On our rangers, do our hoses make an X?? OR is it traditional front/rear set up?? ABS?
I ask this....becuase this might be the reason for your problem.....If the brake hoses on our trucks make an X, you gotta bleed the entire system. But I an completely unsure as i've never actually looked. lol.
well my buddy had the same issue on his gran prix. We tried it for days, then i looked it up online and found out there was a certain order of which brakes to do.
You might have to do something like that.
But since you were only in the front, i can't imagine the rear brakes affecting it.
