1. Before installing the tire pressure sensor, clean the
mating surfaces on the sensor and the wheel.
2. Install the tire pressure sensor (A) and the washer (B) to the wheel (C), and tighten the valve stem nut
(D) finger tight. Make sure the pressure sensor is
restingonthewheel.
NOTE: Install the tire pressure sensor so that
sensor housing surface (E) should not exceed
protrusion (F) of wheel to prevent the sensor
housing from being caught on the bead of the tire
when assembling the tire.
3. Tighten the valve stem nut to the specified torque while holding the tire pressure sensor.
NOTE: Do not use air or electric impact tools to tighten a valve stem nut.
 Do not twist the tire pressure sensor to adjust its position with the wheel, as this will damage or
deform the valve stem grommet. 4. Lube the tire bead sparingly with a paste-type tire
mounting lubricant, and position the wheel so the
tire machine (A) and tire iron (B) are next to the
valve stem (C) and will move away from it when
the machine starts. Then install the tire onto the
wheel.
5. With a dry air source, inflate the tire to 300 kPa (3.1 kgf/cm , 44 psi) to seat the tire bead to the rim,
then adjust the tire pressure (see page 18-5), then
install the valve stem cap.
NOTE: Make sure the tire bead is seated on both
sides of the rim uniformly.
6. Check and adjust the wheel balance, then install the wheels on the vehicle.
7. Remove the jack stands, and lower the vehicle. Torque the wheel nuts to specification.
8. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).

Brake System Inspection and Test
Inspect the brake system components listed. Repair or replace any parts that are leaking or damaged.










Master Cylinder Look for damage or signs of fluid leakage at:
Reservoir tank, subreservoir or master
cylinder body.
Lines, reservoir tank hose and grommets,
and their joints.
Between master cylinder and booster. Bulging seal at reservoir cap. This is a
sign of fluid contamination.
Brake Hoses Look for damage or signs of fluid leakage at: Line joints and banjo bolt connections.
Hoses and lines, also inspect for twisting or
damage. Bulging, twisted, or bent lines.
Caliper Look for damage or signs of fluid leakage at: Piston seal.
Banjo bolt connections.
Bleed screw. Seized or sticking caliper pins.
ABS or VSA
Modulator-control
Unit Look for damage or signs of fluid leakage at:
Line joints.
Modulator-control unit.
1. Set the parking brake, and start the engine, then turn off the A/C. Allow the engine to warm up to normal operating temperature (radiator fan comes on twice).
2. Attach a 50 mm (2 in.) piece of masking tape along the bottom of the steering wheel, and draw a horizontal reference mark across it.
3. With the transmission in neutral (M/T) or P or N (A/T), press and hold the brake pedal lightly (about the same pressure needed to keep an A/T-equipped vehicle from creeping), then release the parking brake.
4. While still holding the brake pedal, hook the end of the tape measure behind the brake pedal, then pull the tape up to the steering wheel. Note the measurement between the brake pedal and the reference mark on the steering
wheel.
5. Apply steady pressure to the brake pedal for 3 minutes.
6. Watch the tape measure.  If the measurement increases 10 mm (0.39 in.) or less, the master cylinder is OK.
 If the measurement increases more than 10 mm (0.39 in.), replace the master cylinder.

1. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no
longer touching the brake pedal.
2. Pull back the carpet, and find the cutout in the insulation. Measure the pedal height (B) at the
middle of the left side center of the pedal pad (C) to
the floor without the insulation. 3. Loosen the pushrod locknut (A), and screw the
pushrod (B) in or out with pliers until the standard
pedal height from the floor is reached. After
adjustment, tighten the locknut firmly. Do not
adjust the pedal height with the pushrod pressed.
4. Lift up on the brake pedal by hand. Push in the brake pedal position switch until its plunger is fully
pressed (threaded end (A) touching the pad (B) on
the pedal arm). Turn the switch 45 ° clockwise to
lock it. The gap between the brake pedal position
switch and the pad is automatically adjusted to
0.7mm(0.028in.)bylockingtheswitch.Makesure
the brake lights go off when the pedal is released.
5. Check the brake pedal free play.

1. Remove the center console panel (see page 20-92).
2. Release the parking brake lever fully.
3. Loosen the parking brake adjusting nut (A).
4. Raise the rear of the vehicle, and support it with safety stands in the proper locations (see page

contacts the stop pin (B).
NOTE: The lever will only contact the stop pin when
the parking brake adjusting nut is loosened.
7. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels.
8. Pull the parking brake lever 1 click.
9. Tighten the parking brake adjusting nut until the parking brakes drag slightly when the rear wheels
are turned.
10. Release the parking brake lever fully, and check that the parking brakes do not drag when the rear
wheels are turned. Readjust if necessary.
11. Make sure the parking brake lever is within the specified number of clicks (8 to 10 clicks).
12. Install the center console panel (see page 20-92).

Frequent inhalation of brake pad dust, regardless of
material composition, could be hazardous to your
health. Avoid breathing dust particles.
 Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum
cleaner.
1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
2. Remove the front wheels. 3. Check the thickness (A) of the inner pad (B) and the
outer pad (C). Do not include the thickness of the
backing plate.
4. If any part of the brake pad thickness is less than the service limit, replace the front brake pads as a
set.
5. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheels.

11. Install the brake caliper piston compressor tool (A)
on the caliper body (B).
12. Press in the piston with the brake caliper piston compressor tool so the caliper will fit over the
brake pads. Make sure the piston boot is in position
to prevent damaging it when pivoting the caliper
down.
NOTE: Be careful when pressing in the piston;
brake fluid might overflow from the master
cylinder’s reservoir. If brake fluid gets on any
painted surface, wash it off immediately with water.
13. Remove the brake caliper piston compressor tool. 14. Apply a thin coat of M-77 assembly paste (P/N
08798-9010) to the pad side of the shims (A), the
back of the brake pads (B), and the other areas
indicated by the arrows. Wipe excess assembly
paste off the pad shims and the brake pads friction
material. Keep grease and assembly paste off the
brake disc and the brake pads. Contaminated brake
disc or brake pads reduce stopping ability.
15. Install the brake pads and the pad shims correctly. Install the brake pad with the wear indicator (C) on
the upper inside. If you are reusing the brake pads,
always reinstall the brake pads in their original
positions to prevent a momentary loss of braking
efficiency.

Clean and lube if needed.
8. Inspect the brake disc for runout, thickness, parallelism (see page 19-19) and check for damage
and cracks.
9. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainer mating surface of the
