This procedure is essential when replacing rear brake pads on models such as the Mazda CX-9, Mazda 3, Mazda CX-5, and Mazda CX-6. Following these steps will ensure that you can safely and effectively perform the brake maintenance on your vehicle.

Step 1: Prepare Your Vehicle

• Gather Necessary Tools

  • A reliable OBD-II scanner (with service mode functionality).
  • A torque wrench.
  • Basic hand tools (screwdrivers, wrenches).

• Ensure Safety

  • Park your vehicle on a level surface.
  • Engage the parking brake and turn off the ignition.
  • Disconnect the negative battery terminal to avoid electrical issues.

Step 2: Connect the OBD-II Scanner

• Locate the OBD-II Port

  • The port is usually located under the dashboard, near the driver's seat.

• Plug in the Scanner

  • Insert the OBD-II scanner into the port.

• Turn on the Ignition

  • Switch the ignition to the "On" position without starting the engine. This will power the scanner.

Step 3: Enter Maintenance Mode

• Select the Appropriate Mode

  • Choose the "Maintenance Mode" or "Calibrate" option.
  • Follow the on-screen prompts to activate maintenance mode.

  • Ensure the scanner indicates that the vehicle is now in maintenance mode. This may involve a confirmation step on the scanner.

Step 4: Replace Rear Brake Pads

  • Use a jack to lift the vehicle and secure it with jack stands.
  • Remove the wheel lug nuts and take off the wheel.

• Remove the Brake Caliper

  • Unbolt the caliper and gently slide it off the brake rotor.
  • Hang the caliper using a bungee cord or wire to avoid stressing the brake line.

• Replace the Brake Pads

  • Remove the old brake pads and replace them with new ones.
  • Ensure they are properly seated in the caliper bracket.

• Reinstall the Brake Caliper

  • Carefully reposition the caliper over the new brake pads.
  • Bolt the caliper back into place and ensure it is secure.

Step 5: Exit Maintenance Mode

• Return to the OBD-II Scanner

  • With the brake replacement complete, return to the OBD-II scanner.

• Select Exit Maintenance Mode

  • Navigate back to the service menu and choose the option to exit maintenance mode.

• Disconnect the Scanner

  • Once confirmed, unplug the OBD-II scanner from the port.

Step 6: Reconnect the Battery and Test

• Reconnect the Negative Battery Terminal

  • Ensure the connection is secure.

• Test the Brakes

  • Start the vehicle and test the brakes by gently pressing the pedal.
  • Check for any warning lights on the dashboard.

Conclusion

By following these steps, you can successfully put your Mazda into maintenance mode and replace the rear brake pads.
