Has any one got one does it show how to replace small o ring on handbrake piston on 99 model it has a "tail" on the one caliper piston operated by hand brake lever .Do you remove rear plate with gasket or do it from inside brake piston hole .Basically dont want to bugger one up thats in already if cant get it out got new seal set inc o ring to go in.Ive got a manual on disc for K3 onwards but caliper is slightly different used to have 99 on cd but dont know where it is

OK sorted piece of cake once hand brake mechanism off

Just read your request but then noticed you had it sorted. Out of interest, where did you buy your seal set from for the rear calliper and how much did it cost ?
Its one of the jobs I intend to do so if you have any photos or tips then it would be much appreciated?
