Long time between updates but the project is still moving forward.

Brake master cylinder -

Raybestos MC390426 1 1/4" bore. This BMC is - ALMOST - a direct replacement. The flare fittings are a different size than Mitsubishi but that's easy enough. The unit is about 3" longer than the Mitsubishi BMCs. This means that the Group 65 battery will not fit in the standard location with this BMC installed.

I spoke to Steve at Dynatrac two weeks ago. Dynatrac uses the 'standard' late '90s Ford Exploder rear brakes on their rear axles. The information for that caliper and rotor are posted earlier in the thread. They use the 2004 Dodge 1500 4x4 front calipers and rotors on their D60 and D44 axles. The calipers are 2x2.12" dual piston with 13.22" rotors. The MC390426 should work just fine with this setup - provided an adjustable proportioning valve is used to dial down the rears.

So the existing plan is the Dynatrac D60 in the back with the D44 HP in the front. 6x5.5 with the D44 outers on the front axle. I just couldn't justify the D60 outers on the front.
