Linear Pull Brakes
• Once the brake pads are properly positioned, loosen the cable anchor nut on the
Brake Arm (See Figure 65). Firmly squeeze the brake pads against the rim of the
tire, pull the cable taut, and re tighten the cable anchor nut using either (C) a 4, 5,
or 6 mm Allen Wrench or a pair of (E) Standard Slip Joint Pliers.)
• If the brake pads do not contact the rim at the same time, use (A) a Standard
Phillips Head Screwdrivers to turn the Adjustment Screws on the Brake Arm
until they contact the rim at the same time when pulling the brake lever.
Mechanical Disc Brakes
• To ensure that the brake caliper is positioned correctly, loosen the bolts holding
it in place, and position it so that the outside brake pad is slightly closer to the
rotor than the inside brake pad (see Figures 66 & 67). Then re-tighten those caliper
mounting bolts, alternating until they are both tight. Spin the wheel to make sure
there is no rubbing on any point on the rotor.)
• Squeeze the brake lever to test the caliper. The brake should fully engage
before the lever is pulled back to the handlebar. If you're able to pull the lever
all the way to the handlebar, or they feel too soft, use the barrel adjuster on the
Caliper and the Brake Lever to adjust the tension until it feels more firm.
Brake Levers
When squeezed, the brake lever should be firm and not bottom out against the
handlebar grip. To remove slack from the cable and make the lever more firm,
use the barrel adjuster on the brake lever or brake caliper. Unscrew the barrel
adjuster and locking nut one turn at a time until the desired firmness is achieved.
Keeping the barrel adjuster in place, tighten the locking nut back down against
the brake lever or brake caliper. If your brake lever is still too soft after adjusting,
further adjustment may be needed by a bicycle shop
WARNING:
If the barrel adjuster is loosened too much it may fall out, causing
brake failure.
