Abstract
A compound master brake cylinder assembly (10) for a braking system, the cylinder assembly having a reservoir (34), a first low pressure cylinder (72), and a removable high pressure cylinder (58). A relief valve (84) is provided with a poppet valve (104) normally biased to a closed position. The relief valve (84) extends between the low pressure cylinder (72) and reservoir (34) and is responsive to first cylinder (72) pressure and outlet pressure through pilot passageways (114 and 111, respectively) to vent fluid from cylinder (72) to reservoir (34) to progressively reduce the pressure in the cylinder to insure that the force applied by push rod (14) does not substantially vary while cylinder (72) pressure is being reduced after outlet pressure exceeds a predetermined position.
