stripped off my calipers to get refurbed at bigg reds ,any one used them before ?,do they come back like new? do thay strip all the old paint off I know they will repaint at cost thinking of repainting myself what do you think get them to paint or spray myself

I've bought stuff from them before but not had any work done. I'd be confident in them doing a top job though. Personally, after all the trouble I had with doing mine, I would get them to paint them :) Yours will be like new as they replace all the seals and pistons and thoroughly clean them as well.

do you know where I can get a picture from on how all the shims fit back as im not 100% they have been fitted right from the last owner
