Ive been having lots of trouble trying to get decent pressure to the rears... when I bleed them it barely dribbles out. I replaced the MC, which didnt help, and based on responses of people that have had the same problem as me, the problem lies within the proportioning valve. I took it out, and Im thinking of just bypassing it altogeher with some new lines that go straight from the master to the brakes. Has anyone done this? What does everyone think?
