Brake problems, I think

i noticed that my passenger rear rotor is only 1/8" think while all three of the others are at least 3/8" thick maybe more. is this normal? could that caliper be sticking?

I'd bet what you'll find is that the pads "ears" are corroded into the slots in the caliper bracket. Despite the SS slide "clips", all that stuff tends to weld together back there...

Take the two 12mm caliper bolts off and lift the caliper off so you can check those pins but, if they pull in & out 1/2" easily, try to slide the pads back off the rotor and see if they're not stuck there. You should never see uneven pad wear.

Either caliper sticking or the pads are catching in the sliders from rust and what not.

Have you noticed. Drop in mpg? Does that wheel ever get hot? Did you replace all rotors at once?

these are the original pads and rotors as the truck on has 70k on it. i have not noticed that wheel being hot but have not actually gone to it to feel. i will try to tear it down this week. i never thought about the pads sticking.
the rotor is getting thin enough that i am worried about it warping. any suggestions on rear brakes only or brakes all the way around? i think i am going to use EBC

I like to replace each axle as a pair

Tear your front apart also and just check to make sure its all moving freely and determine from there. If things are getting worn. And at 70k in sure they are. If you got the money is just replace atleast rotors and pads all the way around calipers dont normally go bad that often

Yea, I'd be surprised if your, 70K, rear rotors are any good. It's gonna be more about corrosion than any "thinness" (these rotors don't really warp anyway, pulsations are caused by surface differences). Because the backing plate keeps it damp, it rusts, those rear pads don't get the workout the fronts do, and that rust gets deposited on the pads and ground back in. The back sides of those rotors get really lumped-up.

Good news is, they're cheap! I mean, the way they probably are right now, they're barely doin' their job. Your fronts are the real brakes anyway, I don't think twice about buying cheap stuff for the rears and spend the money you save on really good brakes up Front

I see eBay kits (rotors/pads/clips) for $100 delivered!

I wouldn't necessarily think you need to do the fronts now, check 'em and see. I would spend for the "good stuff" up there though (cryo/hawk/new pins).
