How to Effectively Bleed Your Mountain Bike Hydraulic Brakes: A Complete Guide
To bleed mountain bike hydraulic brakes, first, remove the wheel from the bike and disconnect the brake hoses from the brake lever and caliper. Then, use a bleed kit to attach a syringe filled with brake fluid to the caliper and another to the lever. Open the bleed port at the caliper and slowly inject the fluid into the caliper until it comes out of the bleed port. Repeat the process at the lever, taking care to avoid air bubbles. Finally, reconnect the brake hoses, replace the wheel, and test the brakes thoroughly.
