(l) Observe the procedure in step (k) and bleed left rear
brake line.
(m) Disconnect the actuator checker (SST) and sub-wire har-
ness (SST) from the actuator.
SST 09990-00150, 09990-00480
(n) Connect the 2 connectors to the hydraulic brake booster.
(o) Clear the DTC (See page DI-505).
4. BLEED BRAKE LINE
(a) Connect the vinyl tube to the brake caliper.
(b) Depress the brake pedal several times, then loosen the
bleeder plug with the pedal held down.
(c) At the point when fluid stops coming out, tighten the
bleeder plug, then release the brake pedal.
(d) Repeat (b) and (c) until all the air in the fluid has been bled
out.
(e) Repeat the above procedure to bleed the brake line for
each wheel.
Torque: 11 N´m (110 kgf´cm, 8 ft´lbf)
5. CHECK FLUID LEVEL IN RESERVOIR
(a) With the ignition switch OFF, depress the brake pedal
more than 40 times.
HINT:
When a pressure in power supply system is released, reaction
force becomes light and stroke becomes longer.
(b) Remove the reservoir cap. Add brake fluid up to the
ºMAXº line.
Fluid: SAE J1703 or FMVSS NO. 116 DOT3

ON-VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from asphalt sheet:
183.7 - 193.7 mm (7.232 - 7.626 in.)
If the pedal height is incorrect, adjust it.
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Remove the scuff plate, cowl side trim, lower No. 1 panel,
LH lower panel and No. 2 heater to register duct (See
page BO-81).
(b) Remove the steering wheel pad, steering wheel lower
No. 2 and No. 3 covers, steering wheel, combination
switch, column upper and lower covers, steering column
assembly and thrust stopper (See page SR-14 or
SR-29).
(c) Disconnect the connector from the stop light switch.
(d) Loosen the stop light switch lock nut and remove the stop
light switch.
(e) Loosen the push rod lock nut.
(f) Adjust the pedal height by turning the pedal push rod.
(g) Tighten the push rod lock nut.
Torque: 25 N´m (260 kgf´cm, 19 ft´lbf)
(h) Install the stop light switch.
(i) Connect the connector to the stop light switch.
(j) Push in the brake pedal 5 - 15 mm (0.20 - 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(k) After installation, push in the brake pedal 5 - 15 mm (0.20
- 0.59 in.), check that stop light lights up.
(l) After adjusting the pedal height, check the pedal freeplay.
(m) Install the thrust stopper, steering column assembly, col-
umn upper and lower covers, combination switch, steer-
ing wheel, steering wheel lower No. 2 and No. 3 covers,
and steering wheel pad (See page SR-14 or SR-29).
(n) Install the No. 2 heater to register duct, LH lower panel,
lower No. 1 panel, cowl side trim and scuff plate (See
page BO-81).
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal more than
40 times until there is no more pressure left in the booster.
(b) Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance, as
shown.
Pedal freeplay: 1.0 - 6.0 mm (0.039 - 0.236 in.)

If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance: 1.9 mm (0.075 in.)
HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis, pedal link and pin. It is 1.0 - 6.0 mm (0.039 -
0.236 in.) on the pedal.
4. CHECK PEDAL RESERVE DISTANCE
(a) Remove the floor carpet.
(b) Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance at 490 N (50 kgf, 110.1 lbf):
More than 116 mm (4.57 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.
