Rear Pads Worn Out Long Before Fronts - Anyone Have A Similar Experience? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So I'm approaching 37k on my 2013 V6 and the rear pads just hit the wear indicators and started squeaking. I checked all 4 wheels. The fronts still have another 1/8" of pad thickness until they hit the squealers. Both rears have the squealers just starting to touch the rotors. This will be the first time any of the pads have been replaced. What would cause the rears to wear faster? I know they're usually thinner to begin with, but with the fronts doing most of the work, how could this happen?

I've never driven with the parking brake engaged. The brakes don't drag (to my knowledge). I don't ride the brakes, rarely drive in stop-and-go traffic, etc. The only thing I could think is maybe something to do with drag racing? They are all the stock pads, and I've made probably two dozen 1/4mi passes in the last 2 seasons. Still seems strange that the fronts aren't showing more wear though. All rotors just have normal wear, with fronts and rears being equally smooth/rough.

Any ideas?

My SS the front pads wore out before the rears.

The parking brake doesn't use the pads anyway, there's actually a tiny drum brake inside the rear rotors which is the parking brake.

I'm nearing 80K and still have not hit the squealers.... looks like I could possibly get another 20k out of them but I won't wait that long.

My rear pads will last about 2x as long as the front. 48k and some change on the rears and they still have about 20k of life left in them. Fronts made it to around 37k. Replaced with OEM pads.

First off - your traction control system uses the rears for most corrections if you're running into traction control limits often.

Second - A higher rear-bias on braking means the car stays more level during deceleration. It's becoming more common-place for manufacturers to do this because it adds a premium feel, and greatly reduces nose-dive. Luxo cars do that often. I currently work at BMW and more often than not the rears wear out at the same time as the fronts.

Very interesting. Did not know this.

I should drive harder apparently.

The cops don't like that much around here.

I hate this town and most of this state for that matter.
