[OVERULD]

I'm in the club too. I like this one from my 2015 Corvette on the assembly line!

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".

Steve, definitely cool to see such an original car. It has been a while since I've looked at any of my brake pads, but do remember seeing a groove like that on the pads and on the front rotors.

I'll add to some info on original details on the drums. In addition to the tinnerman washers and paper decal on the passenger side, the drums were also partially sprayed black, generally just in the area where they could be seen through the Rally II's, presumably to prevent oxidation showing through while on the showroom floor.

Steve, on yours it looks like they sprayed the entire drum including the axle.
