2. Connect electrical wiring – attach magnet leads to your trailer's brake wiring (ground or positive configuration).

3. Break-in procedure – After installation, perform a burnishing cycle: make 20-30 gradual brake applications while driving to properly seat the new friction shoes.

4. Periodic inspection – Check every 6 months to ensure the self-adjuster mechanism is functioning properly.
