Looking for recommendations on a manual hydraulic brake master cylinder for inertia drum braking. 900lb drum.

Going to use a car disk and caliper, but having a hard time sourcing a master cylinder that offers fairly easy mounting and isn't vacuum assist

I used a trailer brake master cylinder and made a bracket with a 1m lever. Cheap as chips and works fine on my rolling road. Rotors and calipers can be had from a car compliance business in NZ for free. I got a 4-pot new-looking Brembo out of a bin

Thank you!

Outside the US there are still a lot of British Lockheed non assisted brake masters in scrapyards.

Inside the US, I'd look at aftermarket race car stuff - Wilwood probably. Dirt car applications would be a good starting place.
