Hi, We have a 2010 Terex TA400, and the hydraulic and brake fluid are mixing, overflowing one reservoir and emptying the other. Also, while rolling, the brakes will engage randomly without touching the pedal. An older post on a TA40 pointed to a bad pump seal for a similar problem, or bad brake cylinders. Would that seem to be the issue here? Is there a way to pinpoint the problem? Thank you for any help.
