Adjustment
To adjust the reach to the brake lever
With some brake levers, you can change the reach, the distance
from the handlebar to the lever.
1. Locate the reach adjustment screw (Figure 3.7.3) and turn.
To increase the reach, turn the screw in (clockwise). To
reduce the reach, turn the screw out (counter-clockwise).
2. If needed after adjusting the reach, re-adjust the pad
clearance.
To adjust brake pad clearance to the rim
1. Turn the barrel adjuster. To increase the pad clearance,
turn the barrel adjuster in (clockwise). To reduce the pad
clearance, turn the barrel adjuster out (counter-clockwise).
For most direct-pull systems, the barrel adjuster is on lever
(Figure 3.7.3).
With a double-pull lever (Figure 3.7.4) adjust the cable
tensions so that the rear brake pads are at least as close to
the rim as the front brake pads.
2. If the brake pads cannot be adjusted properly
in this manner, loosen the cable clamp bolt and
re-attach the cable as in To install a brake cable,
but without removing the cable.
To center a V-type brake
1. Rotate the centering screw (Figure 3.7.1).
Turn in small increments and check for
centering.
2. If the brake has two centering screws, adjust
the overall spring tension while centering the brake.
