How to Adjust Disc Brakes on Your Mountain Bike
To adjust disc brakes on a mountain bike, start by loosening the brake caliper mounting bolts and aligning the rotor between the brake pads. Tighten the mounting bolts and then adjust the brake pads by turning the adjustment knob or screw until they are evenly spaced from the rotor. Test the brake lever to ensure the pads are making good contact with the rotor and adjust further if necessary. Repeat for the other brake and test the overall braking performance before hitting the trails.
