miles it was observed that 1 of the 2 pads of each front wheel had worn significantly more than the other (the inner more than the outer pad IIRC)....my expert mechanic rotated the two and I got another 14k miles out of them...I could have gotten a LOT more had they been rotated @ 50-80k miles.
I don't know if this is extraordinary, or more typical than I'd have thought...or a function of (failing?) calipers, or just how these (MY) calipers work, or just my driving habits (though I've owned the car for only 30k of the 128k miles on the odometer)....but....
In my case the new pads will get a 50k mile inspection and possible rotation if there is uneven wear between outer and inner pads....
I'd recommend that pads be inspected for (uneven) wear at one of the scheduled tire rotations....rotating the pads isn't much of a job, but it might be something for you to consider to get the most miles from the pads (that and better braking too perhaps).

I have a 2006 SC 430 with 20,000 miles on it The (run flat) tires are wearing on the inside and the dealer says that they need replacing The local tire shop agrees, and will sell the tires to me for less, and also throw in an alignment He says that alignment is the reason for the uneven wear But the dealer says that the wheel on my 2006 SC 430 cannot be aligned, and that the new ones will probably wear the same way

I have a 1999 Ford Ranger XLT using the Futura GLS 225/70/R15 tires. The vehicle decal in the driver side door listed the recommended tire pressure to be 30 PSI. I have tried to maintain religiously along with proper balance and alignment. However, I've always had the experience of the tires wearing out more along the middle which seemed to indicate over inflation. The sections on either side of the center line seemed to wear out normally. For this reason I've had to turn in the tire prematurely as they become unsafe. These tires were made by Coopers Tire and distributed by Pep Boys. Have i been using poor quality tires all along? Do I need to lower my tire pressure below the 30 PSI recommended? If I do that wouldn't I be risking overheating and/or affecting my gas mileage?

I checked my pads today and noticed that the drivers pad is worn about 50% more than the passenger in the front. What could be the problem??

Any 1 have their tire that have uneven tire wear? Mines is Dunlop and my front right tire has uneven wear on the outer thread. All other tire don't have uneven wear. I'm getting new tire for all 4 rims and check my alignment. My gs is a f sport rwd.

I've had this "rattle" when going over uneven roads for about the past few months and I think I narrowed it down to the rear calipers. They are both tight, but it seems as though the "floating" ability of the caliper is loose.....does that make any sense? I mean you can grab the caliper and it'll make a rattling noise, but the bolts are tight..

My front driver's side Bridgestone Turanza EL400 (225/40R18) has premature wear such that the steel belt is beginning to show through the center of the tread. The front passenger side tire has no such wear and the alignment is good.

2000 Ranger, see my sig.
Just had to swap out the pads on my truck yesterday. The pedal was pretty mushy and I was getting shaking in the steering wheel when the brakes got warm. Shaking wasn't all the time, only after they had been used quite a bit - say after city use and the brakes had to be applied suddenly. So I popped off the tires and swapped out the pads and replaced the brake fluid - flushed it.
On the driver side front, the pads barely had any real wear and the anti-rattle clip was all messed up. It was installed properly, but it looked like the pads had smashed into it. The rotor appeared to be warped, or at least out of round - but just barely. You could see it wobble slightly in one spot if you spun the hub with the caliper removed. The caliper itself was sticking slightly.
I didn't see any evidence of damage, the brakes flushed just fine although the fluid was incredibly dirty (because I haven't done it in a long while). On the passenger side front, the pads were worn down to the level I would have expected given the mileage. The wear was even.
My question ultimately is this - is the out of round hub the culprit here? Might there be something else going on like a caliper problem? Ultimately I plan on having the rotors surfaced - one of them certainly needs it and with new pads I might as well do it anyway.

97 4.0 ext. As the title says the right front pads wear more than the drivers side. Have replaced calipers pads and rotors during recent overhaul. Noticed increased brake dust on wheel on rf front. Could the metering valve under master cyl be the culprit. Abs and brake lights work as normal.

Actually this started occurring at around 10k miles and I find it odd this would happen this early. It seems to happen more often on cold days and after a couple stops its gone. Why is this? I have heard of premature brake where on these cars and that braking power is biased towards the back under normal braking. I really do not how there is reduced brake dive using the brakes this way but its a vw. Is it just the stock pads that are bad?

So on my wives Prius which is an 2007 the rear tires are wearing more greatly on the insides that the outsides and they are wearing evenly on both the rear left and rear right inside. So not one is more worn than the other..
The tires are heavily worn, with that said the car rides extremely bumpy to the point the entire car is shaking on the freeway at 75 mph or higher. So much so it induces motion sickness which is odd for me. So also besides the alignment question, what else could be causing the insane amount of bumpiness? I balanced and rotated them yesterday but that didn't solve the issue.

Brought my car for an oil change at 42000 km (26000 mi) and asked the dealership to check my brakes since I've been hearing a noise for the last 2 weeks. Ended up having to replace both rear disks and pads. Dealer said everything was seized up and that they were able to rescue my front brakes by doing brakes service on them.
Next day, the exact same thing on my girlfriend's 2012 Accent..! Dealer told me that brakes need to be serviced every single year to avoid this...! Really??? I never heard of that before and needless to say, I didn't expect to get a 500$ + bill on a new car...
I checked with my mechanic and he did inspect my brakes at 24000 km (14900 mi) as I asked him and that everything was working perfectly.

I've noticed that from any higher speeds (over 100kmh) if the brakes are hit hard, they will suffer from severe fade and are useless until they cool for quite a while. Second, I don't know if it is simply my accent, but I just had the front pads done last year (they only have maybe 10 000km on them) and the brake pedal has probably 3/4"-1" of travel before any real stopping power kicks in. My parents just bought an 09 accent and the braking performance is just soo much better! I want to know if there is any way to bring my 02 accent on part with that of newer models. Do the calipers/rotors/etc from an 06+ model year will fit the 02?
I really have a sponge of a brake pedal and really want something done about it and I will go as far as it takes to get better performance out of my brakes.
