front end vibration when braking high speeds

[02 Black Gt]

i am having bad front end vibration when braking at high speeds from about 70 and up. arounnd 40 to 50 it doesnt vibrate at all. what do u think is the cause of this problem. i was thinking maybe warped rotors what about the ball joints. any ideas and help are greatly appreciated.

My car vibrates when braking hard from high speeds and a very slight vibration when braking hard on the highway. I assume your talking about your 92? I think its pretty normal for these cars. Does it vibrate anytime you touch the pedal on highway speeds or only when braking considerably hard?

I'd say warped rotors, but I'd check the ball joints too.

sometimes just when i touch it it will vibrate like no other its usually just when i have to slow down and i hiot the brakes normally it will shake really bad. i might just pull the rotors and have them checked. one of the rotors is only a year old.

Same problem here, gave her new rotors, problem went away.

I didn't change them out right away, the vibration slowly started getting worse from highway speeds down to city speeds.

Warped rotors.

its my 92. well i will have the rotors checked tomarrow and see what they say. if they check out fine i might as well just replace the ball joints.

Most likely it is the rotors.

here is the problem, due to the design of them, installing new ones is a bandaid fix. you will just shortly warp the new ones. Only way around it is to go 5 lug and install the sn95 brakes.

I have the same problem with my '92 only thing I havent changed up front would be sway bar bushings and ball joints.

well i dont want to get new rotors if they are just going to warp again. io do plan on doing a 5 lug conversion so maybe i will just wait til then. i will just go ahead and replace the balljoints and maybe the sway bar bushings and see what that does. they need to be replaced anyways. what are some good ball joints to get

There is another way, I have install cross drilled rotors on mine and the problem is gone. The drill holes help disapate the heat, helping them not warp. I've had them on for a while and they work great, they are factory replacement aswell so they went on easy. Cheap solution too

where did u get your rotors fpr and how much did they cost. also what are a good set of brake pads
