Bike Disc Brake Caliper Disassembly/Assembly (Avid BB7)

I show how to disassemble and re-assemble an Avid BB7 mechanical disc brake caliper. I also show how the mechanism works. I just thought it would be fun to see what was inside, and see how it works. I cleaned and lube the parts. I replaced the three ball bearings, but I really didn't need to. If they show wear or damage, they should be replaced. The ball bearings were 5/32" balls. I lubed the parts with marine grease. I considered using Sil-Glyde which I have used for disc brakes on cars. But I decided marine grease might be more available to people watching this video than Sil-Glyde.
