How to Effectively Tighten Disc Brakes on a Mountain Bike
To tighten disc brakes on a mountain bike, start by locating the adjustment barrel located near the brake lever. Turn the barrel clockwise to tighten the brake pads closer to the rotor. Test the brake by giving the wheel a spin, making sure the rotor does not rub against the brake pads excessively. If needed, adjust the brake pads individually using the adjustment screws. Keep checking the brake and make adjustments until the desired tension is achieved.
