1966 Master Cylinder Quiz Which one is the right one?

[Darrellinceres]

Okay so the car has been sitting for seven years and I finally got the time to do it. I've rebuilt the motor (428) had the trany redone, yada yada yada. I'm almost ready to start it. Just a few details.

My problem is that somewhere the original Brake Master Cylinder got lost. The manufacture date is 3/23/66 from the vin numbers. Now I've seen two different types of master cylinders listed for this year and there seems to be a change around January 66. Does anyone know what the difference is and which one is the correct one for my bird.

Well I guess I'm just going to have to take a shot in the dark. Does anyone at least have some photos that show the master cylinder and how it's connected? Does it have a switch mounted to it? I'm purchasing the Raybestose Part Number: MC36252 which looks right from the pictures I've found on-line but it's hard to see beecause it's usually hidden behind the support bracket.

Thanks

Well I got the master cylinder and I still have something missing. The MC has two ports and I have three brake lines. Can someone Please help.

[boaterbob]

Maybe one line goes to the proportioning valve below the m/c.

[boaterbob]

Okay, Just looked at my M/C One line comes out the front and two lines go to the bottom. There is a brass tee on the bottom. Thats what your missing.

Boaterbob,
Thanks for getting back to me. I was beginning to think that there wasn’t anybody with a 66 left in this forum.
What I’m missing is the brass tee. Does the line to the proportioning valve connect to the front of the MC and the two front brake lines go to the tee on the bottom hole? Now all I’ve got to do is find one of those tees. I’ll have to look for someone’s “Parting Out” ad and see if I can find one. I probably can get one from that bone yard in Arizona.
I’m also trying to contact my local Thunderbird club and see if anyone has a 66 that I can look at. I’ve been using Jim Wulf’s T-Bird garage as a source of pictures to see how things were routed. I’m trying to put it back together as original as I can. Would you have any pictures of the engine compartment on your Bird? Something that shows the MC and the fitting?

Boaterbob,
That brass tee. Is it male threadded on one end to fit into the MC, has one FM out the side and one straigh out? Do you have a TBirdHQ catalog? Does it look like the one on page 18 P/N: B2075C

[boaterbob]

Yes that is the tee #b2075c. The line that comes out of the front of the m/c goes to the p/v. If you have a email i can try to send you a pic, But its pretty straight foward as i said

This way I can make sure I route the lines right.

Thank you very much.

Keeping it original is fine. But, if you decide to convert it to a dual master cylinder (for safety reasons) let me know. I have photo's of the conversion process and complete parts list.

Thanks. I've seen that in a few forum posts about people changing to the duel MC.

I have another question about the brakes. In the manual it says never to remove the bolts holding the two halves of the brake calipers together. Is it really that bad of a thing? I was pulling my calipers off for the first time so I could get the rust knocked of the rotors and replace the bearings and removed those by accident. I didn’t actually take them apart. I realized what I had done and put them back and re-tightened them. Anything I should worry about?
