So I got a set of pads and disks on clearance from an ebay seller for £47 and the good news is they are the right ones. Then there was the bad news. While eLearn clearly says to turn the pistons anti-clockwise to wind them in, “1. Use the tool to turn the brake calliper piston anticlockwise to move it back in its housing.” the piston only turned about 1/8th of a turn with the application of a fair bit of force before stopping. Measurement with a digital calliper over the ¼ turn it would move easily clearly showed the piston moved out when turned anti-clockwise. It took a lot of force to turn it clockwise and I was disturbed to see a small amount of fluid seep from under the boot. Nothing else to do but carry on, but sure enough after assembly I had a soft pedal and leaking calliper. I don’t know if I damaged the seal by turning it anti-clockwise, there was corrosion deeper in the cylinder or the hydraulic circuit was closed and I blew the seal. Maybe the ABS or hill-holder had closed the circuit, but eLearn gives nor info on that. As a precaution next time I’ll crack the bleed nipple before winding the piston in. So I’m now waiting for a recon calliper from Eurocarparts at £142 (less £35 deposit for the old calliper). Fortunately it was the right hand side that leaked as the left hand callipers don’t seem to be available. You can get a new piston and seal kit for under £20 but I don’t have proper facilities to clean the calliper and work on it. I’ve also never done one of the modern rear units with internal threaded adjuster and don’t have time to mess about with it.
Calliper arrives in two days so I’ll do the left side tomorrow.
Nearly forgot, the lining had separated due to rust.
