Shuddering after replacing brakes - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I recently replaced the front brake pads, rotors, and calipers on my 2000 ZX2. Shortly after, the car began to shudder when I would apply the brakes. It feels to be coming primarily from the front driver side, although that could be in my head. I have avoided driving my ZX2 since this began for fear of warping the rotors or causing any other damage. I am about to jack it back up now to see if anything stands out as the problem, but figured I’d post here as well to see how common this is and if there are any easy fixes. Thanks!

Were the rotors OEM or a good brand? The Chinese rotors can be warped from the factory.

If you put car on a brake tester / rolling road , and run each wheel individually , this should show what wheel/s are causing judder and also checks brake balance . As already suggested , could also check discs for runout . If still having probs .check susp/ bushes / steering for any abnormal wear which would allow " kicking " when brakes applied .

Be sure to break in the brakes as well. Find a secluded (paved) sideroad, and brake medium/hard or similar to a panic stop from at least 45mph a few times to seat the pads onto the rotors.

Yes, the Chinese rotors aren't the best at coming out of the factory flat!
