Anyone ever have a powerslot rotor do this?
This is the inside face of the passenger front rotor on my DD 2001 Pontiac Grandprix. This rotor is a little over three years old. The car started shuddering like the rotors were warped, and when I tore it down this is what I found. The pad that runs on this face is about half as thick as all of the others too. Anyone know what might have caused this other than a faulty rotor?

I just replaced my brakes and they looked exactly the same, I was using iRotors slotted and drilled. My brakes were fading bad and warped. Since i got a misterious squeek I figured they needed to be replace. Fixed the fade, not the squeek its coming from somewhere else. Figures huh. Both my left and right calipers put more pressure on the piston side and it seems to wear through faster. Since they push on that side to the other. I am not sure how normal that is but I can see how it could be. If you used a hard metallic type pad as well against that, it would grind away over time. If it was a 4 piston brake you got I would be worried but I think you have a 2 piston on one side with teh GP's so its prolly not too far from normal. Does not mean its ok but I would think normal from wear from harder pads and hard quick braking. I had about 40xxx miles on my breaks even with 20's with 33" tires on the truck and they did ok. Surprised they lasted like they did.

Ya, I would agree with fry. Its not uncommon for the slides to stick. When you replace the pads do all the hardware too (the slides that come with them) and like fry said, lube up the pins and you shouldnt have that problem again.

How are the slider pins moving Tom? I've seen them sieze and create issues like that. I don't remember your rotors looking that bad when we pulled them apart last time to fix the squeak (how long ago was that?).
FWIW, my factory rotors rusted up like that, but the pad wear was even. I had the rotors replaced under warranty and those rusted up as well. I replaced those with some slotted rotors from Praise Dyno about 4 or 5 years ago and they've been fine ever since

The caliper pins where coated with never sieze when I did the first brake job, but the lower one was rusted, so it might very well have been sticking. I am planning to replace the rotors, pads, and all four pins.
You TX guys don't know what it is like to put vehicles through salt and snow, but I have been very dissappointed with how the Powerslots have weathered. I won't be putting another set on anything I own.

Don't feel bad, I put SSBC brakes on mine last year and they look like crap...and my truck is stored winters and hardly sees the rain! I wish I took the time to paint the rotor hats before I did them, I still might sand them down and do it this spring.

Oh yea, make sure that the caliper piston will depress, if not, it's siezed and you need a new caliper.
