I actually drove the E3 on the road the other day, for two blocks, since I didn't want to stray too far from home. The engine still needs attention to get it running smoother but the brakes are the bigger issue now. New master cylinder, front lines were all off the car for paint and the rear lines were cleaned out nicely with brake cleaner. Proportioning valve taken apart and cleaned although wasn't very bad to begin with.
I start bleeding the brakes and I'm having a hell of a time getting the air out. At first I could only get fluid to the first set of lines going to the front, then I tried a pressure bleeder to push the fluid. I got it to come out of the front lines on the master so I tightened them up, then got fluid out of all the wheel cylinders. The pedal goes down to about an inch from the floor. You can pump them up after about five pumps so I know it's just air in the lines, but I can't get anymore out. I bought a Harbor Freight brake bleeder that uses compressed air to create a vacuum and you connect at the caliper and suck the fluid out. I like it and it works great, but all I got our was fluid. I pulled out a lot of fluid but no air.
Ideas?
BTW, the valve on the brake booster seems fine since it doesn't affect the engine running with it connected to the vacuum port or plugged.
