51' Brake Questions

[Slick Steve]

Hello!

I have a 51' Wayfarer and want to change to disc brakes in the front and a dual chamber master cylinder.

Does anyone know where I can get the parts?

Would the master cylinder still be mounted under the floor or on the firewall?

Any tips?

Thanks in advance!

Charlie (Old Daddy) here on the forum makes a kit for disc brake installation, check his profile. Do a search for threads with disc brakes in them. The archives are full of information on disc brake conversions.

Disc brakes work just fine with single chamber MC.

True, but a dual master cylinder is still a good idea! ECI makes a good kit, for use both with and without the clutch pedal.

How about residual valves in the rear lines and a single pot MC ?

Some people swear by em, some at em! What is your Op. Marty?

check whatever dual cyclinder you aim to use if you are placing it in the orignial master cylinder position..most have residual valves built into them..they are also removable...one should have these when changing over..some companies state none is needed for the rear only needed for the discs up front..again that is going to be a question of what one you use...I HAD to install a residual for the rear in my application along with the one for the front disc..my dual master was a 86 Mercury..

I have my kits on sale through the end of the year if you want to do your brakes now. I ran my Suburban on the original MC for years before going to a later style dual reservoir unit. You can run an original MC, but the dual offers that extra safety margin you would want in modern traffic.

1. Can you run a power MC in stock position?

2. Where to tap into vaccum?

Frankie..basically that is what they did with the Plymouth in 1954..there is a large raised bubble in the floor under the drivers seat to make room for the booster...though I do not have the booster on my 54..the bubble is there..I have not looked into this closely as an upgrade but would think the Midland aftermarket 7 inch unit a prime candiate for install...

[Frank Elder]

That sounds good, what about same MC unit stock drums, compatible?

[Plymouthy Adams]

Midland or stock 54?

[Frank Elder]

midland with stock drums circa 1947.

properly installed..not a problem..pressure is pressure..with power booster...less input from you.....applied hydraulics is still the working principle

when I used the word properly..I want to define that piston size of the master for proper feel and displacemnt, residual valve for anti-backflow and even an installed proportioning valve...MP Brakes has a most excellent article for anyone entertian mix match install of components for brake setup on the older cars..I recommend anyone considering this to visit their site.
