How to Refill Brake Fluid on a Mountain Bike: A Step-by-Step Guide
To refill brake fluid on a mountain bike, first, remove the reservoir lid where the brake fluid is stored. Ensure that you use the recommended brake fluid type for your bike model, and slowly pour the fluid into the reservoir until it reaches the maximum line. Use a syringe to remove any air bubbles from the system, then tightly secure the reservoir lid. Squeeze the brake lever a few times to prime the system and test the brakes before riding.
