Mastering Your Ride: How to Tighten Brakes on a Mountain Bike
To tighten brakes on a mountain bike, start by locating the barrel adjuster on the brake lever. Turn the barrel adjuster clockwise to tighten the brake cable tension. If the brakes still feel loose, adjust the brake pads by using the Allen wrench to turn the pad adjuster. Push the brake lever firmly and check if the brake pads are making full and even contact with the rim. Test ride the bike and make further adjustments if necessary.
