I'm a little frustrated with the search feature. I don't want to ask a bunch of dumb questions that I can search for myself. I don't even know how I should "word the search". So I'm just going to ask - With a disk brake conversion, are there any "rules" about which brake master cylinder to use? I'm thinking about flow rates, maybe gpm, things like this. And what valves they need, (proportioning valve?) And where. Would a stock (original) master cylinder from an f-1 operate disk brakes, (effectively)?

Thanks,
Tom

 

Whenever you're talking about brakes, there will always be rules to follow. Many of them get broken pretty consistently it seems.
Number one, the stock, original master cylinder from an F1 will absolutely not work correctly with disc brakes. It's small size and single reservoir makes it barely adequate for the system it was designed for, imho. It doesn't come close to meeting today's safety standards.
Number two, disc brake calipers need a lot of fluid, and fluid transfer. That's why you'll see m/c's that are for front disc/rear drums have a disc side reservoir about 3 times the size of the drum circuit.
You might find some study material here...Disc Brake Conversion Kits | Master Power Brakes
or here...SSBC Performance Brake Systems

 

Thanks for the reply! Exactly the answer I was looking for. The first link I couldn't get to work but the 2nd link is enough. Go is a good thing, but sometimes STOP is even better!

Thanks again,
Tom
