It mounts between the Master Cylinder and the Firewall. Mount the booster to the firewall and then mount the master cylinder to the booster. You then need to find a vaccum connection for the booster. You might want to find another Mustang of this era and see how and where the vaccum is connected.

The brake booster is what gives you power brakes. In the engine compartment in front of the steering wheel is a round black flat ball looking thing.

If the vacuum leak is small, then yes the brake booster will still function well enough to assist the braking action. However, if the vacuum leak is very large, or if the brake booster rubber diaphragm is ruptured , then the brake booster will be inoperative and you will NOT have power assist to the brakes. It's wise to just replace the power brake booster with a new unit if there is an internal leak in it, to avoid an accident due to a loss of braking power.
