Martin, get the kit from BiggRed as above and ask for 2 new pistons (only £9 each). They are easy to do. Get the kit, pop them round to me on the car and we can rebuild them there and then, or I will see if I have some spares that need reconning, give me the seal kit and I will get the calipers painted up for you @ the same time.

Actually, are you @ the meet tomorrow @ Enfield? If so, come find me and we will go over all the faults with yours in one go, including the screen and the servo.
