Default '60 Tbird Power Brake Spacer Kit

Does anyone happen to have this NOS, unused kit in their back pocket?

C0SZ-2A251-A 1960Tbird Power Brake Spacer Kit

This is the kit that is needed if you are adding AC to a '60 Tbird. The kit allows you to get the then single power booster with the single MC attached to it, past the AC plenum box. It is something that Ford found they were going to have to add to accomplish this. I assume that it was a kit Ford put out to their dealers for those we were adding AC to their '60 Squarebird and would have the problem of getting that round power booster away from the AC plenum box. They are very rare, and I am told that many people have never seen one. Below are some pix of what it looks like and how to install it.

The reason I am asking is that I am trying to locate one of these units, complete, in the box, not in use, with all the parts. I want to see about having it replicated on a CAD machine so that someone can put it back into production and offer it for sale. This kit should fulfill the need for those who already have AC on their Squarebird, but want to make the conversion from single MC/booster to 2 stage MC/Booster. We have been having nothing but problems in finding a mounting bracket that will clear that AC plenum box. This should do the trick if we can find one and replicate it. If I can't find one here, I am gonna start canvassing the OEM/Old/Rare Parts companies by that Ford Part # to see if I can come up with one.

If you have one, please call, email or PM me... Thanks!

What a great idea to clone a factory bracket. This bracket seems to always come up when doing a disc conversion.
You work on the brake bracket and I'm still working on getting the brass window rollers fabbed. Think I am getting close.

Sorry, but it won't fit a modern booster.
In a perfect world where the firewall bracket and booster were made for each other, it would work with the addition of the REST OF THE KIT (longer hockey stick/brake pedal rod).

New boosters use a different height and width to their hole pattern, as you can see:



Remember, the original booster was riveted to the firewall bracket so they could not be separated. That forced the 'extension' to go between the bracket and firewall. We have two better solutions. Either cut the rivets off your booster (because it doesn't offer enough boost for disk brakes) and add your own extension* for the new booster OR fabricate your own firewall bracket using Howard's plans.
* This way you retain your original hardware from the pedal to the firewall bracket.

I sincerely hope the old Ford kit doesn't come up again and I hope nobody buys one. Ford's original power drum brake system was terrible at best. Disk brakes require far more boost. If you want to have something made, send out Howard's plans for a new firewall bracket. - Dave

Default '60 Tbird Power Brake Spacer Kit

Thanks, Dave, I guess I should have run that through you first before I posted it. I did not know that it would not work with our modern dual stage boosters. I made the assumption that it would. Oh well! The interesting thing is that one of our own members happens to own one... or used to....

Default Booster bracket

As Dave says the dealer installed bracket alone will not solve the problem. It was designed to be used with the factory firewall mounted booster and bracket. It fit the firewall bolt pattern and consequently the booster bracket. It fit between the firewall and the booster bracket and came with a longer hockey stick. To utilize it you would have to take an orIginla booster and remove the bracket as we have done to mount the new booster on non a/c cars.

Original Tbird 8 inch single stage booster - approx 650 psi boost pressure with 23 inches of vac.

New dual stage 8 inch booster approx 900 psi boost pressure with 23 inches of vac.

Only about 250 psi increase.

The originals work fine - very fine - and has been working fine for 10+ years

(with the booster face replaced to accept a modern master cyl - thanks Booster Dewy)





Even on those steep mountain roads


and there it is 10 years later still working fine - even outlasted the engine


As Grant mentions - you could always cut the Tbird single stage booster off and use the original bracket with the spacer if you wanted a newer booster. The kit would have the needed longer brake pedal rod. The biggest advantage I see is it that the newer boosters would be cheaper and quicker to replace (until someone comes up with a new brake idea and they quit making boosters ).

Still a worthwhile project IMHO even if only to give the current bracket makers some competition and reduce prices.

Default Booster bracket

The simplest way to solve the A/C clearance problem is to cut the original bracket off the old under hood booster and add an extension. That way you don't have to change anything from the brake pedal to the booster. MBM sells a 74-95 Jeep extension bracket that will work. Part Number B7495. It has elongated holes that will fit the Ford original bracket according to their website. If you have the under dash booster you need to come up with an under the hood type booster to get the bracket.

Hope this helps, Gary

How would you like a CHROME 8" Two stage universal booster for UNDER $55 (with free shipping)?

CLICK HERE

The input bolt centers are on standard 3-3/8" square and it comes with a check valve.

As for the Ford extension... If you already have a OEM booster with all the necessary hardware connected to your brake pedal, why would you disturb that by replacing it with the same thing?

To retrofit a modern booster, simply cut the rivets off your OEM booster and keep the firewall bracket on the firewall, just as it always was. Then connect a new universal booster to that using your own spacer. Yes, you need to drill four holes in your spacer but you can widen and use the rivet holes in the firewall bracket side and put the booster holes on 3-3/8" (standard) centers.

As Eric said, the new two-stage 8" boosters produce about 40% more than drum brake OEM boosters. Disk brake calipers need at least that much to work properly.

The bellows-type boosters offer very little-to-nothing for power brakes. - Dave

Dave - some nut would want to do that if they were putting A/C on a car that did not originally have A/C.......oh wait......that describes me exactly......on both accounts.

Eric

(I've always wondered how much pressure the old bellows booster under the dash produces (just for grins)).

Eric, Howard Prout's convertible came with no air so he added factory air (and his 8" two-stage booster).

You should cash-in on this Amazon deal, Eric. I almost want to go down to NC, re-mount your upper ball joints and add this booster. If you lived closer I would because I have a lot of respect for you and how you 'pioneered' power disk brakes for the rest of us. Besides that, you are a great guy. - Dave
