I just finished rebuilding the manual drum brakes on my 67FB. I replaced everything, other than the lines and MC. While having the lines disconnected, the MC leaked all the fluid out. I put everything back together, and proceeded to bleed the lines. All bled ok. I then cranked up the car, and the brake light is now on, where it wasn't before. I didn't mess with the connector on the top of the firewall block where the lines connect to, but once I noticed the problem, I reseated it anyway. No help. So what could be the issue? The brakes seem to work fine, although they are slightly mushy. I'm not sure if I just didn't bleed them good enough, or if I should go ahead and replace the MC, since I rebuilt everything else.
Any opinions?
