BRAKE PEDAL

BRAKE PEDALPFP:46501
On-Vehicle Inspection and AdjustmentEFS000C1
Adjust clearance between dash panel and brake pedal upper surface
to the following dimensions.
1. Loosen stop lamp switch by rotating it counter-clockwise by 45°.
2. Loosen input rod lock nut (A), then rotate input rod, set pedal to
the specified height, and tighten lock nut (A).
CAUTION:
Confirm threaded end of input rod remains inside the cle-
vis.
3. Pull pedal by hand and hold it. Press stop lamp switch until its
threaded end contacts the stopper rubber.
4. While holding it against the stopper rubber, turn the switch clock-
wise by 45° and secure it.
CAUTION:
Be sure stopper rubber to stop lamp switch screw threaded
end gap (C) is within the specifications.
5. Check pedal free play.
CAUTION:
Be sure stop lamps go off when pedal is released.
6. Start engine and check brake pedal depressed height.

Removal and InstallationEFS000C2
REMOVAL
Be careful not to deform brake tube.
1. Remove instrument lower driver panel. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
2. Remove steering column assembly from steering member. Refer to PS-10, "
STEERING COLUMN" .
3. Remove stop lamp switch from brake pedal assembly.
4. Remove snap pin and clevis pin from brake booster clevis.
5. Remove brake pedal assembly mounting nuts. Pull brake booster toward engine compartment to the
extent that does not deform brake tube.
6. Remove brake booster clevis from input rod.
7. Remove the mounting bolts from the bracket, and remove the pedal assembly from the vehicle.
INSPECTION AFTER REMOVAL
Check brake pedal for the following.

Bent brake pedal

Deformed clevis pin

Cracks in welded area

Cracked or deformed clevis pin stopper
INSTALLATION
Install in reverse order of removal. Be careful of the following:

Adjust brake pedal assembly after installing it.
1. Snap pin 2. Stop lamp switch 3. Clip
4. Clevis pin 5. Brake pedal assembly

BRAKE FLUID

BRAKE FLUIDPFP:KN100
Checking Brake Fluid Level EFS000C5

Confirm reservoir tank fluid level is within the specifications
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Always keep fluid level higher than minimum line on reservoir tank.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away water immediately.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while
depressing brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

3. Tighten flare nut by using a flare nut wrench with the specified
torque.
4. Refill brake fluid until new brake fluid comes out of each bleed
valve.
5. Afterwards, bleed air.
InspectionEFS000C9
CAUTION:
If any leaks on joints, retighten it. Replace any damaged parts.
1. Check hose, tube, and joints for fluid leaks, damage, twist, deformation, contact with other parts, and
loose connections.
2. Run engine. Depress brake pedal and hold it for approximately 5 seconds while checking each part for
leaks.: 15 - 17 N·m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)

BRAKE BOOSTERPFP:47200
On-Vehicle Inspection and ServiceEFS000CC
FUNCTION INSPECTION
With engine stopped, discharge stored vacuum by depressing brake
pedal several times at 5 second intervals. With brake pedal fully
depressed, start the engine. Confirm that clearance between brake
pedal and floor panel decreases when engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION

Run engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress brake pedal several
times with normal force to discharge the stored vacuum. Con-
firm that clearance between brake pedal and floor panel gradu-
ally increases as the brake pedal is depressed.

Run engine. Depress and hold brake pedal then stop engine.
Keep brake pedal depressed for 30 seconds or more and make
sure the pedal stroke does not change.
Removal and InstallationEFS000CD
REMOVAL
CAUTION:

Be careful not to deform or bend brake piping while remov-
ing and installing brake booster.

Replace clevis pin if it is damaged.

Be careful not to damage brake booster stud bolt threads. If
brake booster is tilted or inclined during installation, dash
panel may damage the threads.

Be sure to install check valve in the correct orientation.
1. Remove vacuum piping from the brake booster.
2. Remove master cylinder.
3. Remove snap pin and clevis pin on the clevis of input rod. Remove input rod from the brake pedal.
4. Remove brake booster and brake pedal assembly mounting nuts.
5. Remove booster assembly from the engine compartment.

VACUUM LINES


Insert the vacuum hose at least 24 mm (0.94 in).

Never use lubricating oil during assembly.
InspectionEFS000CF
VISUAL INSPECTION
Check for improper assembly, damage and aging.
CHECK VALVE INSPECTION
Airtightness Inspection
Use a hand-held vacuum pump to check.
SBR225B
When connected to booster side (1):
Vacuum decrease should be within 1.3 kPa
(10 mmHg, 0.39 inHg) for 15 seconds under
a vacuum of –66.7 kPa (–500 mmHg, –19.69
inHg)
When connected to engine side (2):
No vacuum will be applied
