OK I have no brakes on my 1998 Ranger trail with a UFP A 60 brake system. I blead the brakes tonight with a 1 person pump but could not get much fluid to bleed. It was like a trickle at best and took about 100 bleeds to get 80CC of fluid. I had the toung lower that the calipers and kept the master cylinger full. Should I have left the black master cylinder cap off maybe since when I removen it I heard a air excaping sound evert time I removed it to fill the fluid. I tried the brakes and still do not work. Can backup with no brake lockup and not wired to truck and aculaotr slides in 100% in every stop at 5mph. What am I doing wrong as they worked a few months ago.

I will try to see if the master cylinder will hold pressure tomarrow with a screw driver but could it be just the hand pumps cannot bleed this brake system
