    The rear drums seem to be adjusted properly. I can hear and feel the resistance of the shoes contacting the drums when I spin the wheels by hand. I also have a high pedal. I figured that if my drums were out of adjustment that, my peddle would seem low once I apply the brakes.

    Looks like Iím about 98% done with my brake system overhaul and disc brake conversion!

    Last weekend I finished plumbing all the hard and soft lines. This weekend I bench bled and installed the master cylinder and filled and bled the system.

    I still need to extend the wiring to reach the brake switch and replace the vacuum line that runs to the booster from the intake manifold.

    I took the bird for a very short test ride around the neighborhood. She stops, but not with the force that I anticipated. I have a firm peddle and good peddle height; it just feels like I have to push down hard to get her stop promptly. Dave and I think itís probably the old rubber vacuum line with the check valve that Iím temporarily using. The new booster already has a check valve; the vacuum line going to the booster also has a check valve. Itís possible that having the two check valves in line is robbing some vacuum assist.

    Iíll pick up a new piece of vacuum hose tomorrow and eliminate that second check valve. Hopefully thatís the culprit.

    Hereís the bird in her parking spot (facing the other way now )

    Yeah, does the same thing as the one in the fender. I am running that exact tank on our Oldsmobile, for the exact reason you mentioned. It only pulls 7 or 8 pounds of vacuum at idle, not enough to keep the power brakes fed for more than one pedal pump. So far it has solved the problem with the olds brakes.

    You know our 65 tbirds have two vacuum res cans under the hood, which makes sense. It has vacuum door locks, release for the parking brake, lock for the slide away steering wheel, I assume mode doors on the heater, in addition the brakes. I haven't traced it out, but I think Ford separated the systems, hence the two cans.

    Unfortunately, I didn't take close up pictures of the wear pads specifically, but here's a picture of the backing plate after I brushed off all the loose brake dust.

    Looks good ...

    You probably have, but not a bad idea to put a little anti-seize on the adjuster threads. Mike

    Doing a parts inventory check for tomorrow's rear brake job. Once this is done, all that is left is to finish plumbing the brake lines and fill and bleed the system.

    The old reservoir may be filled with brake fluid, too.
    Regardless, I still wouldn't use it because it serves no real purpose and it's just another thing that can go bad. None of my brake systems use a separate reservoir.

    Here's a generic Ford vacuum setup... - Dave

    Thanks Dave - was not familiar with the new boosters having built in reserve but that's great.

    Marcelo - your tank should still be there in the drivers side inner fender (that other hose). Mine still works fine and like Ray mentioned - I'd just use it (until all the use runs out of it )

    Wish I had a pic of the thing showing where it is installed but all I can find is the one of it out by itself. Maybe someone has a parts book that shows it or a pic of theirs still installed.
