The brake booster check valve could be defective. This is something easily overlooked. To check, remove the valve from the booster and disconnect from the hose supplying vacuum.

Those born on the Virgo-Libra cusp enjoy beauty and all things sensual. They may find themselves drawn to the arts, attractive people, and precious objects or wish to make themselves and their surroundings more pleasing to the eye.
Libra governs partnerships, relationships and close associations. As a cardinal air sign, Libras are objective and work from the mind, initiating communication.

Relationships thrive on equality.
