I just got the brakes installed on the weekend. Due to me hurrying and not reading the instructions, I threaded the brake line screw insert in the calliper. I tell you what, I was not a happy chap for doing that. Anyway, I called a mobile mechanic who rethreaded it for me. Since they were the brakes and did not want to do it again, I asked him to fit it and he did it for $250. The majority of the time was threading the calliper and cleaning it out. Any way, its all on my car and looks sweet.....
