moin, I have big problems with my handbrake at the AUDI 80 B3. The reproduction no longer works (fixed gammelt) and it can only lie on the brake caliper. Now I want to change the brake caliper and have selected the brand NK at Carmaster.de, which are still relatively cheap. Can you buy the brand NK without thinking about it? or do you have to change the seals after 2 years? otherwise only Textar discs and re-installed. Should I still have new screws for fixing or can I use the old ones?
