U-Brakes
Begin by adjusting the pads of the U-brakes using a 10mm wrench. Make sure the
pad is hitting the rim and not the tire. Ideally the front of the pad should hit the rim
approximately 1mm before the rear pad.
Front U-Brake
Slide the brake cable and housing through the Housing Barrel and through the
cable anchor bolt. Set the cable clearance of 1mm between the brake pads and the
rim. Tighten the cable anchor bolt. All instructions shown are if you are looking at
the bike from the front. For brake adjustments, use a 13mm box end wrench and
a 5mm allen wrench. Loosen the 5mm allen bolt. For the drive side (left) of the
bike turn the spring tension nut with a 13mm box end wrench counter-clockwise to
increase tension on the spring. For the non-drive side (right), turn spring tension
nut with a box end wrench clockwise to increase tension on the spring. When the
desired tension is achieved hold the tension nut with the 13mm wrench and tighten
the 5mm allen bolt. The tension on each side should be equal so that the brake
arms move the same distance when the brake is activated.
Rear U-Brake
Option 1: Next, tighten the Cable Carrier to the brake cable approximately 20mm
from the brake arms when they are closed against the rim. Attach the Straddle
cable to the carrier. Hook cable end into the brake slot, pull excess straddle cable
through the cable anchor and tighten the cable anchor. Continue with “For Both
Options” below. Option 2: Place brake housing into the frame housing stops. Pull
brake cable tightly and thread across through the opposite cable anchor bolt. Tight-
en cable. Repeat for other side. Continue with “For Both Options” below.
For Both Options: For brake adjustments, use a 13mm open end wrench and a
5mm allen wrench and loosen the 5mm allen bolt. For the drive side (right) of the
bike turn the spring tension nut with a 13mm open end wrench counter clockwise to
increase tension on the spring. For the non-drive side (left), turn the spring tension
nut with a box end wrench clockwise to increase tension on the spring. When the
desired tension is achieved, hold the tension nut with the 13mm wrench and tighten
the 5mm allen bolt. The tension on each side should be equal so that the brake
arms move the same distance when the brake is activated. PLEASE NOTE that
some BMX frames have the U-Brake flipped and mounted below the seatstays. The
direction to tension the springs will still be oriented to how the picture is oriented.
