Ate caliper anti rattle shim

Did a mini service on front calipers today as the pistons were sticking. Noticed that front driver side was missing the anti rattle. Shims. Anyone know where I can get replacements?

if the pistons are seizing then you really need to get the piston out and clean the bore, remove the bore seal and clean the channel it sits in completely spotless.
As fluid is hygroscopic, it corrodes the seal channel, this pushes against the seal which constricts the piston release ability.
shims will not correct this
unless you did this and just want shims, to which I can't help

This I know. I saw that two of the four piston dust covers were split and I suspect there will be some corrosion in there. For now they are moving and I could back them off with a bar no probs. given them a good dose of brake cleaner. Next job will be to replace the dust covers, remove pistons and clean. Just happy that the pistons are on the move. Some very dubious looking bleed nipples too which will be fun.
Oh and front near side wheel bearing needs replacing also.
Still wanting to know where I can get anti rattle shims.

Brickwerks do a set of stainless steel shims at a very reasonable price.
