DETAILED MAINTENANCE
On some newer type cantilever brakes, the main brake cable continues
through the central cable carrier to an anchor bolt on one of the brake arms.
A shorter link cable reaches form the carrier and the hook on the other brake
arm. Adjustment of the cable length is made after loosening the anchor bolt
on the brake arm. Adjust the brake pad position so that it is parallel to the
wheel rim and so that the leading edge makes first contact.
To do this, fit an Allen key into the brake pad holding bolt, loosen the fixing
nut and adjust. Move the brake pad along its mounting post to alter the
distance from the rim, and move the curved adjustment washer to alter the
angle of the pad.
On some models there is a spring-force adjustment screw on the brake arm
that allows further fine turning of the brake shoe position.
Bicycles with cantilever brakes must be fitted with safety devices to prevent
a possible accident in the event of the brake control cable or the straddle
bridge becoming loose or breaking while riding.
These are usually the reflector brackets, and must be fitted in the front and
rear. The bracket will prevent the straddle cable from interfering with the
wheel should the cable become disconnected from the control cable. If the
reflector brackets are not fitted in this position, then alternative emergency
cable safety stops must still be fitted.
