The quality of the car brake system is related to the life safety of the driver, so the quality of the brake system is very important, so how do we check the quality of the car brake system? What is a good car brake system?
1. Check the brake fluid volume. The storage volume of brake fluid should be between the upper and lower cut lines of the storage tank. If brake fluid is lacking, brake fluid of the same or the same brand should be added. Other brake fluid or alcohol substitute should not be added.
2. Check the leakage of the brake system. Check the technical status of the brake system to eliminate loosening, oil leakage or air leakage of the connecting parts.
3. Inspection under driving state. Start the engine, release the hand brake, and make the car drive at a speed of 20-30km/h. When pressing the brake pedal on the dry and straight road, the car should slow down and stop quickly without deviation. After braking the car, when the brake pedal is released and continues to drive, it should be able to start and run smoothly, and when the steering wheel is not moved in the running, the car should maintain a straight line without going astray.
4. Check the “foot feeling” of the brake pedal of the hydraulic brake system. Step down the brake pedal, first of all should be able to feel the pedal small free travel (in line with the requirements of various models), free travel should be between 6-20mm. Continue to press down the pedal, the pedal should have obvious resistance until the pedal does not move.
