Brake pads
1/ Check the pad is aligned with the edge of the rim.
2/ Check the distance of the pads from the rim (1 to 3mm for optimum braking).
3/ Always lift the pads off the rim a bit to the rear.
4/ Check that the V-Brake or Cantilever calipers are symmetrical.

Caliper brakes (U-type)
The braking device is located inside the hub: the brake can be activated by a lever (drum
brake) or by the pedals (coaster brake)
Coaster brake: the brake is activated when you peddle backwards. The brake must be applied before the crank has rotated 60 degrees (1/6 turn). The chain activates the brake. It's
important to check that the tension is correct to prevent chain derailment. The permissible range of vertical movement for the chain is detailed in the «Adjusting chain tension» section.
