Adjustment

The difference in wheel braking force between the left and right wheels may deviate by max. 30 percent. In event of larger deviations of wheel braking force, carry out readjustment. It must be possible to brake to the point of locked wheels with the handbrake. The handbrake must be readjusted whenever the actuation stroke is greater than 10 teeth.
