Hi guys. How full should my master be. Do I fill to the top

Anybody... ?

I don't have that model, but mine specifies the fill level on the cap.

You might have some luck googling the brake actuator. In my case, I found a lot of info on the manufacturer's web site, including instructions on how to fill, bleed, and test the system.

If all else fails, as much as you can put in without spilling any when you put on the cap is a good default.

Most likely someone with your system will chime in, but it might take a day or so.

3/8 to 1/2 inch from top is full. You need some room for expansion with temp changes. Be careful it does not overflow when changing brake pads or shoes. Add some if it gets very much below that 1/2 inch. If you get down much more than 1 inch you might draw some air in to the brake system and may get the opportunity to practice your brake bleeding skills. Not fun.......
