Abstract: A brake assembly is provided for implementation with a brake system and includes a support bracket, a master cylinder supported by the support bracket and operable to provide hydraulic pressure to the brake system, an accumulator piston extending from the master cylinder and operable to maintain hydraulic pressure within the hydraulic brake system, and an accumulator assembly extending from the support bracket. The accumulator assembly includes a compression plate engaging the accumulator piston, an end cap and an accumulator spring disposed between the compression plate and the end cap, biasing the compression plate against the accumulator piston. A booster arm is pivotally supported by the support bracket and is actuable between first and second positions. In the first position the booster arm limits axial movement of the compression plate against the accumulator piston and in the second position the booster arm permits increased axial movement thereof.
