BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air is suspected in
the brake lines, bleed the air from the system.
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 was disassembled or if the reservoir be-
comes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
SST 09751±36011
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plug with your finger, and release the
brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. BLEED BRAKE LINE
(a) Connect the vinyl tube to the 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.
Torque: 11 N´m (110 kgf´cm, 8 ft´lbf)
(d) Repeat (b) and (c) until all the air in the fluid has been bled
out.

(e) Repeat the procedure on the previous page to bleed the
air out of brake line for each wheel.
4. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3

ON±VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
151.1 ± 165.1 mm (5.949 ± 6.500 in.)
NOTICE:
Do not adjust the pedal height. Doing so by changing the
push rod length of the brake booster will structurally
change the pedal ratio.
If the pedal height is incorrect, check that there is no damage
in brake pedal, brake pedal lever, brake pedal bracket and dash
panel.
Even if there is damage, there is no problem if the
reserve distance is within the standard value.
If necessary, replace them.
2. IF NECESSARY, ADJUST STOP LIGHT SWITCH
(a) Remove the front door scuff plate, cowl side trim, side
panel, lower finish panel and No. 2 heater to register duct
(See page BO±89).
(b) Loosen the stop light switch lock nut.
(c) Push the brake pedal in 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.
(d) Push the brake pedal in 5 ±15 mm (0.20 ± 0.59 in.), check
that the stop light lights up.
(e) Install the No. 2 heater to register duct, lower finish panel,
side panel, cowl side trim and front door scuff plate (See
page BO±89).
3. CHECK PEDAL FREE PLAY
(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 second point of resis-
tance begins to be felt, then measure the distance as
shown in the illustration.
Pedal free play: 1 ± 6 mm (0.04 ± 0.24 in.)
HINT:
The free play to the first point of resistance is due to the play
between the clevis and pin. It is 1 ± 3 mm (0.04 ± 0.12 in.) at the
pedal.
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 ± 2.4 mm (0.020 ± 0.095 in.)

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 from asphalt sheet at 490 N
(50 kgf, 110.2 lbf): More than 95 mm (3.74 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

ON±VEHICLE INSPECTION
1. CHECK PARKING BRAKE PEDAL TRAVEL
Depress the parking brake pedal all the way and count the num-
ber of clicks.
Parking brake pedal travel at 300 N (31 kgf, 67 lbf):
6 ± 9 clicks
If incorrect, adjust the parking brake.
2. IF NECESSARY, ADJUST PARKING BRAKE PEDAL
TRAVEL
HINT:
Before adjusting the parking brake, make sure that the rear
brake shoe clearance has been adjusted. For shoe clearance
adjustment, see step 1 on page BR±47.
(a) Remove the front door scuff plate, cowl side trim board,
side panel, lower finish panel and No. 2 heater to register
duct (See page BO±89).
(b) Loosen the lock nut and turn the adjusting nut until the
pedal travel is correct.
(c) Tighten the lock nut.
Torque: 5.4 N´m (55 kgf´cm, 48 in.´lbf)
(d) Install the No. 2 heater to register duct, lower finish panel,
side panel, cowl side trim and front door scuff plate.
