1. Feeling hard and not smooth when braking: This is a typical symptom of brake pads not returning to their original position. When you press the brake pedal, if you feel a short, hard, and not smooth stroke, it may be that the brake pads are not returning.
2. Reduced braking effect: If the brake pads do not return to their original position, the contact time between the brake pads and the brake disc will decrease, resulting in a decrease in braking effect.
3. Brake noise: If you hear a sharp metal friction sound while braking, it is likely due to the brake pads not returning.
Possible reasons
1. Brake pad wear: The brake pads will gradually wear out during long-term use. If worn excessively, it will cause the brake pads to not return to their original position.
2. Brake pad material issue: If the material of the brake pad is uneven or contains impurities, it may also cause the brake pad to not return to its original position.
3. Brake system malfunction: Various faults in the brake system, such as brake oil circuit blockage, brake booster pump failure, etc., may cause the brake pads to not return to their original positions.
Solution
1. Replace brake pads: If the brake pads are severely worn, the most effective solution is to replace them with new ones.
2. Check the brake system: If there is a malfunction in the brake system, it is necessary to repair or replace relevant components in a timely manner.
3. Use high-quality brake pads: Choosing high-quality brake pads can reduce the risk of brake pads not returning to their original position.
