Abstract
This paper provides an overview of the brake system, namely, ABS braking system with conventional braking system in the structure and working principle of the similarities and differences, and ABS braking system has advantages. Then introduced sedan anti-lock braking system in the vehicle's location, analysis of the circuit ABS braking system structure, control relays, wheel speed sensors and actuators, where actuators are electro-hydraulic components, structure, complex, both contain hydraulic components, have received ECU control of electrical components, can effectively control each wheel hydraulic brake wheel cylinders increase, reduce or maintain, to prevent the wheels when braking Hugging, making the car get the best excellent braking effect. ABS actuator is actually controlled by the ECU of the brake pressure regulator device. Then on the disc (drum) brake system, vacuum brake booster and brake pedal assembly composition, inspection, assembly and adjustments of detail. Finally the micro-car brake system common failures, and analyze the failure causes and treatment.
Key words: Anti-lock braking system, ABS actuators, wheel speed sensor, parking brake, fault repair
