It's important to keep your cantilever brakes in working order. There are 3 main elements - the lever, the cable and the brake itself. Pads need to be checked most frequently, but are easily replaced if need be. As the pad wears sometimes you will need to correct the point of contact by adjusting the position of the brake.
This is a long guide, so you can choose to either watch the entire video above, or follow it in smaller chunks by clicking on the individual steps below.
Steps to Look After Cantilever Brakes On A Bike:
Brake pads wear in use and need to be replaced before the indicator slots disappear. Rubber hardens with age, so replacing old pads after a couple of years will improve braking performace regardless of wear. Some brakes have removable blocks that sit inside the shoe, these can be replaced independently without the need to replace the entire shoe. Other brakes have an integrated shoe, where the whole unit needs to be replaced.
