I'm finishing up rebuilding my brake booster and I need to bleed the system. I don't think I bench bled enough so my brakes are still squishy. I'm pretty sure the circuit coming out of the top of the master cylinder is well bled. The bottom circuit, however, is suspect. I have the diagram for the 850 master cylinder which has ports on the side, but not the 840 which has ports on the top and bottom. Which circuit comes off the bottom of the master cylinder, front or rear? Thanks!
