I just had my rear discs and pads replaced (2015 Golf). Everything seems fine, but if I'm backing up and press the brakes, there will be a "clunk" on one or both sides; when I then drive forward and press the brakes there will be another "clunk". It isn't loud, but it's clearly present.

If I don't switch directions and brake it won't happen again; only when I brake in reverse (and then the next time I brake going forwards). This didn't happen before the replacement, and I haven't heard it while driving other cars.

It sounds like the pads are sliding to one side of the calipers when I brake in one direction, and then the other side when I brake in the other direction. Is this right? Should I take it back to the shop and complain, or is this completely harmless? I don't care (much) about the noise; I just wonder if it's causing wear, or an indication of some other problem.

(I'm guessing this post was talking about the same problem, but it wasn't explained clearly and there were no answers.)

Could be a couple of problems but most likely in my mind is that the calipers are not properly fixed to the caliper brackets or the caliper brackets are not properly fixed to the the wheel hub.

I think my next move would be to CAREFULLY take it back to the shop and have them sort it out at their expense.

If the pads are sliding then they are the wrong pads for those calipers and that too needs to be corrected ASAP.

It is possible that the rear wheels nuts/bolts haven't been tightened correctly, which is allowing the disc/rotor to rotate slightly relative to the hub until it hits the studs, when you brake.
