Chapter Three: Maintenance of Brake System
Section One: Structural Features of Brake System
A15 car is equipped with a diagonal dual-line vacuum assisted hydraulic brake system, which consists of two brake devices: service brake and parking brake. Front wheels adopt disk brake while rear wheel drum brake using self-regulated shoe plate clearance. Servo system uses high-performance vacuum booster and dual-way hydraulic braking master cylinder. A15 also features an ABS system, which greatly improves the directional control when braking and the braking performance as well. ABS also prevents wheels from being locked up, and maximizes the longitudinal adhesion of tires. That is how ABS ensures the steerability of front wheels and avoids skidding of rear wheels at the same time, thus ensuring vehicle braking with the maximum road adhesion coefficient. Parking brake control mechanism is located between the front seats, directly controls the arm drags of rear wheel drum brakes through a jacketed guy wire with small frictional resistance. Rear wheel brake also serves as parking brake; the simple and functional structure helps achieve high efficiency.
