**Introduction:**
Hello everyone! Today, we’re going to learn how to adjust the rear brake of your electric bicycle, especially when the brake pads are rubbing against the disc. This is a crucial maintenance step to ensure your riding safety. Follow our steps to check and adjust your brake system together.
**Main Contents:**
**1. Inspect the Brake Disc and Pads**
Before making any adjustments, start by checking the condition of the brake disc. If the disc is heavily worn, uneven, or contaminated with oil, it should be replaced or cleaned. Also, examine the wear on the brake pads; if they are excessively worn, replace them with new ones. Ensure there are no foreign objects between the brake pads and the brake disc.
**2. Adjust the Brake Cable**
1. Release the brake lever and check the tension of the brake cable. If it’s too loose, tighten the cable to ensure there’s an appropriate distance between the brake lever and the brake caliper when the lever is at rest.
2. To adjust the brake cable tension, locate the cable anchor screw. Turn the screw counterclockwise to loosen the cable, then pull the cable tight to ensure a snug fit with the brake caliper. Finally, turn the screw clockwise to secure the cable in place.
**3. Adjust the Brake Pad Gap**
1. Make sure the brake lever is in the relaxed position, then lift the rear wheel off the ground. Spin the wheel by hand and observe the gap between the brake pads and the brake disc.
2. If the gap is too wide, adjust the screw on the brake caliper to bring the pads closer to the disc. If the gap is too narrow, turn the adjustment screw outward to maintain a proper distance between the pads and the disc.
3. During the adjustment, ensure that the gap between the brake pads and the disc is even, avoiding a situation where one side is tight and the other is loose.
**4. Check the Brake Lever Travel**
Adjust the travel of the brake lever so that the rider can easily engage the brakes while holding the lever, ensuring the lever's travel is ergonomic.
**5. Important Reminders**
1. Before making any adjustments, ensure the electric bicycle is turned off to prevent accidental injury.
2. During the adjustment process, be careful not to let brake fluid leak from the brake caliper, as this could affect braking performance.
3. If you encounter difficulties during the adjustment, it’s advisable to seek professional assistance rather than attempting to disassemble the brake system yourself.
**Conclusion:**
By following these steps, you can effectively adjust the rear brake of your electric bicycle, ensuring the brake system operates smoothly and safely.
