    IMG_4686.jpeg Hey did some searching and did not come up with much

    Is anyone rocking this style under floor power brake booster setup ?

    I was looking at doing this master with 7" booster with 2 -10lb residual valves and the remote master on the fire wall .

    My orig master has too much rust to repair and I wanted a dual master with power booster

    I’ve got one of those boosters and brackets I’d sell if you want to go that way. I bought it and decided not to use it. Message me if you’re interested.

    instead I used a Chevs of the 40s bracket for a modern manual MC under the floor in the stock location.

    I did a 40 with this type setup--miserable. First used a single diaphragm, it and 4 huge boat anchors would stop the thing in 200 yds. Went to a dual diaphragm, better but still kept your attention at any stoplight. Planned a firewall type but sold the car before that. Retrospect--firewall type first.

    Here is how I did it on a 40's Chev pickup. Don't know if cars are the same.

    If you are running drum brakes, I recommend leaving that residual valve out.

    Used this style on a 34 chev. Works fine. Just got an inspection panel in the timber floor to access the master cylinder. Dual diagram booster is awesome.

    No residual valves, drums rear, disks front.
