brake problems?

Question

I have a '01 nissan maxima w/ antilock brakes-4 wheel disc-I switched the rotors and pads in front now at high speed the car shakes and I cannot find the cause.The fluid is fine and I bled the whole system any suggestions?I also took the rotors back off to check to see if they were out of round but they are perfect-brand new-the pads are new also and the ceramic type spcified.

Answer 1

Try balancing you front wheels.
Does the car shake when you apply the brakes or wen driving at high speeds? By the way, what do you consider high speeds?
Lots of cars will shake if you hit say, 140MPH...

Answer 2

Lots of things can cause this problem.Balance is where you need to start. Balance your wheels,make sure when you put the wheels back on that you crisscross tighten your lug nuts. If you have vibration only when you hit the brakes, even new rotors can be out of specifications.

Answer 3

Have a loose caliper? You said the rotors are brand new and not just turned down so the hatch pattern is fine. Are your tires out of balance for some odd reason?

Answer 4

switching rotors (is it new)?without checking if its warp will cause this kind of problem. Your pad is not the problem. To find out if your rotors are warp is u can feel a pulsation in brake pedal when you apply brake esp. when slowing down. good luck .

Answer 5

Hi:

I have found that anti-lock will cause vibration under high speed applications; it is the result of the system balancing the pressure to all four wheels to avoid skidding. In other words your vibration may be normal under some operating circumstances.

Answer 6

did you spray the rotors off with brake clean after you got done?by you handling the rotors and pads,you probably got grease on them.

Answer 7

Check the alignment and thw wheels balance.
