Where is the ABS master cylinder located in a car?
1 Answers
Automobile ABS master cylinder is located in the engine compartment near the firewall. The functions of ABS are: 1. To maximize the effectiveness of the brakes, shortening braking time and distance; 2. To effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; 3. To allow steering during emergency braking, providing good steering control; 4. To avoid severe friction between tires and the ground, reducing tire wear. The working principle of ABS is: during braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve of the wheel that is starting to lock up to keep the braking force constant. If the wheel continues to lock up, it opens the normally closed output solenoid valve, causing the braking pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force.
