Disassembly of the calipers:
Reanodized calipers:
Rebuilding calipers:
Quote:
Endless caliper rebuild kit includes a total of 4 caliper piston seals, 4 caliper piston dust seals, and one tube of silicone grease.

There are three different piston sizes, it's best to line up the seals accordingly before you start. First, the larger caliper piston seal goes in, then the smaller dust seal.

It's best to apply some grease onto latex gloves first, then apply it to the seal:

Installation of the seal is fairly straightforward, push one edge of the seal in and use index fingers to guide it in the groove. You can even use some brake fluid at this stage to make it easier, but that's not necessary.

Repeat above for remaining pistons and also the outer dust seal.
After this is done, the caliper pistons can be pressed in. There was enough silicone grease applied when the seals were installed to push in the pistons with ease. A bit of brake fluid can also be used to lubricate them.

All 12 pistons pushed in:

I also took the opportunity to clean up the hardware that's being reused.
Brake kit hardware (less bobbin pins):

The brake pad retaining clips need to be reinstalled. I had to purchase new hex bolts since the old ones were destroyed while removing them. Cost for heat-treated bolts were around $3-4 at King Bolt in Covina, CA.
Apply a small amount of ThreadLocker Red (high temp) to the bolt, and install the clips.

Caliper lettering sanding & reassembly:
Quote:
The caliper originally had shaved letters that were exposed. I knew I couldn't replicate the look 100%, but if I could get the letters fairly close to the look then I would be happy with it.
To sand, I started by masking off the letters completely. A small razor blade was used to cut out the lettering, creating a surface to sand with.

I used 3M Emery Cloth sandpaper (100 medium grit) to shave the letters. I simply tri-folded the sandpaper and used the pressure of my thumb to slowly remove the anodize. This wasn't the cleanest way, but it was pretty good considering the metal had all sorts of imperfections in the surface.

Here's a closeup; the edges are hard to get to without damaging the main body of the caliper, so I left it as-is. It won't be as clear once I have it on the car anyhow, brake dust will just cover it up.

Once both outer halves are done, it's time to reassemble the caliper...

As with most bolts that are in critical areas, apply a bit of high temp ThreadLock Red to the bolt.

Reassemble the bolts, and much like torquing down an engine head assembly or your wheels, you want to spread the load out as evenly as possible. I went from the innermost bolts outward, in an alternating fashion.

...aaand we're done with the calipers!

Caliper bleeder valves (Speed Bleeders) and fluid transfer tube:
Replacement rotors:
Completed caliper/rotor assembly:
Replacement pads: Project Mu HC+
New brake lines + brake install (finally)
Quote:
(I am skipping several steps in this last part. I am assuming you will know how to safely remove a brake line with a flared wrench, also assuming you know how to remove the stock brake calipers & rotors)
Finally got around to installing the calipers this week. First, a complete picture of all parts ready to go on the car + the brake lines.
It should be noted that I ended up using a set of Goodridge lines sourced from @FRSport.com

First to be installed (after removal of stock rotors and calipers) is the caliper adapter bracket. There's a couple of 10mm hex bolts that secure the bracket to the spindle, as well as the caliper to be bracket.

The rotors are next to go on. The calipers are then bolted on, then the pads inserted, then the pad retaining clip. It is a multi-step process but fairly straightforward.
Brake lines are also bolted on at this time.

After install the calipers are bled, starting from the rear to the front. I went RR/RL/FR/FL in sequence.
