still had a grabby rear wheel on my DCT! I took off the parking brake -and wheel was still sticking -the disc getting warm in a couple of minutes run up on the centre stand.Not good
so decided to strip out the caliper again!
Thought i would be prepared so bought a Seeley piston removal tool - £18- like circlip pliers but once opened inside the piston you tighten a bolt that maintains the tension.
Except IT DOESNT FIT !
the closed setting is too wide for the rear brake pistons.
So thats going back
just telling you all in case you are thinking of buying one
Anyway I put a pair od pliers inside -gently and the piston moved -then I managed to get both out without a lot of effort
all back in place now after checking all -it WORKED!
