I have a 1971 bay window deluxe model with the vacuum brake Assist and every time i hit the brakes The motor goes to stall. Im guessing its the long hose that runs from the front to the motor but is there anyway to bypass replacing that hose? Do i need a master cylinder and cervo? Am i completely Wrong?

NEES HELP LET ME KNOW WHAT YOU THINK!

If the hose was bad, it would cause problems all the time, not just when you hit the brakes. It seems your booster is bad, causing a large vacuum leak
when the brakes are applied.

If it was the hose it would not idle correctly all the time.

If you are loosing brake fluid. Look where the master cylinder mounts to the servo for a brake fluid leaking into the servo. If it is leaking here you need a new master cylinder.

Disconnect the the hose at the servo and plug it. The symptom goes away the servo is leaking.
