Rapid brake pad wear, vehicle vibration
(after a long drive), or high, hard brake pedal

YES

Symptom Troubleshooting

NOTE: Make sure that the caliper pins are installed
correctly.
The upper and lower caliper pins are different. If the top
and bottom caliper pins are installed in the wrong
location, it will cause uneven tire wear, vibration, and or
uneven or rapid pad wear. For proper caliper pin
location (see page 19-16).

1. Drive the vehicle until the brakes drag or until the

pedal is high and hard. This can take 20 or more
brake pedal applications during an extended test
drive.

2. With the engine running, raise the vehicle on a lift,

and spin all four wheels by hand.

Go to step 3.

Look for other causes of the pad wear, high

pedal, or vehicle vibration.

3. Turn the engine off, pump the brake pedal to

deplete the vacuum in the brake booster, and then
spin the wheels again to check for brake drag.

Go to step 4.

Replace the brake booster (see page 19-20).

4. Without removing the brake lines, unbolt and

separate the master cylinder from the booster, then
spin the wheels to check for brake drag.

Go to step 5.

Check the brake pedal position switch

adjustment and pedal free play (see page 19-6).

5. Loosen the hydraulic lines at the master cylinder,

then spin the wheels to check for brake drag.

Go to step 6.

Replace the master cylinder (see page 19-18).

6. Loosen the bleed screws at each caliper, then spin

the wheels to check for brake drag.

Disassemble and repair the caliper on the

wheel(s) with brake drag.

Look for and replace any damaged brake lines.

If all brake lines are OK, replace the VSA
modulator-control unit (see page 19-94).

Pedal Height

Standard pedal height (with carpet removed):

155 mm (6 1/8 in.)

Brake Pedal Position Switch Clearance

Conventional Brake Components

Brake Pedal and Brake Pedal Position Switch Adjustment

0.7 mm (0.03 in.)

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

insulator. Lift up the insulator cutout and measure
the pedal height (B) at the middle of the left side
center of the pedal pad (C) to the floor.

3. Lift up on the brake pedal by hand. Push in the

brake pedal position switch until its plunger is fully
pressed (the threaded end (A) touches the pad (B)
on the pedal arm). Then back off the switch 3/4 turn
to make 0.7 mm (0.03 in.) of clearance between the
threaded end and pad. Tighten the locknut securely.
Connect the brake pedal position switch connector.
Make sure the brake lights go off when the pedal is
released.

Parking Brake Inspection and
Adjustment

Pressed with
294 N·m
(30 kgf, 66 lbf)

1. With the engine off, inspect the pedal free play (A)

on the pedal pad (B) by pushing the pedal by hand.

2. If the 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
excessive brake drag.

1. Press the parking brake pedal (A) with 294 N (30 kgf,

66 lbf) of force. The parking brake pedal should
travel within the specified number of clicks (B).

If the number of pedal clicks is excessive, adjust the
parking brake.

1. Raise the rear of the vehicle, and support it with

safety stands in the proper locations (see page
1-10).

2. Tighten the adjusting nut (A) until the parking

brakes drag slightly when the rear wheels are
turned.

3. Back off the adjusting nut in half-turn increments,

and check for proper adjustment (10 to 12 clicks) at
a pedal force of 294 N (30 kgf, 66 lbf).
