Is it possible to rebuild Bembo 4 pot calipers?

Randy,

You can easily check them by using compressed air and by inserting a piece of wood where the pads/rotor should to prevent the pistons to falling off.If the pistons move freely you are on a good way!About the repaint there is two types :
the easy one to clean the caliper as better as you can , sand it lightly with 320 grit paper to don't paint the brake pad area (around the pistons) and to apply by brush a suitable brake color by foliatec as an example.The second is far more complicated as you have to remove the brake pad plates (these bolts are often serious rusted out) , to remove the x-over pipes and the bleeders then to put brake bleeders in the 5 outlets of each caliper , mask them and send the caliper(s),and brake pad plates to media blasting.After that you can have them powdercoated or professionally painted by a two stage auto paint.After that you replace the dust seals and maybe the piston seals (if they are soft and not cracked don't replace them).

P.S. are they 86 calipers ? look inside the caliper halves near the pistons area and you should see two digits in a circle it is the production year : 00 for 2000 model.
