Removal and installation the brake pedal (Mazda CX-5KE)

Note: replace the part with a new one after each removal.

Attention.

• The gap between the brake switch and the brake pedal is automatically adjusted to the required value after inserting the switch into the installation hole on the brake pedal bracket and turning it to lock it. If the brake switch is not installed correctly, the gap may not be as specified, causing the brake lights to malfunction. Therefore, before installing the brake switch, be sure to check that the brake pedal is installed correctly and fully released.
• Since the brake switch gap is automatically adjusted, re-adjustment is not required. In addition, when replacing the brake booster or pedal, or after performing any procedure that changes the brake pedal travel, the brake switch must be replaced with a new one.

1. Remove the battery from the shelf.

2. Disconnect the brake lines from the master cylinder.

3. Versions with manual transmission: Disconnect the reserve clutch hydraulic hose from the brake master cylinder.

4. Remove the side trim from the driver's side.

12. Installation is carried out in the reverse order of removal, taking into account the following:

• Check the brake pedal.
• With the pedal fully released, insert the new brake switch into the mounting hole in the pedal cluster bracket.

13. After installation, add brake fluid to the reservoir, remove air from the brake system and check the brake fluid level in the reservoir again.
