I have a 90 civic dx hatchback.

Only the right front caliper, and the left back drum are grabbing.
I have bleed them all, and worked on them, it seems that the left front caliper and pad are only grabbing at the top of the pad,....any idea why, i have pulled both of the calipers off and they both have all the same parts in them, and none are missing. I have even replaced the front left caliper and pads and still only grabbing about 1/4 of the way, also the brake pedal goes almost all the way to the floor, i have full fluids and no air in the lines, please comment.

Thanks.
