M500 (RM400) 1973-75 (Hydro-Vac)
(RM400 redesignated to M500 in 1975 documentation)


Master Cyl:
Bendix Tandem (Dual)

Booster:
Dual Bendix Hydro-Vac
Combination Metering Valve / Brake Warning Switch

Front:
Kelsey Hayes Sliding Caliper Disc (Dual Piston) 13.36"

Rear (73-74 RM400; VIN R5):
Bendix Twinplex 15" x 4"

Rear (74-75 M500); VIN M5:
Bendix Duo-Servo 15" x 4"

Note:
The Dodge MH Service manuals indicate that 73-74 RM400 used Bendix Twinplex rear brakes and 74 later model M500 used Bendix Duo-Servo rear brakes however, none of the Dodge MH Parts manuals show parts for 74 later model M500 Bendix Duo-Servo 15" x 4" configuration.
Additionaly, aftermarket parts sites only show parts for the Bendix Twinplex 15" x 4" rear brakes.
Given that I can only locate information for the Bendix Twinplex 15" x 4" rear brake configuration I only list parts for that configuration.
