I have done alot of thinking on my car and have decided to sell it and my other toy (91 Camaro vert) and buy what I want, a 55. I think my car will be worth more if I spend the money and time to get the brakes going again. The master leaks bad and the lines need replaced. I figure it would be about the same to put an original master in verses a dual master without a booster, which would be more appealing. Who makes the cheapest conversion to do this? I'm sure many have done a lot of research and I would like your input. I need to build what I want now while I have a few extra bucks and too many cars.

Look at Chassis Engineering AS-1049BC and AS-1054BC. These give you just the mounting bracket for $110 and you have to buy a MC separately. The Filling Station BB-440 uses your original MC as the mount for the dual MC. This one is $230, but it also includes the dual MC.

I think the CE setup will cost less overall because you could get the dual MC at an outfit like Rockauto and save quite a bit of money compared with buying it from the specialty parts vendor.

Also check out Engineered Components. They use a Mustang MC with a bracket that mounts to the stock one. You'll have to enlarge the hole in your floor.

I just completed this install. It was a lot of parts sourcing and running around town and purchasing online as well. I used the Chassis Engineering bracket. I can weld but am not confident enough to build my own bracket. I bought a new MC for manual drum brake 68 mustang application from cjponyparts. I replaced all hard lines with a stock prebent setup from ecklers, then used NICO lines from a local auto supply to connect to the new master. I also sourced the fittings to adapt the stock sized lines to the MC from a local fitting supply shop. For the brake rod, I used a 3/8 grade 8 bolt on a heim rod using an adjustable nut. I used 10 psi residual valves from Wilwood. The car stops very well. If you're good with a flaring tool (I am not) you could just bend and flare all your own lines and save $140.


Chassis Engineering bracket: $110
Prebent brake lines: $140
Heim rod/ bolt: $25
MC adapters for brake line: $4
Brand new dual master (not refurb): $50
New Flex lines (3): $60
"T" fitting for front: $3
Residual valves (2): $38
TOTAL: $430

I also replaced the wheel cylinders and installed speed bleeder valves.
So overall I had about $500 in a total brake system rebuild and didn't have to fab any of my own parts.

I'm using a 1969 Corvette MC and booster. They work well together and you can buy them right off the shelf at most any auto parts place.

What pedal assembly did you use?

Using a pedal assembly out of a 2012 Chevy Captiva that I found on Ebay. I did not install it myself but the garage that did install it only took a couple of hours so it couldn't have been that hard...

The guy who runs the shop has a late 30s Plymouth street rod so he knows bit about fabrication. Most garages don't want anything to do with fabrication. They just want to install plug and play parts...

It's not that I won't fabricate parts, I love doing it; but its not very cost effective to the customer.
If it would take 5 + hours to build and fit something, compared to 1 hour to install a prefab; which would be your choice, as a customer? Yes it would depend on the cost of the part; but a company that has build hundreds; compared to a one off, will likely be cheaper.
Me as a garage owner, I would prefer to build and get the extra labour.
The next thing is, once something has been built and installed, it may look very strait forward and simple. The customer usually has a hard time believing it took you all that labour to complete it.
Anyone here who has built bracketing or braces from scratch, will understand that it takes time; usually a lot more then expected.

What Dan is saying is very, very true. Rarely does the customer understand the time it takes to fab and install a part. I contunue to be surprized at how long I spend designing, building and installing a part.

Along these lines, I did find the 67-69 Camaro pedal assembly worked very well in the '53. They reproduce it complete with pedals, rods, and z-bar for around 200 dollars if a used one can not be found. You would need to find a factory hanger but they are similar for automatic or straight shift cars as well as 2nd gen nova.

Hi Scott, if you go underfloor un-boosted then stay with the master bore the factory single was.

Two different sizes in our years.
Also it will bleed easier and stop better with 10 psi RLP valves in each line.

There was one in inside every original single underfloor master. They are always required when the master is below the wheel cylinders or disc calipers to prevent the effect of gravity suctioning in air on pedal release.
