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.

To Jason:

Could you share your “newer aftermarket power brake booster and master cylinder in my 64 Coupe DeVille” details?

Comment by Mike Travers on November 9, 2022 at 8:57am

Yes, I found out that it is indeed hard (impossible) to find a good new brake booster for our '63s. I ended up rebuilding my Delco style booster with the new rebuild parts and it works great. Those boosters are relatively easy to rebuild. I even made my own tool to spin the two shells apart on the booster. Anyone in the club needing that tool is welcome to borrow mine. I'd even be willing to share my rebuilding experience, as long as this old brain can remember the procedure.  :-)

There are a bunch of venders that say their booster will fit a 63. I ordered 4 and none fit, had to eat the cost of return shipping each time even after been assured it would fit.

Looks like the only way is to rebuild the one you have. Or buy a rebuilt one

let us know if you find one.

My ‘63 DeVille had the Bendix set up. No repair kit is available so, i too purchased the Cardone  remanufactured 54-71301 and an AC Delco master cylinder: AC 18M1058. The combination bolted up without modifications. We believe the booster has an internal valve failure as determined by the Cardone service tech line. Although it is covered by warranty, no replacements are available. The OhOhOh O’Reilly brand “BrakeBest” is same part number. Is there an alternative booster that will fit this application?

Comment by Eunan on October 5, 2022 at 8:46pm

Finally got my brake booter installed.

Note: THE 64 DEVILLE BRAKE BOOSTER WILL NOT FIT ON A 63 DEVILLE without modifying the car or booster

I ended up over sizing the holes on the firewall and brake pedal bracket and then adding washers.

The large center hole and master cylinder didn't need any modifications  

If I had this information before I bought the 64 booter I would not have done so, hopefully this can helps somebody else out there.

Will do.

Hopefully I get the booster installed in coming weeks...

Comment by Mike Travers on August 8, 2022 at 3:36pm

Eunan - Thanks for the reply. Your information is indeed very helpful. Jason got me fixed up with a rebuildable unit but I may still purchase a new unit from O'Reilly. Please keep me posted once you install yours so I can check on the fit & finish.

Comment by Eunan on August 8, 2022 at 2:04am

Yes,

Mike, yes, I found the Delco brake booster.

I have a 63 Deville but the 64 booter will work,

I have not installed it yet, but it should be good the first one I got was assembled sideways so had to order it again. 

I got it at Oreilly Autoparts you have to be careful ordering it won't come up in their system.

They have to order direct form the vender some of the workers have no idea how to, so you have to find the right person i went to 3 stores before they ordered the booster.

The Part number is 54-71301 

Hope this helps...

Eunan - Did you ever find a 64 Delco booster? I'm in need of a Delco booster for my '63 but it sounds like a 64 Delco would work, as well.

Comment by Eunan on May 30, 2022 at 9:58am

Yes, that's the information I needed. I ordered a 64 booster (Delco) but the measurements at the fire wall were 3 9/16" side to side and 3 3/4" top to bottom. So, I'm guessing jurying assembly the casing got put together wrong

I've ordered another booster hopefully the next one fits 

Thank you for the information very helpful...

I removed the front cover to change out the timing chain & gears all that went pretty well when I put the cover back on I put in a fresh oil filter ,filled it up figured it would be enough to prime the oil pump when I started the car .Fired up the car and heard lifters rattling, So I shut the car down right away. So I removed the oil filter housing, and poured oil down the neck of the oil pump housing filled it up and filled up the filter put it all together and fired it up and same…

Caddy members, I’m upgrading my 64 2-door coupe deville.

motor guy lost my block (machine shop went under) so I’m replacing motor & tranny with LS conversion. I have motor parts (other than block) for 429, rebuilt transmission, converter, and too many other motor parts not needed with fully dressed LS going in.

Email me (Tom.reichenberger@ipsper.com) or call me (210-739-4854) if you’re interested…..I live in San Antonio, TX.

thanks, TX…

Trunk Open and Lock Mechanism is in Closed Position

Posted by Chris Anderson on September 13, 2022 at 7:14pm 7 Comments

While working on my trunk lock on 64 Cadillac, I mistakenly closed the locking mechanism while the trunk was open.  Is there an easy way to manually release the lock back to the open position?

Thanks.

Fuel Pump Failure

Posted by Jon Shields on August 6, 2022 at 6:48am 4 Comments

Hello,

I'm located in Melbourne, Australia and my 64 sedan de ville is stuck in the garage due to failed mechanical fuel pump. The first after market mechanical fuel pump lasted a few years before it failed & left me stranded 5 hours from home. A hire car and tow got us home. On inspection, I noticed a valve not seated within the housing. I was optimistic, pressed it into place and assumed the pump was good to go. But alas, no. From what I can now determine, the diaphragm pushrod…
