    Show of hands please, how many of you are running single bore brake master cylinders and how many of you are running dual bore or twin brake master cylinders? I am stepping into my second build and am womdring about this. Safety is the concern. Thanks.

    I updated to a dual resivoir master cylinder when I switched to front disc brakes on my 63. If I were doing a factory correct restoration I would have stayed with a single, I drive mine whenever I can, so it just made sense to upgrade just for peace of mind and saftey reasons. I guess if you replaced the cups on a regular basis and changed the fluid regularly it would be pretty reliable. I still remember my Aunt driving a 65 Biscayne which had the single resivoir master cylinder. She drove right thru the carport one day when the brakes failed.

    Sorry not really answering you question,
    but if you used a dual, would you use a
    booster ?

    im about to change my brake system and
    was told you really dont need one if i
    was to go dual master.

    Im thinking dual beacuase i can fit it
    some where else instead of the firewall.

    Dual on all three vehicles. Was not always so, but doesn't make sense to run the singles.

    I never had issues with any of the cars/trucks I had with single..

    Until this past summer I was sitting in my buddys driveway, which has a decent incline, and all of the sudden, poof...while at idle and in reverse, the pedal went to the floor and I was rolling quickly backwards.

    As I tried to reach the ebrake, I went down, across street, between 2 parked cars, into yard across street missing a tree and fench, through another yard and back onto the street, all while going backwards.

    I grabbed the ebrake finally, checked my shorts, checked my pulse and took a deep breath.

    In hind-site, I shoulda threw it into drive and gave a alittle gas to stop the rolling, but it all happened in seconds...

    This in a vehicle I had just driven almost 500 miles to a Goodguys show.

    Now, for what little effort there is, Im going with dual m/c just to at least have some brakes if a wc or mc goes.

    Switching from single to dual chamber hopefully this weekend. If for no other reason, do it for the safety factor. And if you dont, a functioning parking park is an absolute must. I learned this the hard way when a organial hardline went out on my Buick. They stopped making them like that in 67 for a reason, right?:confused:

    i stayed with the single...just make sure everything is new...master, wheel cylinders, lines, hoses..having stick shift is always a plus.

    Dual cylinders, power and manual, are available new from your local auto parts store for drum/drum and drum/disc brake setups.
    Most cars from about 67-72 or so could be had either way and with or without power too.
