Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Release the parking brake to avoid an incorrect measurement.
2. Check the toe.
 If adjustment is required, go to step 3.
 If no adjustment is required, go to turning angleinspection.
3. Hold the adjusting bolt (A) on the trailing arm (B), and loosen the self-locking nut (C).
4. Replace the self-locking nut with a new one, and lightly tighten it.
NOTE: Always use a new self-locking nut whenever it has been tightened to the specified torque.
 Reassemble the adjusting bolt and the adjusting cam plate with the eccentric facing up.
5. Adjust the rear toe by turning the adjusting bolt until the toe is correct.
6. Tighten the self-locking nut to the specified torque value while holding the adjusting bolt. Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Turn the wheel right and left while applying the brake, and measure the turning angle of both
wheels.
2. If the measurement is not within the specifications, even up both sides of the tie-rod threaded section
length while adjusting the front toe. If it is correct,
but the turning angle is not within the
specifications, check for bent or damaged
suspension components.

during reassembly (see step 5 on page 19-175).
4. Remove the parking brake cable mounting bolt (D) from the Knuckle. 5. Place a floor jack under the tra
iling arm to support
it.
NOTE: Do not place the jack against the plate
section of the lower arm. Be careful not to damage
any suspension components.
6. Remove the upper arm mounting bolt (A), and disconnect the upper arm (B) from the knuckle.
NOTE: Use the new upper arm mounting bolt
during reassembly.

5. Note the tire pressure sensor(s) number by the indicated DTC.
21 No. 1
22 No. 2
23 No. 3
24 No. 4 6. Do the tire pressure sensor location procedure to
determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
7. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR TEMPERATURE in the TPMS DATA LIST with the

Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
If any other DTCs are indicated, troubleshoot
the appropriate DTC. If no DTC are indicated, the
system is OK at this time.

Brake System Test
19-4 Conventional Brake Components
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. With the ignition switch in LOCK (0), inspect theplay (A) at the pedal pad (B) by pushing the pedal
by hand. If the brake pedal free play is out of
specification, adjust the brake pedal position switch
(C). If the brake pedal free play is insufficient, it
may result in brake drag. 1. Pull the parking brake lever (A) with 196 N (20 kgf,
44 lbf) of force to fully apply the parking brake. The
parking brake lever should be locked within the
specified number of clicks.
2. If the number of lever clicks is not as specified, adjust the parking brake.
