I believe the facts point to the TreadleVac as being a completely reliable power brake booster, though of course lacking the extra security of the later "dual cylinder" systems.
That last line is of central importance to this discussion, IMO. The TV is probably as reliable as any other
single MC braking system... but that's the point: it's still a single system, with no backup. This is a drawback for anyone driving a vehicle that predates the standardization of dual braking systems in the late '60s. This includes manual as well as power brakes.
Now, if you could, or would want to, somehow modify the T/V to operate in a dual braking system, it would probably be as safe as any other dual system.
Also, to get the most safety benefit from a dual braking system, you need a warning-light to tell you when half the system is down (you can drive a long time on half your brakes and get "used to" the difference, mainly when it's the rears that have failed).
I'd be interested to know if the conversions some have made to dual braking have included a warning light system, and if so, how they did it. Do new off-the-shelf kits include this feature?
