Checking Brake Fluid Level
+Check ¯uid level in reservoir tank. It should be between Max
and Min lines on reservoir tank.
+ If ¯uid level is extremely low, check brake system for leaks.
+ If the brake warning lamp comes on, check brake ¯uid level
switch and parking brake switch.
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while engine is running.
Changing Brake Fluid
CAUTION:
+Re®ll with new brake ¯uid ``DOT 3''.
+ Always keep ¯uid level higher than minimum line on res-
ervoir tank.
+ Never reuse drained brake ¯uid.
+ Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and re®ll with new brake ¯uid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake ¯uid from each air bleeder valve by depressing brake pedal.
4. Re®ll until brake ¯uid comes out of each air bleeder valve. Use same procedure as in bleeding hydraulic system to re®ll
brake ¯uid. Refer to ``Bleeding Brake System'', BR-4.

Removal and Installation
WARNING:
Clean brake lining with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
CAUTION:
Make sure parking brake lever is released completely.
1. Release parking brake lever fully.
2. Remove rear propeller shaft and drum.
3. After removing shoe hold pin by rotating push retainer, removeleading shoe then remove trailing shoe.
Remove spring by rotating shoes in direction arrow.
4. Remove adjuster and return spring.
5. Disconnect parking brake cable from center brake lever.
Be careful not to damage parking brake cable when separat-
ing it.
6. Remove retainer ring with a suitable tool. Then separate cen- ter brake lever and brake shoe.

When installing, measure brake drum inside diameter and diameter
of brake shoes. Check that the difference between diameters is the
correct shoe clearance.Shoe clearance:0.25 - 0.4 mm (0.0098 - 0.0157 in)
If necessary, adjust by rotating adjuster.
Inspection Ð Drum
Standard inner diameter: 203.2 mm (8 in)
Maximum inner diameter: 204.5 mm (8.05 in)
Out-of-roundness (Ellipticity): 0.03 mm (0.0012 in) or less
Radial runout (Total indicator reading): 0.05 mm (0.0020 in) or less
+ Contact surface should be ®ne®nished with No. 120 to 150
emery paper.
+ Using a drum lathe, lathe brake drum if it shows scoring, par-
tial wear or stepped wear.
+ After brake drum has been completely reconditioned or
replaced, check drum and shoes for proper contact pattern.
Inspection Ð Lining
+Check lining thickness.
Lining wear limit: 1.5 mm (0.059 in)
Lining standard thickness: 5.1 mm (0.201 in)
Before installing new shoes, rotate nut until adjuster rod is at its
shortest point.
After installation, adjust shoe-to-drum clearance. Refer to Removal
and Installation.

System Description
OPERATION
Headlamp system on vehicles for North Europe contains a daytime light system. The unit operates to illumi-
nate headlamps low beam, parking, tail, license lamps and illuminations automatically in the following condi-
tions.
+The engine is running with lighting switch in OFF position.
When the any of following conditions exists, the daytime light operation will be canceled.
+Ignition switch is in any position other than ON
+Engine is stopped
+Lighting switch is turned to 1st or 2nd position.
If the daytime light system is canceled, lighting switch operations are the same as for conventional light sys-
tem.
DAYTIME LIGHT IS OPERATING
(With engine running and lighting switch in OFF position)
With engine running, power is supplied
+from alternator terminal L
+through daytime light control unit terminalj
8
+to base of transistor-2 in the daytime light control unit.
The transistor-2 supplies ground path to all relays. Then the relays energize to illuminate lamps.
