How to Repair Hydraulic Brakes on a Mountain Bike: A Comprehensive Guide
To repair hydraulic brakes on a mountain bike, you need to first identify the specific issue. If the brake lever feels spongy or the brake pads aren’t engaging properly, then air may be trapped in the system. To bleed the brakes, you’ll need to release any pressure in the system before attaching a bleed kit to the brake calipers and the lever. You can then pump hydraulic fluid through the system to remove air bubbles and restore brake performance. If the issue lies with the brake pads or rotors, you’ll need to remove and replace them.
