Changing girling brake pads 69, 144.

After 15 years ownership it's still not something I have done. any advice,tips etc would be appreciated. Is there a problem keeping the pistons off when pads removed?

In the absence of any other replies:

I'm not sure about the fronts as it is 45 years since I had my 145S, however, my C70 has the exact same calipers on the rears.

I punch out the holding pins and remove the spring clip, then gently prise one pad away from the disc and remove. I then give the brake pedal two full presses to activate the piston - this proves that the piston is free and an opportunity to check the rubber bellows. I then crack off the bleed nipple and press the piston fully back - catching any brake fluid in a container. Once the piston is fully retracted I clean up the pad slides, lube the pad with ceramic grease and refit in the caliper. I then repeat the same process for the other three pads, checking the fluid level in the reservoir as I go. Once all pads have been refitted, I refit the pins and springs. Depending on the pads the anti-squeal shims may be loose or attached to the pad, if loose carefully refit and line up with the pad.

All very straightforward and a job I do every year as part of the MOT yearly service.

Do be careful not to get any grease (copperease) on the pads or discs, just a smear on the pad seat areas, which are right by discs. .
