Thanks. When you say on the frame, is that on the inside or the outside, and by frame, I am guessing the big slab side 1/2 plate on each side?

How much total hydraulic oil in the whole system?

I think the master cylinder on the left that I checked is the only one, it connected by link to the brake pedal, the only one I saw during brief check out.

Can't get to the other side of machine, parked against stuff now, will check out when get time.
