Brakes: Dual Bowl master cylinder kit from Turner Brakes

[BassMan]

Hello to All---Hope you are well. I probably will start my rebuilt engine this coming week. While I'm holding my breath, I have a quick question. The car had power brakes and front disk from Turner Brakes. I want to put the dual master cylinder on, while the engine is out of the car. I want to go with standard brakes( no power brakes ) and add the dual master cylinder. I believe I have read that you cannot add the dual MC and still have power--Is that correct? If that indeed is thecase , it's OK because I do not want the power brakes anyway.

Do I need a pressure regulator in the front and back brakes both? I know the car had couple of valves of some kind to maintain a certain amount of pressure in the lines all of the time. One was a 2 lb and the other was a 10 lb, but I do not remember while I'm writing this which way they went. I believe the 2 lb was in the front lines and the 10 lb was in the back. Also, there was a pressure regulator going to the rear brakes as well, to prevent too much pressure from being applied to the rears. Do I need this same setup for the dual bowl system as well ? If anyone has any words of wisdom or suggestions before I start on this, I'd love to hear your suggestions. Thanks again -----BassMan ps---Do I need a new " brake pedal" in this change over ?
ps again---this is a 1957 Silver Hawk with a 289 engine

Have you tried asking Jim Turner at Turner Brake what is the best setup, given that you are going without a Power Brake Unit and a Dual master Cyl. ?

I did just what StudeRich suggested when I restored my 60 Lark Convert. Stayed with standard (non Power) brakes. Jim provided all hardware, valves, and installation instructions and a choice of modern master cylinders that are compatible to be used whit the kit in stock position. It truly is a bolt in kit with no fabricobbling required. I did however enlarge the hole in the floor to make checking/filling the master easier. It is tried and tested. No need to look elsewhere. Good kit from a good guy .

Thanks pinehurstbob and StudeRich----Sounds like good suggestions to me ! I will call Jim Turner.

The small valves in the line are "residual" valves; the 2 lb would be in the front brake line and the 10 lb in the rear line if you use them. The big valve in the rear line is a "proportioning" valve and probably an adjustable one so you can proportion the front to rear brake bias. With front disks and rear drums you need it. The stock single master cylinder has a fitting on its output that the line to the front brakes and the one from the rear screw into. You just need to separate them putting the front line into the larger reservoir side of the dual master and the rear line into the smaller reservoir side.

You never said if the power brake unit is a factory or an aftermarket unit. I'm assuming its factory.

BassMan, I tried to PM you back but the system says" you have exceeded your quota". So I will simply say if you are using the remote reservoir, modifying the floor access hole is not necessary. I did it for easier access on checking fluid levels.

I installed the kit from Jim in my 62. I did enlarge the hole for access, but I was replacing the floor anyway and trying to make life easier on me. I installed the 2lb. in the front, 10 lb towards the rear and installed the proportioning valve.

Much frustration, exasperation has yielded to exhilaration over finally installing the dual m/c (Napa/Raybestos MC 36237) in my 62 GT with drum/drum brakes.

BIG THANKS to “Topper2011” for letting me crawl around under his to figure it out (moving fuel line further left). A couple slight tweaks to the kit made all the difference.

All new lines/hydraulics/DOT5 meant everything came out. Alarm at the condition of the old front crossover line (pictured).

Had I not committed to DOT 5 change, I might not have cleaned and inspected this closely enough! Now I carefully inspect every component I encounter anywhere on the car.

Lesson learned!

THANKS AGAIN ROLAND!
