Anyone else experiencing reoccuring warped rotors after installing ceramic brake pads?
My father did complete brake job w/"P-Boys" ceramic pads on 2 different trucks(Dodge Ram GMC Suburban)... first having the rotors turned... subsequently replacing rotors and drums after both vehicles developed pulsing pedal. After installing a second set of new rotors on the Dodge with no improvement, the ceramic pads were swapped out for the "usual" semi metalic on the GMC and the problem seems resolved on that vehicle. The Ram is scheduled for semi metalics this weekend to see if it provides the same solution. Currently with 2 weeks of service a runout gauge indicates 2 to 4 thou of runout on the new rotors. (too much?)
And yes he's aware of & goes thru the proper torquing sequence and doesn't over tighten the lugs.
We're under the opinion that the combination of a heavier vehicle with the ceramic pads cannot dissipate the heat as effectively and as a result...is repeatedly warping the rotors.
Is this Murphy's Law or anybody having similar problems?
