Whilst replacing my front pads on my 2000 1.4 Tdi I have managed strip the threads in the hub carrier that accepts the caliper mounting pins. I know school boy error. How can I fix this. Is it possible and safe to helicoil it. Whats the thread size? I have had a little measure and seems to be 9mm dia but pitch could be 1.5 or 1.25 can any body clarify this. If the hub carrier needs replacing do the carriers from fabia ibiza and other models fit. Thanks all
