Remove the cassette housing control assembly.
Slowly rotate the torque gauge in the clockwise
direction and counterclockwise
direction of the take-up brake so that the reel
disk and the indicator of the torque gauge
rotate at an equal rate. Check that the values
are within the range of
direction
to
direction
to
and
that the brake torque in the
direction is at
least twice as high as that in the
direction.
Adjustment of the brake torque at the supply
side and the take-up side
If the supply or take-up brake torque is outside
the range, clean the supply or take-up reel disk
break lever felt, then recheck the torque.
If the supply or take-up brake torque is still
outside the range, replace the main brake or the
main brake spring.

Note:
When the main brake is replaced, perform the
height checking and adjustment (see page
