(3) Apply compressed air to the part indicated in
the figure and let the low and reverse brake
piston stroke three times.
Air pressure
98.1 kPa {1.0 kgf/cm
2
, 14 psi}
(4) Apply compressed air and operate the low
and reverse brake piston. Read the value
when the indicator of the dial gauge stops.
(5) Release the compressed air and read the dial
gauge when the low and reverse brake piston
is not operating.
(6) Calculate the low and reverse brake
clearance according to the following formula:
Step (4) value—Step (5) value= low and reverse brake clearance.
(7) Measure the clearances at four locations (90
°
apart) by following the steps from (3) to (6).
Verify that the average value is within the
specification below:
Low and reverse brake clearance
2.20—2.50 mm {0.087—0.098 in}
• If not within the specification, remove the
snap ring and measure its thickness.
(8) Add the thickness to the average value
calculated in step (7), and select the snap ring
whose range includes the value.
Snap ring seizes
(9) Install the selected snap ring and perform steps (2) to (7) again. Verify that the calculated value satisfies the
clearance specification.
12. Inspect the low and reverse brake operation by
applying compressed air as shown.
Air pressure
98.1 kPa {1.0 kgf/cm
