Tools Needed: Needle-nose pliers, hex wrench, replacement brake pads.
1. Removing the Brake Pads
a. Prepare the bike for maintenance. Start by turning off the bike and removing the battery.
b. Locate the brake pads. The brake pads are located inside the brake caliper on each wheel (refer to the photo).
c. Begin by removing the brake caliper. Use a hex wrench to remove the two brake caliper bolts from the bike frame (caution: be careful not to lose or misplace the washers inside the brake caliper bolts).
d. Carefully straighten the retaining pin with needle-nose pliers to remove the brake caliper bolts. Push up on the brake caliper.
e. Remove the old brake pads. Depress the spring plate to release the retaining pins and old brake pads.
2. Installing Brake Pads
a. Install the new brake pads into the brake caliper. Assemble the brake pads in the same configuration as the old ones. The friction material should be facing each other. Ensure that the top holes of each pad align with the retaining pin holes. Slide the new brake pads into the caliper to complete the installation.
b. Replace the brake pad retaining pins. Carefully bend the retaining pins to a 90° angle with needle-nose pliers to secure the brake caliper.
c. Reinstall the caliper. Position the caliper, aligning the mounting holes on the frame with the mounting points on the caliper. Insert the bolts with a hex wrench and tighten them evenly.
d. Before riding, reinstall the battery and test the brakes to ensure proper installation.
