(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
