I can’t tell you how much oil, but someone else here probably will. The filter is located mid-tractor on the right hand side (when looking forward from behind the tractor) behind a oblong hexagon cover with six 3/8" bolts.

As far as the brakes, there is an adjustment on each brake. On the right brake, it is a ball/nut looking affair that is located on the brake pedal arm just above the pivot shaft. Once located, you can try to tighten it (turn clockwise) and this will remove free travel from the brake pedal. On the left one there is a short stub on the left side by the clutch pedal that works the same way as the right one.

The brakes consist of two fiber disks that are spleen fit to the bull pinion shaft. The inside one goes between the actuator (more on this later) and the rear end case. The outside one goes between the actuator and the outside brake casting (the part that the adjuster goes into and can be unbolted from the rear end. The actuator consists of two plates that have tapered grooves where balls roll in. As the brake pedal is moved, the two plates rotate in such a way that the balls move in the tapered groves, forcing the plates apart and putting pressure on each of the fiber discs.

Things that can happen to the brakes are: those tapered groves and/or balls get brake residue, rust and other muck (possibly oil from the trans if the seal on the bull pinion shaft is leaking) on them causing the action to get “jumpy” causing grabby brakes, if it’s bad enough, maybe even no brakes. The fiber disks can get worn too thin, and then you run out of adjustment and no brakes. I have even seen it where the actuator disks, transmission housing, and brake cover all wear a little bit adding up to enough that even with new disks you won’t have brakes for long. To cure this I have had the outside brake cover cut down by a machine shop similar to how an engine flywheel is resurfaced. This corrected a lot of my problems, but you need to figure out how much to cut off (if you have a dial indicator, use it to measure the wear on all the pieces and add it up and take that off the brake housing. Don’t get carried away, you can always take off more later if you don’t get enough the first time.

The brakes are not that complicated but can be a pain in the butt to put back together, I usually knock out the plug in the middle of the outside housing (looks kind of like a front wheel bearing cap) to help me see when things get lined up on the bull pinion shaft correctly.

Good luck, post if you have more questions…
