VCCA Home Forums TECHNICAL - 1945 AND NEWER 1946-1948 1947 stylemaster brake booster questions

Hi
i have a 1947 stylemaster with drum brakes.
This weekend my brakes went out luckily I had fixed the e- brake a couple of days before.
After diagnosing the front passenger wheel cylinder went out so I ordered new cylinders for the front a well as hoses and wheel seals so I can repack the bearings.
I would like to install a dual master cylinder with a brake booster
I found this but want to get options for something that will work

any help is appriciated

thanks

Remember that brakes are a complete system. Changing one component affects the whole system.

There are 2 key areas I would investigate before making the conversion.

What is the normal operating pressure of the boosted dual master cylinder? How does that compare to the operating pressure of the system today? If the pressures are higher, can the rest of the components handle that increased pressure?

The other is the question of pressure balance or bias front to rear. Does the split cylinder provide the same pressure to the front and rear cylinders? What about volume of flow? The current system is designed for equal pressure at all 4 wheels. The braking force is different front to rear because the wheel cylinders are different diameters. The flow volume is distributed based on the resistance provided by each cylinder and the volume needed to move that cylinder to create equal resistance.

From wat I have heard from guys that installed that unit it woks fine.

do you know of another similar booster like this?
the guy sell these has no clues about it.
i asked several questions and he just replies with a stupid non informative answer.
i have looked on the internet for pictures of this installed and found nothing as well.

thanks

Welcome to the world of after-market parts re-sellers!

You might want to go to a Good Guys show near you this year. There will be knowledgeable suppliers as well as lots of cars with this type conversion.

ok thanks

Please let us know if you got and installed the booster and if it works well :
Thank you

looked into this more and it will only work on an auto
it does not have the hole to mount he clutch pedal
im going to convert it to auto so i might try this in the future
