One of my front disc brakes has developed a regular knock/tap noise with each revolution of the wheel. I've had it looked at by a Sunbeam specialist workshop here in the UK, and they tried copper grease on the backs of the pads, but were unable to fix it. It is definitely linked with the brakes, because a light application of the pedal stops it for a short while. The workshop's opinion is that it is caused by the disc pad being knocked back slightly against the caliper, due to wear in the caliper (which are rebuilt original ones, rather than new) and a slight eccentricity of the wheel or disc as it rotates. Does this seem feasible? I had the front wheel bearings changed recently, so I'm wondering if that has anything to do with it. I don't think its a serious problem, but it is annoying. Any suggestions please? The car is an S3, but as the calipers are rebuilds, I don't know what series they were from originally. Regards and thanks. Steve
