I have replaced the pads on the rear but had issues with the offside (right hand) caliper and faults thrown up subsequently. Works intermittently but not reliably. I have removed as dis-assembled the caliper, motor off and piston removed to check if any damage was caused. I have pictures of the inners to show you guys whats in there. New here so any pointers on how to get them displayed here would be great. Theresa small ring that had been damaged, have another to replace it with but cant see any logical placement for it. Thanks in advance.
