Inspection and adjustment
INSTALLATION POSITION OF PUSH ROD
Install push rod clevis (1) so that measurement “a” is obtained
and torque nut (2) to specification.
Tightening torque
Booster clevis nut
(a) : 25 N·m (2.5 kg-m, 18.0 Ib-ft)
Distance “a” between center of booster clevis pin hole
and booster surface
Standard : 126.1 – 127.1 mm (4.96 - 5.00 in.)
1. Steering column
2. Push rod clevis
5. Clip
NOTE:
See NOTE at the beginning of this section.
Check length of push rod clevis and adjust clearance
between booster piston rod and master cylinder pis-
ton. Refer to “Brake Booster Inspection and Adjust-
ment” in this section
Apply silicone grease to master cylinder piston.

CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON
The length of booster piston rod (1) is adjusted to provide speci-
fied clearance “a” between piston rod end and master cylinder
piston (2).
Before measuring clearance, push piston rod several times
so as to make sure reaction disc is in place.
Keep inside of booster at atmospheric pressure for measure-
ment.
Remove piston (push) rod seal from booster, if equipped.
1) Set special tool (E) on master cylinder (1) and push pin (3)
until contacts piston (2).
Special tool
(E): 09950-96010
2) Turn special tool upside down and place it on booster (1).
Adjust booster piston rod (2) length until rod end contacts pin
head (3).
Special tool
(E): 09950-96010
Clearance “b” (between special tool and piston rod)
0 mm (0 in.)
3) Adjust clearance by turning adjusting screw of piston rod.
Special tool
(F) : 09952-16010
NOTE:
Take measurement with booster set vertically or piston
rod supported with screw driver or such so as to set rod
at the center.

REMOVAL
1) Raise, suitably support vehicle. Remove wheel if necessary.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose and pipe.
INSTALLATION
1) Install brake hose and pipe by reversing removal procedure, noting the following points.
For installation, make sure that steering wheel is in straightforward position and hose has no twist or kink.
Check to make sure that hose doesn’t contact any part of suspension, both in extreme right and extreme left
turn conditions. If it does at any point, remove and correct. Fill and maintain brake fluid level in reservoir.
Bleed brake system.
2) Perform brake test and check installed part for fluid leakage.
