Question Uneven rear brake pad wear

First off I'm not sure if this should be here or in the drivetrain forum, so if the mods want they can just move it for me...

Anyway, I replaced my rear pads today and the outer pads were worn about twice as much as the inners. Is this normal, or is something F-ed up? Also if you look at the profile of the pad from the side, its worn on an angle. WTF is up?

Also my rears wear out about twice as fast as my fronts, could this be from my frequent burnouts at the track or is something screwed up?

It always stops good, and the e-brake works fine, just curious if I'm over paranoid or there's an issue here?

I did my rear pads 2 weekends ago and the outer pads were worn a lil more then the inner's... Might be a common thing...

They should wear evenly. Your caliper brackets or pistons may be sticky. It is normal for the backs to wear out before the fronts on these cars (sometimes almost 2 to 1).

Ya I've always heard even as well

Shoebox- What about durm brakes, I've never seen a pair that was even, not sure if this is normal or from people not using new hardware, or sticking wheel cylinders/brake cylinders?

Notice, I said should.

Ours is not a perfect world and the world of drum brakes is even more imperfect. Even wear is usually attempted through the use of different size shoes foreward and rearward of the axle, because wear characteristics are different for them. Even then it does always work as intended.

I dunno... My stock rotors did have 85k on them... Maybe that had something to do with it... New rear pads and rotors and greased up the pins, cleaned it all up good.. We'll see how it lookin in 20k-30k

Checking and greasing or replacing (if needed) the caliper guide pins could help. As far as the piston goes, you would need to buy a caliper rebuild kit (cheap), pop the piston out, clean things up and check for evidence of any corrosion, binding, gunky fluid, etc. Replace seals with what is in the kit, reassemble and bleed the brakes when done. The only other option is to replace the caliper assembly with a new one.

I bought a rebuilt caliper from Pep Boys for 17.95 plus tax & 20.00 core return, to me that was very cheap. I don't know how much a rebuild kit would cost, and, $18 bucks for a rebuilt caliper was a great price to me.
