A: Your vacuum pump should not be leaking and ...

Your vacuum pump should not be leaking and should be replaced. The brake booster and booster check valve should be checked to see if they are holding vacuum or if they leak, causing the vacuum motor to run too often. Once the test is done you can find out what repairs need to be done. If you would like to have this done for you, contact a qualified technician, such as one available from YourMechanic, to diagnose your hard brake pedal.
