Welcome to my listing for a pair of Sinclair C5 brake adjuster screws. These are located on the underside of the C5 for both the front and rear brakes. The adjustment allows the brakes to be setup correctly for effective braking. These often corrode or snap and must be replaced.
To fit these you will need a 10mm spanner to remove/fit the brake cable from the front/rear brakes.
You will receive two brake adjuster screws.
