93 silverado... i noticed my brake pedal was feeling softer and when I checked the brake fluid resevoir... brake fluid was leaking out around the cap and was running down and dripping on the ground. This had happened one time before when the shop bled the brakes and overfilled it... but once the excess brake fluid leaked out it stopped doing it.

Now its doing it again and I never filled it with brake fluid. Could the gasket on the cap be mad?

 

worth a try to get a new cap and gasket

 

The gasket and cap look normal to me.
