Thank you very much for the reply's gents, John the piston diameter is approx 30mm, the handbrake lever is on top of the caliper. The two calipers have different methods of winding back the pistons, one has a screw driver slot the other a allen key. Other than being different sides they are identical.
Do you know what is the longer cable? As length may be a problem (is'nt it always :oops: !!! )
The pads look like MK2 to me :?: but been a while since i changed a set.
Once again thanks for the reply, any further thoughts would be great.
