Figure 16-3
3. Working one side at a time, remove three plugs from differential housing
(located at 12 o’clock, 4 o’clock and 8 o’clock). Put plugs aside.
4. Tighten each release screw revealed by the plugs, lightly until some resistance
is felt.
5. Working carefully, tighten each release screw only 1/2 turn (180°) at a
time, in sequence, until all three screws have been turned approximately
five full turns. Larger turns could cause components to bind and cause brake
failure.
6. Repeat this procedure on other side of differential. Parking brake should be
released.
TO RESTORE PARKING BRAKE
1. Make certain engine is stopped and all wheels are blocked.
2. Loosen each release screw, only 1/2 turn at a time, in sequence, until
each screw has lost contact with guide pin. Back out each screw until it
bottoms out against the stop. Then screw the bolts back in 1/4 turn.
3. Install plugs over each release screw.
4. Repeat procedure on other side of differential. Parking brake should be
restored to operation.
