Uneven Brake Pad Wear

[PatrickIvan]

I know, they're dirty. They're really not like this often.


I'm certain these brake pads need to be replaced. Those inside ones barely have 4mm on them. And I'm guessing that either a complete caliper service or replacement is probably in order.


And probably the rotors as well.

But what would cause such uneven wear so quickly over 4000km of very moderate use? I'm not a heavy braker, or heavy stop and go driver. I'm pretty moderate. I've gone a couple of very modest and short trails only 3 times. Since getting this Jeep in October.

I just can't see how I could have caused this kind of wear in such a short period of time.

I mean, I'm presuming the official Chrysler Dodge Jeep dealer serviced it before selling it to me. They said they did. So it had to be me, right?


Don't get me wrong. If this is me, I have no issues paying to fix what I use. But if it isn't my fault...

I guess I'm just venting and a little pissed.

The wheels are just the OEM 255s on the JLU. Probably would have looked better if I cleaned them before I took the pics.

4000km or 40000km? The rotors look like hell. My guess is the slides and pins need to be greased more often, I'd buy new everything and see what happens.

Yup... 4,000 km...

I'm guessing they didn't even take the wheels off to check it before selling it to me. They said the original owner bought it there, and it was serviced it's full 4 years there before I bought it.

I was in a rush and depressed after being in an accident. I didn't want to car shop at all. But saw this and I superficially instantly liked it. But it was an impulse buy for sure.

Don't get me wrong, I like my Jeep! I just don't like being hosed.

In the mean time, I did grease the slide pins. They weren't springing out properly.

I would consider replacing those rotors as well as the pads. They are pretty crusty, and the retaining bolt for the rotor looks like it will cause cuss words, so plan on drilling it out at the same time.

I see a need for new rotors, pads and calipers x2...or x4, depending on the condition of the same components on the other end of the vehicle. A fluid evacuation and refill would be the bow on this package, too.

I think I'd agree with doing all 4 when I do them.

I'm just not happy with it considering what I paid.

So you say previous owner. How many KM tota does the Jeep have because obviously those are original if theybare that busted up.

If you didn't call it out when you bought it you're most likely SOL at the dealership unless you have a good relationship with them already.

Dude, it's the dirt. Clean everything, turn the rotors, replace the pads.

Dirt didn't cause 4 mm of wear on the inside pads over 4500 km or 99.07% of paved road driving...

I clean my Jeep after the whopping grand total of 10km of unmaintained road I've take it on since buying it in October. I haven't had the time to take it anywhere fun yet.


That's my issue I'm having with the dealership. They're saying they checked it presale and the rear pads had 7mm.

And the outboard ones indeed have 7mm.

My contention is that they either didn't check the inboard pads, or there was some insane failure of the callipers that caused 4mm to wear on the inboard pads, and I somehow had no idea.

And there's no way that 4mm of pads wore down in 4500 km without there being some obvious indication. Plus, the odds of the callipers buggering up just after the sale would be pretty coincidental.

But I 100% agree that the pads need to be changed. New rotors, and pads, and hardware isn't that expensive and is an easy job.

I just think the Chrysler/Dodge/Jeep dealer should pay for it.

Normal wear, It doesn't pay to turn rotors anymore. replace rotors, and pads. Don't over think it.

Yes, the rotors are more than likely normal wear. But they should have been replaced before selling the vehicle.

And again, it is absolutely NOT normal for one brake to wear at twice the rate of another. That's typically indicative of a calliper related issue.

And if that was the case, it should have been identified during the presale inspection. Not passed off as a repair for the new owner one season later.

When you R2 the pads and rotors use ample lube on the caliper pins and pad to shim interface; this should help with the uneven wear. That said, just by sake to where these parts live, that will only last so long depending on how you use your Jeep.

In a perfect world yes. Unfortunately in our world it happens every day. Unless the vehicle has to be state inspected before the sale it all depends on the reputation of the seller. As far as even wear on break pads not so. Heavy breaking, hard turns all contribute to pad wear. But enough said. Good luck with your project.

Why should they pay for it? There is no warranty on brakes at all, especially on a used vehicle. Do you or do you not own this vehicle?

We turn rotors every single day. 15 minutes of work or $100+ for a rotor. No brainer.
