Yeah ive noticed when im doing well over 70mph and i start lightly pumping the brakes my car shakes big time.Is this because i probally need brake pads? I dont kno but im tring to sell my car and dont want that to happen to the next owner.thanx

Does it do it anytime you hit the brakes, or just at highway speeds and pumping the brakes?

Also, put your year and trim level in your sig so we can have a better idea of whats what here.

its a 96 bonne se, i dont kno the trim.It happens only when i hit over 50 or so and i start pumpin the brakes

warped rotors?

that would be my guess, but then again, its only a guess

yup try that

If you don't pump the brakes, instead apply them consistenly does it behave the same?

From your description I would agree with the warped rotors theory.

thanks,but how much is this going to cost.

Depends on if you do the work yourself and what quality parts you get. And where you are located.

Cost me $60 for ceramic pads and $0 for new rotors.

Cheapo rotors should be about 20-30 and pads could be as cheap as 20

also check to see if everything is balanced too
