upper surface of
the pedal pad and verify that it is as specified.

- If not within the specification, replace the pedal component.
Pedal height (reference value)
Pedal play inspection
1. Pump the pedal several times to release the vacuum in the power brake
unit.
2. Gently depress the pedal by hand and measure the pedal play.
- If not within the specification, inspect the wear of the clevis pin.
Replace it if
there is any malfunction.
Standard pedal play
- 2.6-4.7 mm {0.11-0.18 in}
NOTE:
- If there is no malfunction in the clevis pin, there is a possibility
that the
power brake unit has some malfunction. Verify that there are no
malfunctions and perform part replacement if necessary.
Pedal-to-floor Clearance Inspection
1. Start the engine and depress the brake pedal with a force of 147 N {15.0
kgf, 33.0
lbf}.
2. Measure the distance between the floor panel and the pedal pad center and
verify that the

BRAKE PEDAL REMOVAL/INSTALLATION
CAUTION:
- The clearance between the brake switch and the brake pedal of MTX
vehicles is automatically adjusted to the correct
amount when the brake switch is inserted into the installation hole on the
brake pedal and rotated to fix it in place. If the
brake switch is not properly installed, the clearance may be incorrect,
causing a brake light malfunction. Therefore, always
verify that the brake pedal is properly installed and fully released before
installing the brake switch to the pedal.
- The clearance between the brake switch and the brake pedal of ATX
vehicles is automatically adjusted to the correct amount
when the connector is connected after the brake switch has been properly
installed. If the brake switch is not properly
installed or the connector is connected before installation, the clearance
may be incorrect, causing a brake light
malfunction. Therefore, always verify that the brake switch is properly
installed before connecting the connector.
- Once the brake switch clearance has automatically been adjusted, it
cannot be adjusted again. Therefore, always replace the
brake switch with a new one when replacing the power brake unit or the
pedal, or when performing any procedure that
changes the pedal stroke.
1. Remove the accelerator pedal. (See ACCELERATOR PEDAL
REMOVAL/INSTALLATION).
2. Remove in the order indicated in the table.
3. Install in the reverse order of removal.
CAUTION:
- When replacing the brake pedal component of ATX vehicles, see the
Interlock Cable Installation Note to prevent incorrect
installation could result. (See AUTOMATIC TRANSAXLE SHIFT MECHANISM
REMOVAL/INSTALLATION).
