Cam Lever Angle Inspection
Check that the rear brake cam lever comes to an 80° ∼
90° angle [A] with the rear brake rod when the rear brake
is fully applied.
If it does not, adjust the rear brake cam lever angle.
Cam Lever Angle
80° ∼ 90°
Since a cam lever angle greater than 90° reduces
braking effectiveness, cam lever angle adjustment
should not be neglected.

Cam Lever Bolt
Before removing the brake cam lever, mark on the cam
lever and camshaft at the same position.
Mount the cam lever on the camshaft moving it one ser-
ration at a time from the original position so that the cam
lever has the specified angle.
When remounting the cam lever, be sure that the
position of the wear indicator on the serrated shaft
is not altered.
A change in cam lever angle is caused by wear of
internal brake parts. Whenever the cam lever angle
is adjusted, also check for drag and proper opera-
tion, taking particular note of the brake lining wear
In case of doubt as to braking effectiveness, disas-
semble and inspect all internal brake parts. Worn
parts could cause the brake to lock or fail.
