2007 front brake upgrade:
Chevy '71-'78 1/2 ton or light 3/4 ton Dana 44 front caliper brackets and calipers
Pads: NAPA TruStop TS728AM
Rotors: '77/'78 CJ5 vented rotors (1 1/8" thick) Raybestos 3550R
Brake hoses: Chevy 1/2 ton OEM Napa 36759 (right), 36760 (left)
Combination Valve: '97 Jeep TJ .....Note: this valve is actually three valves in one: a Metering Valve which engages the rear brakes before the fronts; Proportioning Valve which allows only a certain percentage - perhaps 70% - of the hydraulic braking pressure to go to the rear wheels; a Pressure Differential Switch which detects if one of the the two brake circuits has lost pressure - a dashboard light is illuminated.
2007 dual master cylinder upgrade:
Raybestos MC36456
- originally designed for AMC Hornet SST & Javelin vehicles
- master cylinder bore: 1-1/16"
- ports for brake lines are both 1/2" X 20tpi
Note: the 1971-78 Chevy pickup calipers had a 1-1/8" piston in their GM factory master cylinder - this 1/16" difference in piston diameter will no doubt cause a longer brake pedal travel than expected.

Gauges: Original fuel and temperature gauges are supplimented with ammeter, oil pressure (as well as a modern radio). In future, all additional gauges could be hidden behind the metal blank on the dashboard in front of the steering wheel. The metal blank would hinge downward so that the gauges/radio can be viewed and accessed. The idea for the concealed gauges came from the now defunct “Wicked Willys” website:(http://www.slick-willys.com/wagon.htm) |
