Jason Coupe DeVille Resto - Rebuilt Original Power Brake Booster and Master Cylinder Installed

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.

Tony, your description is the 2- person brake bleeding I think most of us are familiar. The vacuum pump and cup allows for one person brake bleeding. It's probably been 10 years since I had to run in the house and grab Cheryl to help me bleed brakes! LOL

You can bleed brakes easily without the vacuum tool expense
Open the zerk on the wheel cylinder and have a second person push the brake peddle to the floor
Fluid will be squirting out ( can use a tube and collection bottle or just have it hit the floor )
Hold the peddle there while closing the zerk
Repeat until you get only brake fluid coming out of the the zerk
Do not let the level of brake fluid get to low in the Master cylinder

The brake peddle should feel super hard and have about a 1/4 inch or so of travel when right on these cars
No soft peddle like the ABS type brake feel

Adjusting brakes this way for about 50 years

The correct brake tool to open and close the zerk is important as they are soft brass fittings and can strip easily
The correct tool can help getting into a sometimes tight spot with some zerk locations

Enjoy

Thanks, this is a great idea and will try it when I replace all suspension, coils, steering parts from Kanter this spring.

You can get vacuum pump & brake bleed kits here in the US. I use this one available at Auto Zone for $35: http://www.autozone.com/test-scan-and-specialty-tools/vacuum-pump-b...

You are basically just pulling the fluid into a cup until it pulls just fluid and no air. Attached one end of hose to brake bleeder, the other to the pump, the other hose to the cup, loosen the bleeder and pump until fluid runs into the cup, tighten the bleeder. Here is a picture of the kit. I actually have 2, which is useful for testing check valves since  you need to make sure 2 nipples are holding vacuum. See my Check Valve Testing video on Help page for a visual.

Jason, you mention using a vacuum pump when bleeding. Would really like to see the setup on that. I think I have an idea how its done, but an explanation and maybe some pictures of the equipment used would be much appreciated.

In 2013 when this was posted, Autozone was selling original rebuilt booster & master cylinders rebuilt for about $150 as I recall.  Their stock run dry about 2 years ago and while I have seen the master cylinder and booster listed on their parts page, they are still out of stock the last time I checked. Cardone in TX can rebuild your original. They are listed on our Parts Suppliers page.

Where did you find your rebuild kit for the booster? I see several onine and looks like they are expensive.

A lot of discussion on brakes the last couple days and thought I would bump this back up.
