BRAKE PEDAL REMOVAL/INSTALLATION

Caution:

The clearance between the brake switch and the brake pedal 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 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.
Once the brake switch clearance has automatically been adjusted, it cannot be adjusted again. Therefore, replace the switch with a new one when replacing the power brake unit or the pedal, or performing any procedure that changes the pedal stroke.
Remove the battery and battery tray.
Disconnect the brake pipe (master cylinder side).
Remove the accelerator pedal.
Remove in the order indicated in the table.
Install in the reverse order of removal.
