How do I know if my brake booster has a vacuum leak?

Vacuum boosters require three basic tests:

At least two brake applications should have a power-assisted feel before the pedal hardens noticeably. If the pedal feels hard immediately, or after only one brake application, it may indicate a vacuum leak or a low level of engine vacuum.

Can a vacuum leak cause squishy brakes?

The quick answer is that a vacuum leak has no effect on the hydraulic system and cannot cause the dash light to come on. Only a hydraulic leak can cause that. A vacuum leak may impact the power brake booster, causing a harder pedal, but not a soft pedal.
