force. Check that the pedal stroke is within the range of the
specified stroke amount.

Check that warning lamp comes on when parking brake pedal is
depressed with in one notch.

ADJUSTMENT

To perform adjustment operations, remove tire from vehicle.

1.

Insert a deep-well socket wrench to rotate the adjusting nut to
loosen the cable sufficiently. Then, after returning the pedal
completely, adjust the clearance of the rear shoes.

2.

Using a wheel nut, fix the disc to the hub preventing it from tilt-
ing.

3.

Remove adjuster hole plug installed on the disc. Using a flat-
bladed screwdriver, turn the disc in direction as A as shown in
the figure until the disc is locked. After locking, turn the adjuster
to the opposite direction by 5 or 6 notches.

4.

Rotate the disc to make sure that there is no drag. Then install
the adjuster hole plug.

5.

After adjusting the clearance of the rear shoes, with no drag on
the rear brake, adjust the cable as follows:

a.

Operate the pedal 10 or more times with the force of 294 N (30
kg, 66 lb).

b.

Depress the pedal until a deep-well socket can be inserted.
Insert the deep-well socket, and rotate the adjusting nut to adjust the pedal stroke.

CAUTION:

Do not reuse the adjusting nut after removing it.

c.

After operating the pedal 3 to 4 times with the force of 196 N (20 kg, 44 lb), make sure that the pedal
stroke is within the specified value.

d.

With the pedal completely returned, make sure that there is no drag on the rear brake.
