OK, well an update on the progress: Went for a longish drive this morning to get oil up to temperature before having it drained and replaced. Then went and dropped off car and EBC Green Stuff at MMC. In retrospect I should probably have bought the Red Stuff as the little flyer the lady at hi Tech gave me said that Green Stuff were for cars up to 200BHP. Ah well - I'm sure they'll do fine. MMC just called me now and said that the discs were too thin and could not be machined (had kind of expected this after 11 years on the road). Luckily they have a set of front discs in stock and I'll have them replaced. I said to the guy that on a trip to Hamilton once, I had to hit the brakes from about 160km/h and the car pulled to the left - I wasn't sure if that was a L/R brake bias setting or something. He said that that was probably due to the left front caliper not releasing properly after application of the brake pedal. They had some difficulty getting the left caliper off and noted that the disc exhibited more wear than the other one. It's all being sorted now though.
