How to Adjust Hydraulic Disc Brakes on a Mountain Bike – A Step by Step Guide
To adjust hydraulic disc brakes on a mountain bike, start by cycling the brake lever a few times to remove any air from the system. Then, use a hex wrench to loosen the caliper bolts and align them with the rotor. Squeeze the brake lever and tighten the bolts again. If the brakes are still loose, adjust the pads by turning the pad adjustment knobs. Finally, test the brakes by cycling the lever a few times before riding.
