How to Bleed the Brakes on Your Mountain Bike for Optimal Performance
To bleed brakes on a mountain bike, start by removing the brake pads and opening the bleeder valve. Connect a bleed kit to the valve and add brake fluid to the kit. Then, pump the brake lever to push out any air bubbles. Close the valve and remove the kit. Repeat the process for the other brake, and then test the brakes to ensure they are working properly.
