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.

1. Ensure vehicle is unladen condition*.* Fuel, radiator coolant and engine oil full. Spare tire, jack,hand tools and mats in designated positions.
2. Have a driver sit in the driver's seat and one person sit on the rear end. Then have the person on the rear end slowly get off
the vehicle. This is necessary to stabilize suspension de¯ec-
tion.
3. Gradually depress brake pedal and attach a lever to the stop- per bolt, then adjust length ``L'' as follows:Length ``L'': Approx. 175.2 - 178.2 mm (6.90 - 7.02 in)
4. Remove front LH tire.
5. Connect tool to air bleeders on front LH brake caliper and rear LH or RH brake wheel cylinder.
6. Install front LH tire.
Before installing front LH tire, con®rm the tool is not touching
the front LH wheel.
7. Bleed air from Tool.
8. Raise front brake pressure to 4,904 kPa (49.0 bar, 50 kg/cm
2,
711 psi) and 9,807 kPa (98.1 bar, 100 kg/cm2, 1,422 psi) and
check rear brake pressure. Rear brake pressure: Refer to table on next page.

REMOVAL AND INSTALLATION
CAUTION:
When installing vacuum hoses, pay attention to the following
points.
+Do not apply any oil or lubricants to vacuum hose and
check valve.
+ Insert vacuum tube into vacuum hose as shown.
+ Install check valve, paying attention to its direction.
INSPECTION
Hoses and connectors
Check vacuum lines, connections and check valve for airtightness,
improper attachment cha®ng and deterioration.
Check valve
Check vacuum with a vacuum pump.
Connect to booster
side Vacuum should exist.
Connect to engine
side Vacuum should not exist.
Vacuum warning switch*
Test continuity through vacuum warning switch with an ohmme-
ter and vacuum pump.

Removal and Installation
1. Rotate crankshaft so intake cam nose for No. 1 cylinder facesstraight up when viewed through oil ®ller cap mounting hole.
2. Rotate crankshaft approximately 240É counterclockwise.
3. Remove vacuum pump.
CAUTION: Loosen mounting nuts equally and gradually.
Always remove mounting nuts by pushing to keep the
vacuum pump from jumping up.
Do not disassemble vacuum pump.
4. Install the vacuum pump in the location from which it was removed with cam nose set in position.
