1940 plymouth p9 front brakes disk conversion

[Noonan]

Hi there,

 

Looking into doing a disk conversion on my 1940 plymouth p9.  Does anyone have part numbers handy for the consumables caliper/rotor/pads of some of the kits that have been installed in the past ?

Thanks !

That would be dependent on the kit used.

 

In the download section I added the instructions for the Rusty Hope kit I used, it has that info, for the most part.  I also, in this forum, ran thru my thoughts on that kit.

 

That kit has it's issues, as do the instruction it included.  My thread adds the info it should have and details into issues I saw.

I would draw your attention to a thread titled "Improving Plymouth Brakes"

You might consider adding a brake booster to your brake system. I received the remote booster I ordered from Walmart ( yes that Walmart ) for $63.

I have to tell you it's a real value and a lot less work than installing disc brakes. Some Chrysler models had a very similar remote booster mounted behind the Master Cylinder so it's not a new idea. The one I got is a Taiwanese copy of an American design, VH44.

As is noted in the thread disc brakes require more pedal pressure than drums so you might end up adding a booster anyway to get their full potential.

$63, how can you possibly go wrong?

How well does it work?

Sniper thank you perfect, I checked out your link lots of great info and pics I"ll find the download section and check it out.

 

Loren I've got a 1990 era master booster set up bolted down and ready to go set up for front disks and rear drums.

 

Thanks for all the help

The literature says there’s a 2.3 x pressure increase. The cars I’ve driven have great pedal feel and modulation. As I recall someone said it’s a Midland design. The car I am going to put it on is a 49 3 passenger business coupe. It has 12 inch Chrysler Windsor brakes on the front ( now ) and I am going to put the rears on when I do the booster.

My feeling is you don’t get the full potential without the booster.

If I recall correctly, when I was looking into that specific booster setup it was only good for drum brakes?

Here in Australia there are both a VH40 and VH44 remote boosters that were a VERY common upgrade to drum brake and early disc brake systems.....exactly which booster was for drum & disc I can't recall but these booster are still keenly sought out.........andyd
