Master Cylinder question.
I have never seen any chechballs in those ports, and
call me crazy but if I had a M/C with a checkball in there, I would remove it.
Here is a cutaway of a M/C; the firewall is to the right.
Each reservoir has two ports. One port in each reservoir is for to compensate for wear in the friction materials, and the other;
in the case of the rear reservoir, allows fluid into the chamber between the pistons. This inter-piston chamber, after all the ports are closed to it, becomes a hydraulic connection between the two pistons. In normal operation, there is no mechanical connection between the two pistons unless there is a catastrophic loss of pressure on one side of the dual-brake system; which, if it happens, allows the rear piston to slide into the back of the front piston, and thus half the brake system should still function.
I see no point in having a check-ball in any of those ports, that allowed one-way-only fluid travel; and there is only one port that could receive it and the contraption still continue to function properly.
