Check that the rivets in the upper part of brake pedal are not
deformed.

Make sure sub bracket and slide plate are at least 4 mm (0.16
in) apart.

Check brake pedal for bend, damage, and cracks on the welded
parts. Replace the applicable part if a failure is detected.

Check clevis pin and resin stopper for damage and deformation.
If a failure is detected, replace clevis pin.

INSTALLATION
1. Loosen lock nut to adjust input rod length so that the length B (in
the figure) satisfies the specified value.
2. After adjusting “B”, temporarily tighten lock nut to install booster
assembly to the vehicle. At this time, make sure to install a gas-
ket between booster assembly and the dash panel.

Refer to BR-11, "
Hydraulic Circuit" .
6. Install master cylinder to booster assembly. Refer to BR-16, "
Removal and Installation" .
7. Adjust the height and play of brake pedal.
8. Tighten lock nut of input rod to the specified torque.
9. Refill new brake fluid and bleed air. Refer to BR-10, "

Use pliers in the locations where plate pliers A cannot be
used.
5. Make sure that the rim is completely crimped down.
6. Confirm that there is no leakage.
Refer to CO-20, "
INSPECTION" .
INSPECTION
1. Apply pressure with radiator cap tester adapter (SST) and radia-
tor cap tester (commercial service tool).
WARNING:
To prevent the risk of the hose coming undone while under
pressure, securely fasten it down with a hose clamp.
CAUTION:
Attach a hose to A/T fluid cooler to seal its inlet and outlet.
2. Check for leakage by soaking radiator in water container with
the testing pressure applied.

provide used radiator and connect it to tested radiator using
radiator hoses as shown in the figure.
NOTE:
The used radiator should be tested beforehand to confirm it
has no leakage. If used one is not available, it is possible to
use new service part as a radiator testing tool.

To prevent the risk of hose coming undone while under pressure, securely fasten it down with
hose clamp.

1. Start engine and warm it up to normal operating temperature.
2. Set voltmeter probes between ECM terminal 35 [HO2S1 (B1) signal] or 16 [HO2S1 (B2) signal] and
ground.
3. Check the following with engine speed held at 2,000 rpm con-
stant under no load.

The voltage fluctuates between 0 to 0.3V and 0.6 to 1.0V
more than 5 times within 10 seconds.

The maximum voltage is over 0.6V at least one time.

The minimum voltage is below 0.3V at least one time.

The voltage never exceeds 1.0V.
1 time: 0 - 0.3V → 0.6 - 1.0V → 0 - 0.3V
