BMW F10 brake judder
What causes brake judder on the F10?
The most common cause is an unevenly worn or warped brake disc. Dirt or rust between the disc and the hub, or wrong clearance on the centring collar, can make the disc run out. Clean the hub and the disc surfaces carefully during installation. A twisted front hub also causes vibration.
What is checked when the discs have already been replaced?
Check that the brake pad does not stick in its slot and that the caliper slide pins move. The caliper's end spring must be original and tight. Old pads with new discs may grip unevenly, and a new disc and pad set removed it.
Can shock absorbers, bearings or rods cause vibration?
Yes. Weak front shock absorbers can shake under light braking, and the thrust rod bushings can cause vibration and wandering. A wheel bearing can be checked by lifting the wheel in the air: a bearing fault is felt as vibration in the spring.
