brake problems... need help!
#17
I had the same problem with my Bronco 2. It only takes a TINY amout of air to make the whole thing soft. AND you would be surprised at how important the back brakes are. Use the 2-person bleed method and buy a large container of brake fluid.
I ended up disabling the rear ABS because I HATE ABS and it was causnig the response in the rear to be sluggish. To disable, remove the fuse and ignore the light.

I don't think it will. IIRC, the Bronco II had a RABS on it, not 4 wheel ABS. Different animal entirely. Unfortunately, to properly bleed a 4 wheel ABS with air in the HCU (Hydraulic Control Unit) there is a special tool that will cycle all the valves and the pump in the control unit to force all the air out.
I really don't know what to suggest at this point. Being as brakes are such an important piece of safety equipment it's difficult to diagnose remotely. If it was me, I'd take it to someone to have it bled with the tool and see if that helps.
I'm also wondering if something in the HCU could have malfunctioned. The RABS system has a dump valve that releases pressure on the rear brakes. If it sticks open or leaks, brake pressure would bleed off and it seems the brakes would feel soft. Maybe something similar has happened here, but I don't know how I'd test for it.
