rotor recomendation

Hello,

1989 v2500

I finished a complete front end rebuild with and now i have a brake shimmy. I bought raybestos rotors and centric pads and they vibrated from day one. I have switch the pads to an organic and it is getting better but i could never get the semi-metalic to break in right.

Anyway, I am also suspicious of the rotors, the casting flash on them looks crappy and for what is cost to turn a set I am thinking of just buying different ones.

any recommendations or what to stay away from?

Chris

Re: rotor recomendation

When you pressed on the rotors, did you have them trued up?

I have checked the run out of the rotors and the hubs, they are both within a few thousand. I think it is more about the composition of the metal and how the pad bedded.

Re: rotor recomendation

Finish on the rotors may have been too coarse. May have to wait a day or so for them to polish out

Re: rotor recomendation

All of the local repair shops use Centric brake parts now. I had them installed on my 2002 Cavalier, front and rear, and the front rotors and pads are fine, but the rear drums were out of round, causing the rear brakes to pulsate. Someday I will change over to Delco parts and be done with it.

Scotty Kilmer recommends Akebono pads but I have never used them. I would do some research on Akebono and see what you find out. Given the massive size of 3/4 ton truck rotors, I think it is more likely that you have some other problem. Are the calipers sticking?

I had a local brake shop put Raybestos rotors and pads on the front of my 83 C20 and they have been working fine for about the past 14 years and 45k miles, almost all city driving. I think it is possible that you have just come up with the periodic bad rotors and/or pads that most manufacturers produce.
