Although by now all know Skoda discs are so poor, I thought will share my experience in old thread. Changed all front and rear at 48500 miles/ 5 years, started to hear grinding noise and some rear pads were shot. Discs look horrendous but amazingly measuring thickness they still had ...in theory (poor surface affects braking efficiency I think)....few mm of life left. Similar most pads had 4-6mm life left but 2 rear pads were destroyed by poor disc surface. I recon could do 100000 miles looking at thickness if not for the poor quality. I was surprised inside of front discs looked much worse then outside. After shopping around (independent garages, kwikfit/National (just to check prices -, one of them quoted £725 for all discs/pads - Delphi), Skoda dealer came much cheaper at £417 for Ferrodo Premier and got my business. Did not fancy to buy myself with garage fit only and do not have fitting warranty in case bought parts would have defects. Dealer told me part of the problem with rear disc poor "cleaning" how he called it could be my engine braking....not convinced...My work pal 1 year old Golf has poor rear discs as well, front looks good.
