How to Adjust Back Brakes on a Mountain Bike for Optimum Stopping Power
To adjust back brakes on a mountain bike, first, loosen the pinch bolt on the brake cable. Next, center the brake pads on the rim, making sure they are equidistant from the rim surface. Then, tighten the pinch bolt back up so that there’s no slack in the cable. Finally, adjust the brake pads outward to where they just touch the rim, and test the brakes to ensure they are properly adjusted.
