Dave's Place - 1973-75 Dodge Class A M500/RM400 (Hydro-Vac) Motorhome Brakes

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.
