I just completed a front axle rebuild on my 1985 FJ60. I replaced the front brake lines, calipers and pads. I bled the entire system starting at the drums in the rear and then the front. The problem is that while driving, when I depress the pedal slowly I don’t have much brake pressure until the pedal is almost at the floor. When I slam on the brakes I get pressure much earlier (about halfway down and feels more normal). Do I have a booster issue? Master cylinder? Need to re-bleed? Any ideas are appreciated. Thanks!
