Thankyou for the advice on my problem, with the handbrake. Unfortunately the suggestions didn't help I started to think maybe as they sent the wrong discs was the Calliper also the wrong one it looked the same fitted the same even had the same number on it.
I was all for getting it to the garage in the village only a few hundred yards from my house, and paying for the privilege of them telling me, their trained mechanics, and I should have left well alone. Fair point I suppose but it was taking it to a garage that got me in the position I'm in now.
As I needed the car for work, I decided to refit the original calliper, also to see if it cured the handbrake problem that I had with the new calliper. Straight away the handbrake worked fine.
I am going to replace the discs, pads, probably the callipers on both sides, just for piece of mind, the n/s calliper was a very rusty and stiff this was meant to have been changed only nine months ago! Didn't look it though.
Now I have to see if I can return the discs and Calliper, which came from Germany, lesson learnt here the parts did look good, but are really expensive to return, if wrong in my case. May have to put it down to experience. Never mind the money I'm saving doing it myself will cover the cost of the parts. Sorry to ramble on but you learn by others mistakes, so if this helps anyone all to the good.
Once again thanks for the advice
