How to Adjust Promax Bike Brakes

    Step 1

    Put down the kickstand on your bicycle. If you have one, a designated workstand will make brake adjustment a quicker and easier process.

    Step 2

    Loosen the cable stop of the front brake using a 4 millimeter hex wrench. Turn the barrel adjuster on the side of the left brake lever clockwise until it stops against the brake lever housing.

    Step 3

    Use a pair of needle-nose pliers or similar to pull the brake cable taught in the front brake cable stop. The brake should close just slightly, but not completely against the rim. Tighten the cable stop using a 4 millimeter hex wrench and test the brake lever for a nice, stiff, quickly actuated brake. If the brake is too loose, turn the barrel adjuster counter-clockwise to tighten the cable increments at a time.

    Step 4

    Loosen the cable stop on the rear brake with a 4 millimeter hex wrench. Turn the barrel adjuster on the rear brake lever clockwise until it stops against the brake lever housing.

    Step 5

    Pull the brake cable taught in the rear brake cable stop with your needle-nose pliers. The brake should close slightly. Tighten the cable stop using a 4 millimeter hex wrench and test the brake lever for stiffness and actuation. If the brake is too loose, turn the barrel adjuster counter-clockwise to tighten the cable in small increments.

    Step 6

    Take the bike out for a test ride. While riding, test each brake individually and make adjustments to the barrel adjusters if necessary.
