How to Bleed Mountain Bike Brakes: A Step-by-Step Guide for Maximum Efficiency
To bleed mountain bike brakes, first, remove the wheel and brake pads. Attach the bleed funnel and tubing to the brake lever and open the bleed port at the caliper. Pump the brake lever until the fluid flows through the tubing and the air bubbles are removed. Close the bleed port, remove the funnel, and reinstall the brake pads and wheel. Test the brakes to ensure they are working properly. Repeat the process on the other brake if needed.
