1957 Master Cylinder Question

Hi there,
Is there any way to:

1.) Convert to a newer dual resivoir master?

2.) Convert and move the master to the upper firewall? I know the fresh air vents are there, but there is a lot of solid firewall in between them that could be beefed up with some 1/4" plate stock.


Thanks

You shouldn't have any problem converting to a more modern dual chamber master cylinder. Oldsguy converted the brakes on his 69 Delta 88 from power assist to manual. I would think the only thing you would have to do is make sure the movement of the plunger in your master cylinder allowed full actuation of the slave cylinders. Moving the master cylinder would be a bit more difficult. You would actually have to change the geometry in how the brake pedal moves the plunger in the master cylinder. If you are good with engineering this would be easier.

PM Oldsguy or keep this near the top, he can at least let you know what it was like modifying the brakes on his Delta. Also, someone else might have already done what you are looking to do. Good luck!

mbat, I know what you are attempting to do. It is a little different than what I did since the MC was already mounted high and I could use the same hanger mechanism. I have heard of people changing to an upper mounted dual MC in the older cars. You might get some responses from people who have actually done this over at the Jalopyjournal.com website, then navigate to the H.A.M.B. sub forum. Lots of older cars there and it is free to join.

I would love to see someone start converting these old power brake boosters to dual reseviors. I honestly feel these are good units and have them on my (semi - daily driven ) '57 and '59 Oldsmobiles. I know that on the firewall on my '59, there are holes covered up with rubber grommets. I didnt think much of it until I figured out these were punched out holes for cars equipped with Manual brakes. I may just need a manual brake pedal assembly and a new dual master. I may start this conversion next Spring.
