− BRAKEBRAKE FLUID
1996 RAV4 (RM447U)
BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or air in the brake lines
is suspected, 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
Fluid: SAEJ1703 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 master cylinder of the air.
(a) Disconnect the brake lines from the master cylinder.
(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 or wheel cylinder.
(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 of the
air for each wheel.

− BRAKEBRAKE PEDAL
1996 RAV4 (RM447U)
BRAKE PEDAL
ON−VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from asphalt sheet:
157.1 − 167.1 mm (6.185 − 6.579 in.)
If the pedal height is incorrect, adjust it.
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 with the pedal stopper.
(g) Turn the stop light switch back one turn.
(h) Check the clearance (A) between 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) After adjusting the pedal height, check the pedal freeplay.
HINT:
If clearance (A) between the stop light switch and the brake
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 resistance begins to
be felt, then measure the distance, as shown.
Pedal freeplay: 1 − 6 mm (0.04 − 0.24 in.)

BR−7
1996 RAV4 (RM447U)
HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis and pin. It is 1 − 3 mm (0.04 − 0.12 in.) on the
pedal.
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
4. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake.
(b) 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 75 mm (2.95 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

PARKING BRAKE LEVER
ON−VEHICLE INSPECTION
1. CHECK PARKING BRAKE LEVER TRAVEL
Pull the parking brake lever all the way up, and count the num-
ber of clicks.
Parking brake lever travel at 196 N (20 kgf, 44 lbf):
5 − 8 clicks
If incorrect, adjust the parking brake.
2. IF NECESSARY, ADJUST PARKING BRAKE
HINT:
Before adjusting the parking brake, make sure that the rear
brake shoe clearance has been adjusted. For shoe clearance
adjustment, see page BR−33.
(a) Remove the rear console box.
(b) Loosen the lock nut and turn the adjusting nut until the le-
ver travel is correct.
(c) Tighten the lock nut.
Torque: 5.4 N·m (55 kgf·cm, 48 in.·lbf)
(d) Install the rear console box.
