I read into it, that it was all a relatively simple process. You just need to know how? Do's and songs etc.
I plan on taking on all work myself on my zed, right up to the clutch change. Ive got the garage, tools and im hoping the ability, Maybe 15-20 years ago I've changed engines on my mini, beetles, 3 x on my 205 and helped with my calibra. It Was a good time ago though!
But then brakes are quite important on a high performance car hey!!
