Cantilever Brakes - Utilizing a Straddle Cable
The length of the straddle cable, the height of the straddle hanger, and
the brake pad-to-caliper arm position all have an effect on braking
power. Generally, the straddle cable bridge is set low and close to the
tire for maximum braking force. The straddle cable should be high
enough, however, to adequately clear the tire (and any debris that may
stick to the tire) or to fit over the front reflector hanger. In the event of
brake cable failure, the front reflector hanger would prevent the strad-
dle cable from catching in the tire and locking up the front wheel. The
straddle cable length (when adjustable) is set to transfer as much
force to the brake pads as possible. For the most efficient transfer of
force, the straddle cable and the line between the
cantilever pivot and the cable anchor should form a right angle (90
degrees). If the force is not at a right angle, part of the force gets
wasted in pulling on the brake post, which has no effect on braking.
Brake pad aligned with the rim surface Pad and rim should be parallel.
