Replace Bicycle Brake Pads

Brake pad assembly using a 5-mm fixing nut

Replacing standard bicycle brake pads is a fairly easy task requiring few tools and only marginal mechanical know-how. The most difficult part of brake pad replacement–knowledge of which style of brake pad is installed on the bicycle in question–is solved with a quick trip to the local bike shop.


Removing Bicycle Brake Pads

1. Loosen the nut on the brake pad fixing bolt assembly by turning clockwise.

2. Remove the fixing nut with your fingers. Pay careful attention to the way the brake pad fixing assembly is installed before removing the pad completely.

3. Repeat the first three steps as needed until all brake pads needing replacement are removed.

4. Turn the appropriate wrench counterclockwise to remove the fixing nut from the pad assembly and disassemble the pad.

5. Install the brake pad assembly loosely on the brake arm.

6. Finger-tighten the fixing nut to steady the pad by turning the nut clockwise.

7. Align the pad in the center of the braking surface of the rim as close to parallel with the surface as possible, and ensure the pad does not contact the tire either when in the rest position or when the brake is compressed against the rim.

8. Turn the appropriate wrench clockwise to tighten the fixing nut completely.

9. Repeat steps 1 through 5 as needed until all desired brake pads are installed.

Adjusting the Brake

10. Readjust one or both brake assemblies if needed by loosening–turning the wrench counterclockwise–the brake cable fixing bolt on the brake assembly.

11. Allow the cable to slacken until brake pad placement from the rim is normal.

12. Tighten the brake cable fixing bolt by turning the bolt clockwise.
