ADJUSTMENT
1. Loosen the stop lamp switch and by turning it counterclockwise
by 45°.
2. Loosen lock nut (A) on the input rod, then turn input rod to adjust
the pedal to specified height, and tighten lock nut (A).
CAUTION:
Make sure the threaded end of the input rod stays inside the
clevis.
3. With the pedal pulled and held by hand, press the stop lamp
switch and until its threaded end contacts the stopper.
4. With the threaded end of the stop lamp switch and contacting
the stopper, turn the switch clockwise by 45°to secure.
CAUTION:
Make sure that the clearance (C) between the bracket and
threaded end of the stop lamp switch and are within the
standard.
5. Check the pedal play.
CAUTION:
Make sure that the stop lamp goes off when the pedal is
released.
6. Start the engine to check the brake pedal depressed height.

INSPECTION AFTER REMOVAL
lCheck brake pedal upper rivet for deformation.
lMake sure that the lapping length of sub-bracket and slide plate
is at least 4 mm (0.16 in).
lCheck brake pedal for bend, damage, and cracks on the welded
parts.
lReplace brake pedal assembly if any non-standard condition is
detected.
lCheck clevis pin and plastic stopper for damage and deforma-
tion. Replace clevis pin if there are.
INSTALLATION
Installation is in the reverse order of the removal. Tightening torques for brake pedal assembly mounting nut
and bolt are referred toBR-8, "
COMPONENTS". Tightening torque for lock nut (A) is referred to Refer toBR-
7, "ADJUSTMENT".
lAfter installing the brake pedal assembly to the vehicle, adjust the brake pedal. Refer toBR-6, "Inspection

PFP:KN100
On-board InspectionEFS005SI
CHECKING BRAKE FLUID LEVEL
lMake sure the fluid level in the tank is within the standard
(between MAX and MIN lines).
lVisually check around the reservoir tank for fluid leakage.
lIf fluid level is excessively low, check brake system for fluid leak-
age.
lRelease parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillEFS005SJ
CAUTION:
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe off them and wash it away with water.
lBefore working, disconnect connector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the pedal. Repeat the same work for each
wheel.
5. Bleed air. Refer toBR-11, "
Bleeding Brake System".

lBefore working, disconnect electrical connector of ABS actuator and electric unit (control unit) or
the battery cable from the negative terminal.
LHD MODEL
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 3, 4 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer toBR-24, "
Components"(front disc brake),BR-30, "Com-
ponents"(rear drum brake).
6. From the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from the
front left, rear left, and front right brake, in that order.

CAUTION:
lAll brake tubes and hoses must be free from excessive bending, twisting and pulling.
lMake sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
lBrake tube and hose is an important safety part. Always disassemble the parts and retighten their
fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe off them and wash it away with water.
lDo not bend or twist brake hose sharply, or strongly pull it.
lCover the open end of brake tube and hoses when disconnecting to prevent entrance of dirt.
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.

CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
