| Description of the problem | On july 18, 2019 vehicle (2016 ford f150 with 51,721 miles) driven under highway conditions experience a 'low brake fluid' warning followed afterwards with complete loss of brakes when attempting to secure the vehicle to a safe condition. Fortunately the driving situation allowed the vehicle to be secured safely. Upon inspecting the vehicle there were no indication of brake fluid loss through broken brake lines or system leakage. Subsequently transported the vehicle to the vehicle our originating ford dealership, the shop diagnostic result was the 'failure of the master brake cylinder rear cup seal'. Additional damage included the booster pump due to brake fluid contamination. Issues: this is the same failure to which ford motor previously recalled 2013 - 2014 f150's. At 51k miles, the failure of a master cylinder is premature. During routine maintenance, inspection of the master cylinder does not readily lead to indication of potential failure or need for replacement. This failure could be catastrophic under the right conditions if proper operator control is not followed - lower speed by reducing gearing and using the emergency brakes. The replacements are oem factory parts; possibly the same manufacture as that replaced which could be potential for future failure (this could not be clarified by the ford shop at the time of the work)! The primary concern of course potential for relapse of the same event. Secondarily is the premature expense of master brake cylinder and booster pump replacement. |
