Fill the master cylinder reservoir with fluid, then bleed the master cylinder and the brake system. Have an assistant depress the brake pedal and hold it to the floor. Loosen the fitting to allow air and fluid to escape. Repeat this procedure on both fittings until the fluid is clear of air bubbles. Have plenty of rags on hand to catch the fluid, as brake fluid will ruin painted surfaces. After bleeding, rinse the area under the master cylinder with clean water.
