So, I changed the right front caliper & both front pads & now I only have front brakes! I pulled the hard line loose where it goes into the rubber lines & it was nothing coming out, barely wet. What could be causing this. Oh, it's a 93 Ranger XLT 2WD, sorry.

 

I'd suspect that the master cylinder is bad. Crack the connections coming out of the master cylinder and slowly pump the brakes to see if any fluid comes out.

 

I did. both lines & fluid came out. What about the ABS equalizer block down on the drivers side of the frame.

 

That's another possibility and they can be notoriously difficult to bleed through - they're also expensive. I'm not familiar with the ABS on a Ranger but I had a heck of time bleeding my 1990 Mazda Miata. I ended up taking it in to a shop and they power bled it for me.
