Need Help with '66 Brakes

[spyacoach]

Not sure if this is the right place, but I thought it might get seen here.

We recently replaced both front and rear brakes, wheel cylinders, calipers and rotors on a '66 T-Bird. This car has a single-stage Master Cylinder and no proportioning valve that we have found.

We're completely unable to get ANY fluid through the front calipers, as in to bleed them and there is absolutely no pedal. When we bled the rears, we were able to get clean fluid through the bleeder valve, but it didn't seem like a very strong flow. We thought maybe the Master Cylinder, so we bought a new one, which specifically instructed NOT to bench bleed it, so we didn't. We bought the vacuum pump/bleeder device which doesn't seem to have much suction, but we THINK we've done everything right. We still get nothing through the front calipers, although there is not a blocked line, as when we disconnect them, there is a normal "Gravity Drip".

Can anyone offer up any suggestions? Have we missed something?

Suggest you "repost" this in the "Flair Bird" 1964-1966 section. You probably will get better response. By the way......I converted my 66 to a dual chamber master cylinder. I have photo's and parts list if you are interested.

The valve is right below the master cylinder just above the steering box. The brake lines go to it. I use a power bleeder on my cars. There are other methods people use.

Had the same issue on one of the 3 65's I had here, replaced frt hoses, and m/c and couldnt get any brakes up front after. I ended up letting them gravity bleed over night and it finally worked.

I did a silly thing once on one of my '65. After putting on new calipers and bleeding for what seemed like hours I had -0- pedal, even reverted to manual bleeding thinking my power bleeder was faulty. What I discovered was I had the calipers on the wrong side. The Calipers will physically bolt either left or right... The bleed screw was facing upwards, which would never ever bleed properly. Swapped sides and as soon as I started bleeding the pedal got firm. Hope it is that easy for you.
