George, was the part number I gave you for the seal kit the wrong one? I hope not! :?
Dave
Yeah... Tony kept saying "you want BR203410", and I replied "that's for a GTi isn't it?"
Once he'd sent it he then pointed-out that the
34 bit refers to it being 34mm, whereas the one I'd ordered (BR203010) is for a 30mm piston. - So back it went, but the new piston seems to be doing the job at the moment with the existing seals; I guess I'll see what the tester says.
The part numbers Bigg Red tell me you need for a rear caliper are:
Piston BRP233416 @£19.90 delivered (x2 if you want to do the entire axle
Seal kit BRK203410 @£26.90 for the entire axle... obviously I haven't tested if this is right yet, but the parts in the 30mm kit looked right (even if the piston seals were too small).
