the brake shoes must be replaced. If the original brake shoes did not have channels, replace
them when the end of the rubber pad is only 3mm from the metal support.
Regulating the brake shoe vertically should be such that the edge of the rim is 1mm above
the end of the shoe. The shoe must come in contact with the rim exactly perpendicular to the

Once a month, check the brake cables for twisting, rust, broken threads and frayed ends, and
check that the housing is not crimped, cut or worn. Replace any component that does not pass
inspection.
In Cantilever brakes, there should be a distance of 20mm between the link unit and the end of
the brake cable housing support.
In V-Brakes, if the perpendicular distance to the braking surface can be regulated, make sure
that Distance A, as shown in the diagram below, is greater than or equal to 39mm.
Every 3 months, tighten the bolts in the brake levers and shoes.
Brake lever mounting bolt: 6-8Nm
Every 3 months, tighten the bolts in the Cantilever, V-Brake and Caliper brakes.
Brake shoe holder: 8-10Nm
Brake mounting bolt: 8-10Nm

Adjustment
Adjusting brake lever reach
It is possible to regulate the reach of some brake levers. Find the reach adjustment screw for
the lever. To increase the reach, turn the screw clockwise. To reduce the reach, turn the screw
counterclockwise.
On some occasions it is necessary to readjust the distance between the shoes and the rim after
adjusting lever reach.
Adjusting the distance between the shoes and the rim
To increase the distance to the rim, turn the reach adjustment screw clockwise. Turn it counter-
clockwise to reduce the distance.
If you cannot adjust the shoes in this manner, loosen the pinch bolt and tighten the cable again,
