He can remove the booster , the difference in masters is drum brakes vs. disc and reservoir sizing for the front calipers.

What's it take to convert power brakes to manual brakes? manual brakes need a MC with the machined circular groove in the rear piston "thimble" about halfway down for the snip of neoprene retainer on the manual brake pushrod to lock into. PB do not require this "groove" but can use a MC with this groove. all that is left is the bore dia and as mentioned possibly a pedal swap to change the ratio (if needed). if the MC has the groove & it is in good shape I would try it & if the pedal effort and or pedal travel is unacceptable then purchase a different one.

1967 Chrysler Imperial with front disk brakes has a bad power booster. My son wants to use this car in the street class at our local drag track.
What's it take to convert power brakes to manual brakes? Is the master cylinder the same or is there a manual master cylinder that needs to be used instead? Is this even feasible or should he just get the booster rebuilt? If I was you I would have the booster fixed How big is your Son and how strong are his leg muscles? How much does that car (Tank ) weigh I've owned and driven a bunch of the early large body Mopars including several Imperials, none of them would stop worth a hoot with the motor off when towing them I was a lot younger then and I worked for the local telephone company climbing poles every day so my leg muscle where not weak, I weighed right at 200 lbs. at that time so my legs muscle where strong and stout Be safe, fix the booster
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Is it for Halloween or something like that? That is the only way I could see taking a car like that to the race track.

Since a boat like that didn't have manual brakes as an option you'd be stuck either trying to make something, or make something work.
A properly setup manual brake system isn't any harder to stop than a power setup. Pedal travel will be the only difference.
I've had plenty of power and non-power braked Mopars, both all drum and drum/disc setup and never noticed any difference in how the brakes "felt". Unlike Chevys which were very noticeable to me.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
