Brake Caliper Rebuild Help

soybmw · 11-26-2018, 07:14 PM

I recently bought used 335 brake calipers with plans to rebuild them and install them on my wagon. I have an appointment to have the brakes media blasted. Are there any precautions I need to take? Right now the calipers are completely disassembled. Should the bleed screws be put back in before media blasting? Anything I'm not thinking of? Thanks.

use foam ear plugs to plug the bleed holes. It's just to keep the threads from being damaged. The bore where the piston goes must also be protected. Put the piston back in, tape over it.

basically don't allow them to blast any honed or threaded surface.
