1. Adjust the brake clearance: Hydraulic brakes usually need to adjust the brake clearance regularly to ensure good braking effect. You can find a professional auto mechanic to adjust the brake clearance. They will improve the braking effect by adjusting the gap between the brake pedal and the brake pad.
2. Check and replace the brake pads: Brake pads are an important part of the braking system. If the brake pads are badly worn, it will also affect the braking effect. You can ask professional technicians to check the wear of brake pads and replace them with new ones if necessary.
3. Check the brake fluid: Brake fluid is the transmission medium in the brake system. If the brake fluid is aged or polluted, it will also lead to poor braking effect. You can ask technicians to check the quality and water content of brake fluid, and change the brake fluid as needed.
4. Check other parts of the braking system: In addition to the brake clearance and brake pads, other parts of the braking system, such as brake disc, brake drum and brake oil pump, may also affect the braking effect. You can ask professional technicians to check the condition of these parts and repair or replace them in time.
In short, the poor braking effect may be caused by excessive oil braking clearance. You can solve this problem by the above methods. I suggest you find a professional technician to check and adjust as soon as possible to ensure driving safety.
