How to Easily Bleed Your Shimano Mountain Bike Brakes for Maximum Performance
To bleed Shimano mountain bike brakes you will need Shimano brake fluid, a bleed kit, and a 7mm wrench. First, remove the wheel and brake pads. Attach the bleed kit to the brake lever and fill with oil. Then, connect the other end of the bleed kit to the brake caliper and gently push the fluid through to remove any air bubbles. Repeat this process until all air bubbles are eliminated. Finally, reconnect the brake pads and wheel and test your brakes for proper function.
