The procedure is to ensure that the brake master cylinder reservoir is full to the maximum-fill level, loosen and separate the front brake pipe, allow a small amount of brake fluid to gravity bleed, reconnect the brake pipe to the master cylinder port, depress the brake pedal fully and maintain steady pressure on the pedal, loosen the same brake pipe to purge air, tighten the brake pipe, release the brake pedal, loosen and separate the rear brake pipe, and ensure that both of the brake pipe-to-master cylinder fittings are properly tightened after completing the final master cylinder port bleeding procedure.
