Check of pressure of liquid (if the car is equipped with LSPV)

Check procedure for assembly of LSPV is described below.

 PERFORMANCE ORDER

  1. Before carrying out check, be convinced of the following:
    • The fuel tank is completely filled with fuel.
    • The vehicle is equipped with a spare tire, the tool, a jack and the jack handle.
  2. Establish a vehicle on an equal floor and establish loading about 200 kg (441 pounds) (2) on a back part of the case so that the back shaft weighed 800 kg (1764 pounds). Weight of a back shaft of "L": 800 kg (1764 pounds).
  3. Establish the special tool on a forward and back brake.

The special tool should be connected with sapuny a forward brake (from the driver) and a back brake.

  • Special tool of a forward brake:
    • (A): 9956-02310
    • (B): 09952-46510 (the adaptation for a support of a brake of the car with SUMITOMO ELECTRIC brake)
    • (C): 55473-82030 (the spuskny stopper of the valve of a stravlivaniye of air (1) is delivered as the spare part)
  • Back brake
    • (A): 09956-02310
    • (B): 09952-36310 (the adaptation for a stopper of the valve of a stravlivaniye of air with diameter of a carving of 7 mm) or 09952-46510 (the adaptation for a stopper of the valve of a stravlivaniye of air with diameter of a carving of 8 mm)
    • (C): 55473-82030 (the spuskny stopper of the valve of a stravlivaniye of air is delivered as the spare part)
  • Instead of the adaptation for diameter of a carving of 10 mm (3) to the special tool (A) the special tool (B) is used. Therefore remove the adaptation from (A) and establish (B).
  • For a vehicle with a support of a brake of TOKICO, use the adaptation which is switched on in the special tool (A).
  • For definition such as a support of a brake address to Head Forward brakes.

  1. Gradually press the brake lever, pressure of liquid in a forward brake does not become such, as shown below and then check the corresponding pressure of a back brake. It should correspond to the specification below.

Pressure of a back brake with enclosed load of 8000 kPas (80 kg/cm2, 1,138 psi) on a forward brake

Forward brake

Back brake

8,000 kPas of 80 kg/cm2 of 1,138 psi

3-door or model with harmonious top

6,000 — 7,300 kPas

60 — 73 kg/c¼2

853 — 1,038 psi

The 5-door

4,500 — 7,300 kPas

45 — 73 kg/c¼2

640 — 1,038 psi

After that put pressure of 100 kg/cm2 upon a forward brake and check that pressure of a back brake corresponds to the specification below.

Forward brake

Back brake

10,000 kPas of 100 kg/c¼2 1,422 of psi

3-door or model with harmonious top

6,500 — 8,000 kPas

65 — 80 kg/cm2

924 — 1,138 psi

The 5-door

5,000 — 8,000 kPas

50 — 80 kg/cm2

711 — 1,138 psi


  1. If pressure of a back brake does not correspond to the specification, adjust it having changed the provision of a rack (3) as follows.
    • If pressure of a back brake is higher specified, move a rack (3) in the direction "a", and if below, in the direction "b".
    • Repeat steps 3-5 while pressure of a back brake will not correspond to the specification.
    • After adjustment, tighten a bolt with an inhaling torque according to specified in the specification. Inhaling torque: bolt of a rack of LSPV (a): 23 N • m (2.3 kg-m, 17.0 pounds on foot).
  1. Disconnect the brake highway (2) (connecting the second contour of the main cylinder and 4-foreign connection) from the main cylinder (1). Tighten a cap (the special tool) main cylinder. Press the brake lever. If pressure of a back brake of 95-100 kg/cm2 when pressure of a forward brake of 100 kg/cm2, it means that forward failure-safe system works properly. Special tool: (A) — 09956-02210.

Forward brake

Back brake

10,000 kPas of 100 kg/cm2 of 1,422 psi

9,500 — 10,000 kPas

95 — 100 kg/cm2

1,350 — 1,422 psi

  1. On termination of check of pressure of liquid, pit air from brake system and execute check of brakes.
