Brake Question (looked at FAQ already)

this question didnt seem answered

Will I do fine with old calipers and nice new slotted rotors and good pads

i just ordered brembo's like 20 minutes ago, just wondering if they will warp because of the calipers?

its always recommended to get new pads when using new rotors. using old calipers should be fine as it doesnt directly make contact with your rotors.

Thatís an interesting point you bring up. If I understand you correctly: the rotors are notorious for warping. My first Jeep, in 1988, had rotors that warped. So the question is: during the last 16 years, does jeep and aftermarket people supply crap for rotors or is it crappy calipers? I have heard of dual piston calipers, for the jeep-fix. Maybe these distribute the pressure more evenly to prevent localized hot spots? But then why do other single piston calipers seem to work well with other vehicles? Maybe someone can shed some light on why this flaw has been around for so long

Cheers Steve

I had a 1988 Cherokee for almost 10 years that never had a rotor problem. I had my 99 GC at the dealer for recall work and allowed them to turn all 4 rotors and new oem pads. 7,000 miles later I have pulsation in the brakes. I have read other post that oem rotors are a different material to reduce cost. Jeep issued a TSB about the calipers and updated replacements, so they must have concluded that there is the potential for a problem. I'm planning on replacing the rotors with standard rotors (non slotted or drilled) from local autoparts store with new semi-metallic pads. I think it is important to also check that the calipers are functioning properly. I think there is a slide pin that is suppose to be lubricated with caliper grease.
