I upgraded my F250 booster to F350 Booster & Master cyl. today. My Booster was leaking so I decided to change it out with a F350 system. Ordered a reman Booster/Master combo for a '78 F350 460 auto w/o cruise from O'kragen's @ $107.99 before taxes.

Everything just bolted up to my existing brackets. Brake lines needed to be cut, flared and have the correct ends put on; 1/4in for the front brake (large) reservoir and 5/16in for the rear. Don't forget to unplug your brake light switch or your lights will be on throughout the project.

I wonder why it didn't hold vacuum:

LOL
How come our hands look exactly the same when working on our trucks.

 

Did the same upgrade to mine a few years back. Didn't really make much of a difference though.

I'm still laughing as I type.... Good way to start the day, Thank you! You are correct! It didn't make much difference except my truck is running much better without a huge vacuum leak.... I was going to update this thread this morning with that info now it's done

I'm thinking that for a drum brake system it would increase braking power. Thoughts?

I'm thinking yeah.
I put the set up on my slick and the first time I hit the breaks....woohoo

Right there with ya Marc.. my brakes are very strong, and it takes very little pedal pressure, or throw to get quick strong response....

 

I noticed on both trucks that it reduced the pedal travel and felt more like it was "powered"
