Default Re: The New, Newer Project Part Tres...

Since we are looking to get the car judged in the Vintage Certification next year I figured it was time to put the original brake parts back on.

When I got the car, the master cylinder was leaking internally and I sent it off to Whitepost Restorations to be sleeved and rebuilt. They offer a "survivor" service where they don't touch the external finish if you alert them beforehand. They did a wonderful job on the master cylinder which then led to me find out that the two rear wheel cylinders were leaking/stuck in the expanded position. Not a good thing if you want working brakes.

Just as a quick fix to get the braking system fully operable last year, I bought some new brake cylinders and swapped out all the shoes, springs, and the offending cylinders with the idea that they were only going to be temporary while I cleaned the original parts and sent the original cylinders to Whitepost. After a year or so...I finally sent the cylinders off just last week. Within two days I had them back all pretty and nice. They do really nice work with a quick turnaround.

One interesting thing I noticed is that they are the same part number but slightly different castings since one has the "7/8" straight across and the other has it angled. Also the bleeder screws are slightly different as well.

Here is what they looked like in their leaky state:











And when I got them back:

I took all the original springs and soaked them in some detergent to get the adbestos dust off them and also scrubbed the original brake shoes as well. I then reinstalled everything today and bled the brakes.

One interesting thing to note about the assembly line installed shoes is how the bonded front shoe is grooved with a 1/2" slot down the center of the lining. The steel portion of the shoe appears to have a green zinc chromate finish on it. (it is kind of hard to tell from the photo since I used a flash when taking the photos).










And with the drums back on. Each drum had two copper Tinnerman clips holding the drum onto the studs. The passenger side drum also had a "GY" sticker on it.





It also looks like the brake drums are date coded "6 2 73" and "5 30 73".

Today I put the original front brake pads back in. The originals are riveted. The front rotors have a really deep factory depth groove that left a matching peak in the pad. Disc has date code of "G 7 3" (July 7, 1973) FYI: the car was shipped on July 19, 1973.

(BTW, the car doesn't stop nearly as quickly now with the original brake pads and shoes as it did with modern braking materials. [img]<<GRAEMLIN_URL>>/eek.gif[/img])

Driver's side:









Passenger side. Disc has date code of &quot;G 9 3&quot;.

Since it was a record 70 degrees here today, after working on the cars and cleaning the garage, I decided to get a photo of our two
