INSPECTION
CAUTION:
Replace the seat belt assembly (outer belt, inner belt, bolts,
nuts or sill −bar) if it has been used in a severe impact. The
entire assembly should be replaced even if damage is not
obvious.
1. All seat belts: RUNNING TEST (IN SAFE AREA)
(a) Fasten the front seat belts.
(b) Drive the car at 10 mph (16 km/h) and make a very hard stop.
Check that the belt locks and cannot be extended at this
time.
HINT:
Conduct this test in a safe area. If the belt does not lock, remove
the belt mechanism assembly and conduct the following static
check. Also, whenever installing a new belt assembly, verify the
proper operation before installation.
2. Driver ’s seat belt (ELR): STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
(c) Tilt the retractor slowly.
(d) Make sure that the belt can be pulled out at a tilt of 15 de-
grees or less, and cannot be pulled out at over 45 degrees
of tilt.
If a problem is found, replace the assembly.
3. Except driver’s seat belt (ALR/ELR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
(c) Pull out the whole belt and measure the length of the whole belt.
Then retract the belt slightly and pull it out again.
(d) Make sure that the belt cannot be extended further.
If a problem is found, replace the assembly.
(e) Retract the whole belt, then pull it out to the full length mi-
nus 200 mm (7.87 in.).
(f) Tilt the retractor slowly.
(g) Make sure that the belt can be pulled out at a tilt of 15 de-
grees or less, and cannot be pulled out at over 45 degrees
of tilt.
If a problem is found, replace the assembly.

BRAKE SYSTEM
GENERAL DESCRIPTION
Care must be taken to replace each part properly as it could affect the perfo\
rmance of the brake
system and result in a driving hazard. Replace the parts with parts of the same part number or
equivalent.
It is very important to keep parts and the area clean when repairing the\
brake system.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.

BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air is suspected in
the brake lines, bleed the system of air.
NOTICE:
Do not let brake fluid remain on a painted surface. Wash it
off immediately.
1. FILL BRAKE RESERVOIR WITH BRAKE FLUID
Check the fluid level in the reservoir after bleeding each wheel.
Add fluid, if necessary. Fluid: SAE J1703 or FMVSS No.116 DOT3
2. BLEED MASTER CYLINDER
HINT:
If the master cylinder has been disassembled or if the reservoir
becomes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plugs with your fingers, and release the brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. CONNECT VINYL TUBE TO BRA KE CALIPER BLEED-
ER PLUG
Insert other end of the tube in a half −full container of brake fluid.
NOTICE:
Begin bleeding air from the brake caliper with the longest
hydraulic line.
4. BLEED BRAKE LINE
(a) Slowly depress the brake pedal several times.

(b) While an assistant depresses the pedal, loosen the
bleeder plug until fluid starts to run out. Then tighten the
bleeder plug.
(c) Repeat this procedure until there are no more air bubbles
in the fluid.

BRAKE PEDAL
ON−VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
167.5 − 177.5 mm (6.594 − 6.988 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Disconnect the connector from the stop light switch.
(b) Loosen the stop light switch lock nut and remove the stop
light switch.
(c) Loosen the push rod lock nut.
(d) Adjust the pedal height by turning the pedal push rod.
(e) Tighten the push rod lock nut. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(f) Install the stop light switch and turn it until it lightly con-
tacts the pedal stopper.
(g) Turn the stop light switch back one turn.
(h) Check the clearance (A) between the stop light switch and pedal.
Clearance: 0.5 − 2.4 mm (0.020 − 0.094 in.)
(i) Tighten the stop light switch lock nut.
(j) Connect the connector to the stop light switch.
(k) Check that the stop lights come on when the brake pedal
is depressed, and go off when the brake pedal is re-
leased.
(l) earance (A) between the stop light switch and the pedal
stopper has been adjusted correctly, the pedal freeplay
will meet the specifications.
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the beginning of the se- cond resistance is felt. Measure the distance.
Pedal freeplay: 3 − 6 mm (0.12 − 0.24 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 3 − 6 mm (0.12 − 0.24 in.)
at the pedal.

If incorrect, check the stop light switch clearance.
If the clearance is OK, then troubleshoot the brake system.
4. CHECK PEDAL RESERVE DISTANCE
Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance, ’a’, at 490 N (50 kgf, 110.2lbf):
More than 68 mm (2.68 in.)
If the reserve distance incorrect, troubleshoot the brake sys-
tem.
