Front Brakes

1. Remove the front calliper with the mini multi-tool included with the bike. Unscrew both bolts and carefully remove the calliper.

2. Remove the bolt on the calliper with a 3mm Allen Key. 

3. Remove the brake pads. Do not touch the brake pad surfaces with your fingers.

4. Sand the brake pads with a piece of fine-grade sandpaper until the surfaces are shiny and free of any visible contaminants.

5. Wipe the brake pads with rubbing alcohol and a piece of clean cloth and allow them to dry completely.  

6. Repeat steps 4 and 5 on the brake rotor.

7. Reinstall the parts, being careful not to touch the surfaces as the oil from your fingers can contaminate the pads and rotor again.

Rear Brakes
