5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant and
engine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the
regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.
Sensor spring length ªLº
Hardtop: 201 mm (7.913 in)
Wagon: 197.5 mm (7.776 in)
NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805
kPa (48.1 bar, 49 kg/cm
2, 697 psi) is obtained (at the front axle
pressure gauge) and an output pressure of 1,736 - 2,501 kPa
(18 - 26 bar, 17.7 - 25.5 kg/cm
2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under
b) until the output pressure measured is within the specified range.

Removal
CAUTION:
Be careful not to splash brake fluid on painted areas; it may
cause paint damage. If brake fluid is splashed on painted
areas, wash it away with water immediately. DO NOT RUB.
1. Connect a vinyl tube to air bleeder valve.
2. Drain brake fluid from each air bleeder valve, depressing brake
pedal to empty fluid from master cylinder.
3. Remove brake pipe flare nuts.
4. Remove master cylinder mounting nuts.
5. Remove protector of master cylinder, and avoid scratching the
surface of master cylinder during removal.
CAUTION:
Do not disassemble master cylinder.
NOTE:
If it is necessary to change the brake fluid reservoir, remove it
as shown in the illustration on the left, while holding the seals
with one hand.
It is not necessary to replace the seals if they are in a good
condition.
Installation
CAUTION:
IRefill with new brake fluid ªDOT 4º.
INever reuse drained brake fluid.
1. Place master cylinder onto brake booster and secure mounting
nuts lightly.
2. Fit flare nuts to master cylinder.
3. Tighten mounting nuts.
