loud clunk when braking from reverse??

[filip00]

so, i'm experiencing something really weird. i go in reverse, drive a bit, and when i apply the brakes, i hear a fairly loud clunk from the front, it occurs ONCE when the brakes are applied, and that's it. it brakes normally, goes normally, it just gives me that clunk when i go in reverse and when i brake, i hear it *clunk* but it brakes.

what the hell could that be??

One of your brake pads is sticking on the shelf in the caliper that allow the pad to move in and out relative to the disc.

Had the same issue with my 525. Reverse and clunk, but only the once for that day and it didn.t mater if the car was reversed first thing or last thing in the journey.

Simple cure is to remove the pads, clean up the caliper. Apply a very small amount of copper grease to the locating lugs on the pads and re-assemble.

I believe it was a build up of brake dust caused by cheap pads and an auto gearbox so the brakes get used more. In the end I just learnt to live with it, the e34 only did journeys in stop-start traffic so the pads were constantly creating dust.

if Omegas fix dont do it I would say its a ball joint, especially if it clunks while creeping slowly and jabbing the brakes.

Either capiper retaining bolt is loose on one side...

or...

Suspension bushing gone...

or

Something loosy in steering.

thanks for quick replies.

well, it appears to come from the right front wheel. i already disassembled the caliper, but the brakes were fine. i also did an inspection on the bearing, well, i just tried jerking it and spining it by hand, and it all seemed quite normal.

there is however a slight play in steering, which i think wasn't there before.

i will have my mechanic check the ball joint...

anyone else have any ideas, please share


cheers

I have exactly the same symptom - a clunk from the front when moving in reverse and applying brakes. Nothing else. Nothing has fallen off. brakes work fine, so I'm currently applying the wait and see solution ...

to solve this problem as well, it was one rubber joint that was loose.
