I am buying a 1937 plymouth sedan and i am thinking about changing the engine or modifying the original. My question is what should i do with the original hydraulic brakes? should i change them regardless or should i only change them if i put something over 300hp in it? This car will not be a daily driver just a toy.
If you decide to go with a disc brake conversion give us a call we have a bolt on kit for the original spindles, and a dual master cylinder conversion. 860-872-7046.
there are several options for disc brake conversions. There has been much discussion of the subject try doing a forum search. Check out member Old daddy website for one of the options.
The stock brakes **** even completely rebuilt. Put the disk brake kit on, use the stock master cylinder, and stop with confidence! You can open up the stock wheel lug holes a little bit and they will fit the chevy 4 3/4" disk pattern, the center of the chevy hub will index those artillery wheels nice and straight. Been driving this Dodge like this for years. You'll drive the car a lot more when you feel you can stop.
It cost me nearly as much $ and time to rehab the drums on one old Mopar as to discs on another. I say do the discs
http://www.jalopyjournal.com/forum/showthread.php?t=257063 I used the old daddy kit on mine and was pretty happy. Good guy to deal with....
I didn't want to mess with my 47's drums (special tools, major pain to setup), so I took it to an old-timer shop. A week later, he tells me that for 150 more, I can have discs and a dual master cylinder! That's shop prices! Go for it!
I ran the stock front drum brakes on my '48 coupe for a couple of years, part of that with the stock rear end and part with a Ford 9" rear. They were terrible either way! Not even close to being safe. Went with a disc conversion for a while using Dart front discs as I recall, which was a big improvement. The bottom line? Do something...ANYTHING...other than keep the stock drums! ECI makes a nice bolt-on kit for these cars, as I recall, and is probably a very good choice for a daily-driven car that needs to be safe, not fancy. Just my $.02
