Ceramic brakes squeal
Posted on 2014-09-20
I have a 2001 Trans-am that I wanted to put new ceramic brakes and drilled amd slotted rotors on but the problem I am having is that when I replace the brakes with new ceramic brakepads they squeal whether I am on the brakes or not. The only time the car doesn't squeal is when I use the original factory rotors and new semi-metallic brake pads. This is the variations that I have tried but, the brakes always squeal. Have only tried replacing the front brakes. I don't even want to trink about trying the back until I get the front worked out.
I also tried the brake quiet stuff that goes on the back of the pads but, that didn't help either.
1. New drilled and slotted rotors with new ceramic brake pads - squeal
2. New drilled and slotted rotors with old brake pads - squeal
3. Factory rotors with new ceramic brake pads - squeal
They are prostop rotors and pads from Summit racing. I also tried platinum ceramic brakes from Advance Auto wi the same squeal results as the 3 listed above.
I bought a set of cheap ($21) semi-metallic pads from Advance Auto and used the factory rotors and they don't squeal at all but, the brake dust is horrible.
Does anyone have any idea why this is happening with ceramic brakes. And the original brake pads I took off were the factory original, Seriously they were. There is only 21k miles on the car.
