If Matcos are like Clevelands, that allen screw is just an air vent or a possible place to top it off with a syringe if necessary. Here's how I do the Clevelands. The object is work from the bottom up so the air bubbles rise with the fluid, rather than against it. Remove that screw so there's a way for the air to enter and exit the cylinder. Buy a new oil can with the lever on the side and fill it with brake fluid. Use a piece of polyurethane tubing that fits both the end of the oil can and more importantly the brake bleeder valve. Pump brake fluid until there's nothing but fluid in the tube, then connect to the bleeder valve. Open the bleeder valve and pump away. It takes a good many pumps to fill the line and cylinder, but grand total for mine (when empty) is about 60 strokes. you shouldn't need nearly that many to just bleed it. I use a thin white tie wrap about 4" long as a dip stick, and check through the screw hole that the allen screw came out of . When it's about 2/3 full, I quit pumping, shut the bleed valve, and go do the other side. I'm no Matco expert, but I'd think there would be some kind of relief screw or equalization hole or something on top of that cylinder. You might want to wrap the cylinder with a paper towel in case you over fill it. I've done that a time or two, so now I do exactly that. Come to think of it, you may know everything I just said, except what the deal is with that screw. If so, my apologies, because I don't know the answer to that one either.
