Rear brake rebuild

I picked up my brakes and many other parts today from the powder-coating shop. These were the first batch of parts coated in the yellow that will be going on the frame.

I took this opportunity to quit work early, pick up the parts, and go home and get to the real work.

Here's how they look:
(I tried to adjust the color of the photo so it mostly resembles the actual color)

I spent about an hour, cleaning up the calipers again, after the powder coating. I removed small built up ridges of coating at the edges of the machined surfaces, I chased all the threads, I re-sanded the machined surfaces, scrubbed out the internals and cleaned very thoroughly.
Getting my parts laid out for the rebuild:
New parts:
black plastic cover
piston seals
o-ring gasket for between the 2 halves
spring keepers
brake pads
bleeder bolt cap

Re-used parts:
brake pad pins
cotter pins
bleeder bolt
metal shims
caliper itself

And the finished product!

I'm super happy with my yellow color choice! It was tough to make the decision as it really sets the tone for the whole bike. I'm waiting for my new brake pads to come in the mail right now, so the above photo is less the pads. Additionally, I'm getting a custom made braided stainless brake line. The next step is to refinish and rebuild the master brake cylinder.

Tomorrow I'll be sand blasting the rear master cylinder, sanding out and clear coating. I'm doing rid of the black plastic cover that goes over the master cylinder. Unnecessary part!
