my girls civic was doing the high speed vibration while braking coming off the interstate. Her rotors were warped pretty bad
Paull: sounds like you have air in the lines or more likely a bad master cyl.
He could just need new pads......
I disagree.
Pads dont cause the vibration warped rotors do.
I would tend to steer my cause towards the rotors.
As for the warranty on those rotors you may be screwed seeing that particular company doesnt service the state you reside in now. sorry....
Paul:If your master cylinder is/was low there is a really good chance theres a leak.You seriously should have a friend or mechanic check out the source of the leak.I mean look at the brake fluid system this way....if the fluids disappearing wheres it going?It doesnt just evaporate in a closed system.
I'm willing to bet you have a leaky rear wheel cylinder.
jaowli:With your high speed vibration I would think that your frt rotors are mildly warped.It just intensifies with speed.
Also just the steering wheel shakes right? Not the whole car?
A little test I do is to drive about 20-30 mph and
slightly apply the park brake.If the vibration appears with the e-brake application then the rear drums are the culprit.If not I rule out the drums as a suspect.
I dont know what auto part store is local to you,but most offer machining services at decent rates.I'd take the rotors to them for machining.
Oh and one last thing,after you remove the rotors from the car look at the hubs where the rotor mounts.Is the rotor mounting surface clean or rusted real bad?
I have had concerns in the past with customer cars having vibrations from rust behind the rotor mount surface.You can see how rust build up can cause the rotor to not seat properly and cause a vibration.
Good luck.
