I have what I believe is a 1969 644A Wheel loader that has been a great machine. We are getting it ready for snow season, but towards the end of last year's snow season the brake pedal got very stiff and required way more force than usual to make the machine stop quickly. The feeling is very similar to an old 7.3 IDI f350's brakes when the vacuum pump failed or an old international with a hydroboost system when the power steering pump failed. Is there something that provides braking assistance in these deeres? This is not an air or air assist system either. Any thoughts or insight would be great!
