The shoe must be slightly inclined in the
direction of rotation of the wheel. Other-
wise, braking will be poor and annoying
noises will be produced when the brakes
are applied (image 1).
Check the brake cables monthly for kinks,
rust, broken wires, and frayed ends, and
check the casings for any bent edges, cuts,
or frays. Replace any component that fails
the check.
In Cantilever type brakes, there must be a
distance of 20mm between the guide pulley
and the set of adjuster sleeve stop (image
2).
In V-Brake type brakes, if your shoes have
the possibility of regulating the distance
perpendicular to the braking track, make
sure that dimension A is equal to or greater
than 39mm, as indicated in the third gure.
Every 3 months, tighten the bolts on the
brake levers and shoes.
