摘要： A golf car (10) having a hydraulic fluid brake system. The hydraulic fluid brake system (50) is implemented as a disk brake system which is responsive to hydraulic fluid pressure generated from a master cylinder (60). A brake pedal (80) and associated linkage (42) provides input to a master cylinder (60) to generate a hydraulic fluid pressure to control a brake caliper assembly (48). The brake pedal (80) has a range of travel, where a first portion of the range defines a service mode of operation and a second portion of the range defines a parking mode of operation. In the parking mode of operation, the brake pedal (80) and linkage (42) engages a detent (118, 120) to maintain application of the brake to provide a parking mode of operation. An accumulator (62) in the brake system provides an input force to maintain hydraulic fluid pressure sufficient to retain a parking mode of operation.
