I've had a newer aftermarket power brake booster and master cylinder in my 64 Coupe DeVille the past few years and it has very few miles (and on the way to good home now), and has been a great brake setup, but as I continue to restore my car to an "Original Look" this was one of the areas I wanted to return to original in appearance. It is also one of the areas I would get dinged a point or two when I take the car to the Grand National for Judging, and I just like the original setup better anyway! I've had an original rebuilt Delco Morraine waiting to go in my 64 for well over a year and finally got around to installing it this week.
According to the shop manual the Delco Morraine is zinc plated. It doesn't list it as yellow zinc or silver zinc. My booster and master cylinder came silver-grey which is the natural color of zinc anyway so I think I'm in the ballpark! Also looking at Fig 6-10 in the shop manual the cap looks a little lighter and the hold down clamp is black. The cover was scruffed up a bit anyway and painted it with the Tank Tone paint I bought from Eastwood sometime back, and painted the hold down clamp black. I put a washer beneath it to protect the paint until it cures more.
I have a car show this weekend and was a bit nervous about removing and replacing the brakes booster and master cylinder, but all is installed, brake system has been bled and all is working perfectly! I used a vacuum pump to bleed the brakes which was a first for me, and now I'm asking myself why I didn't use this method 30 years ago!
Below are pictures of the aftermarket setup I have had in the car, the rebuilt original Delco Morraine setup I've had waiting in the wings for over a year to installed, and everything installed in the car and ready for this weekend's meet-up and car show with the NC Eastern CLC Members in Clayton, NC.
