I am looking at replacing my F/R pads and while I was looking at my rear rotors they look like SH!T...........:( ........really worn on the inside of the rotor, especially the drivers side rear rotor........

I have 58K miles and 3 winters on the original brakes...........front rotors look salvageable, rears do not look like they will be........and I have noticed a decline in the stopping distance of the truck.

I assume the rear rotors are the 4.63" sized center hole..........are the GM OEM components good or should I look at BREMBO or RAYBESTOS or one of the other aftermarket companies.......

Also I am reading about Ceramic Brake Pads........good, bad ..........what ???????

Any help is appreciated, I need to order parts so I can get them changed out this week...........

Thanks.....

:cool:

Antwan...whoops, I mean Tony ):h

You're probably going to find your inside pad is worn out on your rear brakes..pretty common problem...
Should be 4.84 center hole...the 4.63 center hole units were used on the 10.5" rear axle trucks, the 4.84 used on the 11.5" axle trucks.
I would put ceramic back on your truck (that's what it came with) The reason I say this is because they produce almost zero brake dust, they're quiet, and they last for quite some time...
When the time comes, I'm going to try a set of the drilled and slotted rotors from work to see if there's any difference..mainly because I can get the pretty cheap :)
Also, make sure you don't get cheap rotors (read: Chinese or Taiwan) you'll warp them instantly

Make sure you lubricate the pad contact area on the pad holders with high temp silicon grease. You may want to pull the pads a couple times a year and do this. The pads end up binding and do not clean the rotors off properly causing the problem you have.

One possible reason for your rear rotors looking bad may be because of rocks getting caught between the rotor and the caliper. If you look closely you will notice that with the caliper being on the "front" side of the rotor, it creates a natural trap for small rocks etc. The rotor is also turning into the caliper, thereby helping to "push" the rock in place. Some other brake designs keep the caliper on the back side of the rotor so that if a rock does manage to get in there, the rotor is turning in a direction that helps "pull" the rock out. Unfortunately GM decided to position the caliper on the "front" side of the rotor. The only thing GM offers to alleviate this problem is caliper guards and the special rubber mudflap type guards for the inside of your rear wheelwells. (just forward of your wheel). Well worth it! I have installed them on mine and have had no problems with the rear brakes. Good luck!!:)
