How do you bleed the disc brakes on a magic tilt boat trailer?

To bleed the disc brakes on a Magic Tilt boat trailer, start by ensuring the trailer is level and securely supported. Locate the bleeder valve on each brake caliper, then have an assistant pump the brake pedal several times and hold it down. Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal. Repeat this process until you get a steady stream of clear brake fluid without bubbles, ensuring all air is purged from the system.
