After some leaks from my front M callipers and some advice on stock brake balancing from Eric, I've reverted to stock calipers up front.

Just rebuilding the seals, and the kit comes with these plates.



Are they supposed to attach between the brake piston and pad?
Are they essential?
Which side goes against the piston?
Has anyone got a close up photo of one fitted - can't find any photos or diagrams on the world or pelican??

My understand theyre needed and snap onto the piston. They adjust the pad clearance I think. I'm sure someone more knowledgeable will chime in.

Thanks for that, I've squashed them into the recess in the brake piston and put the pads and retaining pins in - seems okay!

If the pistons are correctly clocked they snap right in. The recess in the piston is to prevent wedge shape wear on the pads.

Thanks Bruce, I did need to tweak the tabs slightly to get them to slot in okay. I didn't have these on the M calipers and wanted to make sure I got them on right!
