Removing and installing the brake pedal Mazda 3

: Also available:

The gap between the brake light switch and the brake pedal is adjusted automatically when the brake light switch is inserted into the hole on the brake pedal and rotated to lock in place

If the brake light switch is not set properly, the clearance may be incorrect, causing the brake lights to not work properly.

Therefore, before mounting the brake light switch on the pedal, always check the correct installation and position of the brake pedal (fully released).

Once the brake light switch gap has been automatically adjusted, it cannot be adjusted again.

Therefore, replace the switch with a new one when replacing the brake booster or pedal, or when doing any work that changes pedal travel.

Remove the battery and battery tray.
