When should brake pads be replaced?

Update time:2023-01-14

Replace brake shoes at 30,000-60,000 kilometers. Brake pads are vulnerable parts, and the replacement cycle of brake pads is determined according to the driving habits of the car owner. If the thickness of the brake pads of the vehicle is worn down to 1/3 of its original thickness, it needs to be replaced. If the brake pads do not slip in time, it will cause the vehicle to brake out of control and affect driving safety.

The following is how to replace the brake pads:

1. Before replacing the brake pads, you should first open the cover of the brake fluid reservoir in the engine compartment and check the height of the brake fluid page. If the brake fluid level exceeds the maximum limit, you should drain some of the brake fluid to prevent the brake fluid from spilling during the change.

2. Prepare the brake pads to be replaced and remove the wheel where the brake is located. Avoid scratching the rim during disassembly;

3. Use a wrench combined with a sleeve to remove the bolts of the brake caliper, and then remove the brake pads (if there is a brake induction wire, remove the brake induction wire first). Observe whether the brake pads are excessively worn or cracked, and if so, replace them in the next step;

4. Because there will be a lot of sand or mud in the brake caliper, it should be cleaned with a rag, and then coated with sound-absorbing paste to prevent abnormal noise during braking;

5. Use the piston pump to press the piston to the immovable position, and then install the brake pads to the brake caliper. After the new brake pads are installed in place (also install the brake sensing line), tighten the guide bolts to complete the installation;

6. After installation, cover the liquid storage tank cover, step on the brake pedal several times, and reset the brake. Then observe the height of the brake fluid, it should be within the appropriate height range;

7. After the replacement, carry out a test run to check whether the braking effect is reflected.
