Front Brake Shudder

Yugo · #1 08-18-2011, 05:38 PM

Have an '02 X5. I just replaced my front brakes, rotors and calipers. Then, I replaced ball joints, upper and lower control arms. Now, brakes really shudder when I brake. Bought the Lemfoerder suspension parts. Was expecting it to drive like new but shudder seems to have gotten worse. Any suggestions? Thanks!

warped front rotor. Sometimes they aren't perfect out of the box.

Did you have an alignment done after the suspension install?

No, but I can't see how an alignment is going to cause the steering wheel to shake when I apply brakes at high speed. I also don't think its rotors because problem got worse just after I replaced ball joints, control arms and sway bars. If it were alignment wouldn't it track to one side or the other? It drives straight.

Actually you could be driving perfectly straight and have your toe or camber off--thus the shudder.

Anytime you replace lower control arms, an alignment is 100% necessary. I would tell you to start there.. It will probably fix the problem
