Brakes slowly stop holding while at a stop for too long; such as at a red light or waiting for a train, and takes more force from driver to stop vehicle. After inspecting the braking system I found brake fluid leaking between the brake booster and master cylinder. With a little investigating I found Ford already recalled the same part number for other F150 trucks but mine was not in that group from the same model year. The current recall needs to be expanded to cover every truck with that part number. Due to this failure i was involved in a low speed TC in a parking lot when my brakes stopped holding.
