ABSTRACT CLUTCH AND TRANSMISSION BRAKE ASSEMBLY A clutch and transmission brake assembly which can be readily incorporated into existing vehicle drive trains without undue modification. The assembly includes a wet clutch (10) connectable to a flywheel (12) and a transmission brake (16) located between the wet clutch and a transmission housing (14). The clutch and transmission brake are hydraulically operated by annular pistons (56,118) under the control of pressure responsive valves (202,204) which are operated sequentially by cams (268,270). These cams are interconnected with a pedal linkage (250,256,260) in such a manner that the clutch (10) is progressively disengaged as the pedal (250) is moved from an initial position (A) towards a dwell position (B). Further depression of the pedal results in the pedal moving through a dwell period (B-C) before the brake is progressively applied as the pedal moves from dwell position (C) to a fully depressed position (D). The pedal effort is arranged to increase as the pedal moves from the end of its dwell period towards the fully depressed position (D).
