How to replace the brake pads of a KETELES electric bicycle?

Changing the brake pads on an electric bicycle is important. It helps extend the bike's life and improves safety while riding. Using the KETELES electric bicycle as an example, changing the brake pads is fairly simple.

However, you should still pay attention to the details and how to use the tools. This article will explain the steps and precautions for replacing the brake pads on an electric bicycle. This approach ensures that even those with little experience can complete the task confidently and without difficulty.

Preparation: Make sure everything goes smoothly

1. Tool list:

1. Wrench: It is recommended to use a multi-functional hexagonal wrench to adapt to different screw specifications.

2. Screwdriver: Use either a flat-head or Phillips-head type, depending on the specific screw design.

3. Cleaning cloth and alcohol: Clean the brake system to prevent dust from affecting installation.

4. New brake pads: Make sure they are compatible with your KETELES model (can be purchased through the official website).

2. Working environment:

1. Find a bright and spacious place to avoid small parts from getting lost.

2. Turn off the bicycle’s power and remove the battery to prevent accidental electric shock.

Tip: Before starting, wear protective gloves to protect your hands from oil and scratches.

Detailed steps

1. Loosen the brake screws

• Use the short end of the wrench to loosen the two screws that secure the brake caliper, then switch to the long end to quickly remove it.
• The screws may become tight because of long-term use. Be careful to apply force steadily to avoid damaging the threads.
• Carefully remove the caliper and gently hang it next to the frame to avoid pulling the brake line

 

2. Remove the screws that secure the brake pads

• Inside the brake caliper, find the small screws that secure the brake pads in the brake. Use an appropriate wrench to easily remove them, and wipe the surface of the screws with a cleaning cloth if necessary.

 

3. Remove the old brake pads

• Gently remove the brake pads from the caliper. If the brake pads are tight because of wear, you can carefully pry them off with a flat-head screwdriver.
• When removing the brake pads, note their direction and position to correctly install the new pads.
• Check the surface of the brake disc for obvious scratches or deformation. If there are any aberrant, you may need to replace the brake disc together.

 

4. Install the new brake pad

• Follow the instructions in the new brake pad packaging and align it with the slot of the caliper. Make sure the direction is correct, usually, the friction surface of the brake pad should face the brake disc.
• After the brake pad is installed in place, press it gently with your hand to ensure that it is firmly fixed.

 

 

5. Reassemble the brake

• Reinstall the brake caliper onto the brake disc, aligning it with the screw holes. First screw the screws into place by hand, then tighten them with a wrench to ensure they are not loose.

 

6. Adjust the brake pad spacing

• Adjust the gap between the brake pad and the brake disc to avoid friction. For mechanical brakes, fine-tune the brake line; for hydraulic brakes, pay attention to the oil pressure balance.

7. Test the braking effect

• Turn the wheel and pull the brake handle to confirm that the brake pad can smoothly contact the brake disc and stop the wheel in time. If the brake is too tight or weak, adjust it again.

Precautions after replacement

1. Brake pad running-in: New brake pads need to be ridden several times to achieve the best braking effect. Braking may be slightly sluggish when just installed, which is normal.

2. Check the brake system: Confirm that the brake disc has no obvious scratches or deformation. If you find any problem with the brake disc, promptly fix it or replace it to ensure safety and optimal performance.

3. Regular maintenance: It is a good idea to check the brake pads every 500 to 1000 kilometers. This is especially important for those who ride on rough terrain often.

Frequently Asked Questions and Answers

• Do the brakes make noises after the brake pads are installed?

It may be that there is dust or oil on the surface of the brake pads and brake discs, which can be wiped with alcohol.

• Do the brakes feel too hard or too soft?

Adjust the brake line properly to ensure optimal performance and safety. If you see problems, check the hydraulic system. It might need more brake fluid or venting to remove air bubbles.

Conclusion

Regular maintenance of your brake system enhances your e-bike's performance, ensuring a safer and more enjoyable riding experience. If you still have questions, you can refer to the KETELES official manual or contact our after-sales support.
