Removal
1. Remove speed sensor connector at connector
portion.
2. Remove sensor fixing bolt (4).
3. Remove cable fixing bolts and nut (4 ×2).
4. Disconnect the arrow mark locks of the cable clips.
5. Remove the speed sensor assembly.
Inspection and Repair
1. Check the speed sensor head for presence of
foreign materials; remove any dirt, etc.
2. Check the head for damage; replace speed senso
r
if necessary.
3. Check the speed sensor cable for short or open circuit, and replace with a new one if necessary.
To check for cable short or open, bend or stretch the cable while checking for continuity.

Operation
1) Outline
W hen the LSPV (Load Sensing Proportioning Valve) detects a change in load weight, the load sensing spring
stretches.
Its reaction force is transmitted to the bottom of the load sensing valve to secure an optimum rear wheel cylinde
r
fluid pressure break point in proportion to the actual load
weight.
Besides, if the front brake system should fail, the device is designed to prevent the master cylinder fluid pressure from
decreasing and to apply it directly to the rear wheel cylinde
r
to obtain a sufficient braking performance.

2) Bellow cutting point.
The Force (F) keeps the main piston (1) the rest position. The inlet pressure (A) and outlet pressure (B) are the same
as well as the inlet pressure (C) from front master cylinder.
The bypass piston (2) is kept on rest position by equilibrium
of the pressures (A) and (C) and the bypass spring load (3).

RTW 35CSH001201
3) Cutting point.
The cutting point is given by relation between force (F), that is the load applied by suspension of the vehicle and the
main piston area (1). The cutting point is achieved when the
force generated by hydraulic pressure is upper than the
force (F) given by the load suspension. The main piston (1)
moves from the rest position closing the valve. In this
moment the inlet pressure (A) is upper than the outlet
pressure (B). The bypass piston (2) continues on the rest
position by equilibrium of (A) and (C) pressure.

3) Rear wheel cylinder fluid pressure measurement
Step on the brake pedal until the fluid pressure of the front wheel cylinder gets to 9.8Mpa (100kg/cm
2), and
check the rear wheel cylinder fluid pressure. (Read the
value of the front wheel cylinder fluid pressure 2
seconds after the measurement. W hen measuring the
LSPV fluid pressure, keep the brake pedal pressed
down without stepping it down twice or releasing it.)
Rear W heel Cylinder Fluid Pressure MPa (kg/cm

2. Oil Pressure Adjustment
1) LSPV spring length adjustment
Loosen the adjust nut of the LSPV spring joint, and adjust the length of the LSPV spring.
W hen the oil pressure is insufficient, turn the adjust nut clockwise to extend the span “A”. W hen the oil pressure
is too high, turn the adjust nut counterclockwise to
reduce the span “A”.


2) After adjustment, tighten the lock nut securely.
Lock Nut Torque N⋅m (kgf ⋅m/lb ⋅ft)

27. After the bleeding operation is completed on each individual
wheel, check the level of the brake fluid in the reservoir and
replenish up to the “MAX" level as necessary.
28. Attach the reservoir cap.
29. Stop the engine.

BRAKE LINE (HOSES AND PIPES)
• Inspect all hoses and pipes for wear, bending, chafing,
cracks, dents, or any other damage.
Make necessary correction or replace parts if these abnormal conditions are found through inspection.
• All hoses, pipes and joints can be damaged easily.
Do not allow the hose to become excessively twisted and bent when working with them, and pay special attention to
all the brake lines not to damage them when repairing o
r
replacing other parts (axle, suspension, etc).
• Inspection for leakage should be performed by depressing
the brake pedal fully.
If leakage is apparent at the circumference of joints, retighten or replace these parts.
This procedure must be performed whenever brake lines are installed.
• After disconnecting the hoses and pipes, cap or tape the
openings to prevent entry of foreign material.
