@RichardJ I have a bad master cylinder so if I have to do anything it's replace the master cylinder, lol.
Also, the stock master cylinder is not the proper one to run for four wheel disc brakes, it can get you by, as mine has, but the rear reservoir is too small. I was just having issues finding an inexpensive one, those Wilwood are too expensive for my little budget. This article spells it out nicely:
