1994 325 convertible. When braking I can feel a small 'jerk' through
the wheel for the first second then all is fine.
If I take my hands off the wheel and press the brakes I can see the
wheel kick around to the right by about 1 inch then it kicks back to
the original position. Braking after that is smooth etc.. No wobble or
vibration and car slows in a straight line...
Any clues please?
I've had this problem on two BMW's of similar ages to yours, each time
it was due to wear on the front discs. As they wear down, a shoulder is
left on the largest diameter of the discs and so when the brakes are
applied, the pads - or sometimes the metal backing plate of the discs,
contacts with this shoulder first which causes some inbalance but as
the pads met the discs they even up again. To cure this you can either
take off the shoulder with an angle grinder, or if they're too far gone
then replace them. If your're in the UK you can buy ATE discs from Euro
car parts at a much better price than BMW and they're the same thing!
