Brake Hoses, Lines/piping, And Fittings problems of the 2012 Ford Explorer

Multiple times my brakes have had to have repairs because of a failure in the emergency brake system. Twice within the past 6 months I have had the e-brake lock up, get stuck, or fail in a way that required full replacement of my rotors, pads, brake lines, and fluid resulting in thousands of dollars in damages. After the first failure in this, I stopped using the e-brake, however had the problem repeat itself only a few months later. The time earlier this year was noticed when the brakes were pulsating while driving, and the second occurrence this year was noticed when the fluid was drained and a "low brake fluid" light came on, and was further examined after fluid did not stay in the system for very long (matter of an hour or two).
