I read an article in a recent Street Rodder magazine that has me intrigued. They used a master cylinder in the stock location using the stock pedal, which was plumbed to a slave cylinder that operated an ordinary vacuum booster/dual master cylinder in a remote location (under the passenger running board). In the article they used a dual master cylinder in the stock location, which required the use of two slave cylinders tied together to push the rod in on the booster.
Using the dual master cylinder in the stock location to run two slave cylinders seems a little redundant to me. There are LOTS of medium duty trucks with hydraulic brakes out there that run single master cylinder and a hydrovac. The hydrovac then boosts the line pressure and sends the brake fluid to all braking wheels. There is no 'dual system' on these trucks.
I think there are definite safety atvantages to running a dual system, as have been explained above. I have been seriously considering using a new stock master cylinder to operate a slave cylinder that would operate a booster/dual master cylinder in a remote (easier to access for service) location. I need to do some more research on this idea, but I would like your input on this idea.
