The Stovebolt Site Forums The Shop Area General Truck Talk Best Dual Master Cylinder for drum / drum - 47-53

What is the best dual master cylinder for Advanced Design pickups 47-53 and drum brakes?

I have a 1952 3100 and want to upgrade the brakes but keep the drums.

I have read the tech article that uses a 1970 and many upgrade kits use mid-late 70s Corvette.

If I want a dual master cylinder, what vehicle do I search for?

Would most 3/16 port MC work? If I ad a 7" booster for power assist, would it be a different MC?

Thanks for taking time to answer a very old question. I did search through 10 plus pages on the bolt for the following search term: 1947|1948|1949|1950|1951|1952|1953 power drum master cylinder

I helped my friend put a duel master cylinder into his '52 3100. It was for a '70 or so Impala (drum/drum). The ones for the Corvette cost more money. The Impala master cylinder is a 1 1/8" inch bore same as the stock '52 master cylinder. The Impala master cylinder has a 1/4" and 3/16" ports. The 1/4" port will be used for the front brakes. The Impala master cylinder, as you are looking from the peddle end the ports are on the left, 1/4" port is nearest to the peddle and 3/16" port is farthest from the peddle end. We did not boost the brakes and we built our own bracket.

The one I used is a RAYBESTOS Part # MC36233, it was used on a 67-69 Camaro among others. It's a 1" bore with 1/2"x20 & 9/16"x18 ports

Thanks, that is great information ! How did you route the brake lines?

I removed the front trans crossmember due to engine upgrade to a 250 6cyl. and 350 turbo
