After 3 months in lockdown finally got to the lock up and re-fitted the refurbished front brake caliper carriers with new guide pins, new discs and pads. Happy days.
Took it for a test drive, (and to make sure my eyesight was ok), Found that the brakes are binding and one of the rear ones which were also refurbished recently with new discs has bound on so badly that the disc is knackered and needs replacing.
Looks like I need to replace the brake pistons and seals. I should have just done them at the same time. I bet it’s a bigger of a job though!
