4) Failure on front master cylinder.
In case of failure on front master cylinder the pressure on the inlet port (C) drop to zero. The pressure from inlet port
(A) acts on the bypass piston (2) and move it by comprising
of bypass spring (3). It makes possible the communication
between the inlet port (A) to outlet port (B) through the
bypass system. The outlet pressure (B) reaches the inlet
pressure (A) and the LSPV is bypassed.


Valve Maintenance
In the case to fluid lead or other a abnormalities, faulty valve
should be replaced.
Note:
The load sensing proportioning valve is not repairable and
must be replaced as a completed assembly.

Service Precaution
Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNECESSARY SRS
SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU/GM will call out those fasteners that require
a replacement after removal. ISUZU/GM will also
call out the fasteners that require thread lockers o
r
thread sealant. UNLESS OTHERWISE SPECIFIED,
do not use supplemental coatings (paints, greases,
or other corrosion inhibitors) on threaded fasteners
or fastener joint interfaces. Generally, such
coatings adversely affect the fastener torque and
the joint clamping force, and may damage the
fastener. When you install fasteners, use the
correct tightening sequence and specifications.
Following these instructions can help you avoid
damage to parts and systems.
General Description
Pulling up the parking brake lever by hand will set the
parking brake. By means of a ratchet type lock, the
lever can be held in that position until it is released. The
position of the lever is transmitted through cable/leve
r
systems to the rear wheels. These parts are designed
to obtain sufficient braking force even when parking on
slopes. W hen the parking brake is set, or when the
ignition SW is in the “ON” position, the brake warning
light illuminates. The rear wheel parking brake is a
leading-trailing brake (mechanical inside expansion
type) built in the rear drum brake. Parking brake
adjustment is made through the adjusting hole (bored
through back plate). Parking brake lever stroke should
be adjusted to 8 −14 notches with 294N (30 kg / 66 lb)
(bench seat) or 6 −9 notches with 294N (30 kg / 66 lb)
(bucket seat). Refer to “Parking Brake Adjustment” in
this section.

Inspection and Repair
Brake Lining Inspection
Check the shoe assemblies for wear by removing the
brake drum.
Replace the shoe assemblies if the lining thickness is
less than 1.0 mm (0.039 in).
Minimum limit: 1.0 mm (0.039 in)

Parking Brake Adjustment
NOTE: All brakes are self-adjusting. Brakes are
adjusted by repeated stepping on the brake pedal.
(After stepping on the pedal and releasing it, the rea
r
brake auto-adjuster produces a clicking sound. The
same operation should be repeated until the sound
disappears.)
Take the following steps after overhauling the rea
r
brake assembly.
1. Move the parking brake lever to its fully released position.
2. Parking brake cable must be loosened sufficiently.
(Loosen the adjust nut.)
3. Repeat stepping on the brake pedal firmly, and releasing it until the clicking sound can no longe
r
be heard.
If the difference between the brake drum inside
diameter and the brake shoes external diameter is
adjusted to be 0.4 mm (0.0157 in), the number o
f
times for depressing the brake pedal can be
reduced.

4. Remove the drum. Measure the brake drum inside
diameter and the brake shoes external diameter.
Total shoe clearance: 0.4 mm (0.0157 in)
If incorrect, readjust the brake shoe clearance.
5. Rotate the adjust nut of hand brake lever until all slack disappears from the cable. Set the adjust
nut.
6. After the rear brake shoe/drum gap has been adjusted, perform parking brake cable adjustment.
7. Turn the adjusting nut so that the parking brake lever travels 6 −9 notches (Bucket Seat) or 8 −14
notches (Bench Seat) when pulled up with a force
of 294 N (30 kg/66 lb).
8. Make sure there is no brake dragging.

ENGINE COOLING 6B – 17
Inspection and Repair
Make the necessary adjustments, repairs, and part
replacements if excessive wear or damage is discovered
during inspection.


Radiator Cap
Measure the valve opening pressure of the pressurizing valve
with a radiator filler cap tester.
Replace the cap if the valve opening pressure is outside the
standard range.
Valve opening pressure kPa (psi) 93.3
∼
∼∼
∼122.7 (13.5
∼
∼∼
∼17.8)
Cap tester: 5–8840–0277–0
Adapter: 5–8840–2603–0
Check the condition of the vacuum valve in the center of the
valve seat side of the cap. If considerable rust or dirt is found,
or if the valve seat cannot be moved by hand, clean or replace
the cap.

Radiator Core
1. A bent fin may result in reduced ventilation and overheating
may occur. All bent fins must be straightened. Pay close
attention to the base of the fin when it is being straightened.
2. Remove all dust, bugs and other foreign material.

Flushing the Radiator
Thoroughly wash the inside of the radiator and the engine
coolant passages with cold water and mild detergent. Remove
all signs of scale and rust.

Cooling System Leakage Check
Use a radiator cap tester to force air into the radiator through
the filler neck at the specified pressure of 196 kPa (28.5 psi)
with a cap tester:
• Leakage from the radiator
• Leakage from the coolant pump
• Leakage from the water hoses

Repair of the seat surface
• Remove carbon from the surface of the valve
insert seat.
• Use a seat cutter to minimize the scratch and
other roughness (15/45/75 degree-blade), thereb
y
returning the contact width to the standard value.







LNW 21BSH018201
Note:
Remove only scratches and roughness, and do not cut
the surface too much.
Use the free adjustment valve cutter pilot.
Do not let the valve cutter pilot waver inside the valve
guide.

Valve Seat Angle Degree

• Attach compound in the valve insert seat.
• Insert the valve into the valve guide.
•
Attach compound on the valve seat surface, rotate
the valve and hit it lightly to grind it, and confirm
that it has even contact all round.
Note:
Remove compound completely after grinding.
