How to Adjust Rear Brakes on a Mountain Bike for Optimal Performance
To adjust the rear brakes on a mountain bike, first ensure that the brake pads are properly aligned with the rim. Then, adjust the tension on the brake cable by either tightening or loosening the barrel adjuster or adjusting the cable at the brake caliper. Once the tension is adjusted properly, test the brakes by squeezing the brake levers to ensure that the pads make proper contact with the rim and that the bike comes to a controlled stop.
