Brake fluid just disappears when tractor is setting,no visible leaks anywhere clutch and brake mastercylinders dry, clutch slave cylinder dry traced all hoses and steel lines and are all dry the only two things left are the left and right brake cylinders under the seat and they are not visibly wet, is it possible for them to leak internally into the differential? Forgot to mention I lose brakes totally left and right side. Help

Hi

The supers have 2 different brake wheel cylinder setups. The later ones (probably around 2003) have an external cylinder. The early ones have the cylinder built into a housing fitted to the top of the axle with 3 allen screws. This early type can leak internally. They aren't nice to get at and the only way to tell if they're leaking is to remove them. When you've got them out, if the bottom dirt seal is pushed off, they are leaking. They're normally rusty. Polish them up with emery paper before you re-seal them because they are VERY expensive to replace.
Just a thought, has yours got front wheel brakes ?
