What is the working principle of an electronic parking brake?
1 Answers
Electronic parking brake works by using an electronic button control method, achieving parking brake control through the friction generated between the brake disc and brake pads. Definition of electronic parking brake: The electronic parking brake, also known as the Electronic Parking Brake (EPB) system, integrates the temporary braking during driving and the long-term parking braking functions, and realizes parking braking through electronic control technology. Precautions for using electronic parking brake: For the most common mechanical parking brake, first, be careful not to pull it up too hard every time you park, especially not to pull it to the end, as excessive stretching of the metal or keeping it stretched for a long time will accelerate deformation, leading to faster wear of the brake cable. The correct practice is to pull the handbrake until the rear wheels lock, then lift it 1-2 notches further to ensure the vehicle does not roll. If parking on a slope, it is not recommended to rely solely on the handbrake to secure the vehicle, as this will subject the handbrake to excessive braking force and accelerate its wear. The correct method is to first secure the vehicle with the handbrake after parking, then place reliable bricks or other objects under the tires. Once the wheels are firmly fixed, release the handbrake to transfer the force to the four wheels, then pull the handbrake again to share the load between the wheels and the handbrake.
