94 f-150 I6 300 brake pedal releases air
Hello everyone. I have a question hopefully someone out there knows and can help me figure out what’s wrong with my truck. After I park my truck I have my foot on the brake pedal and after I turn off my engine I hear air being released from the brake pedal. For about 4 seconds. Does anyone know what could be the problem?!

Your foot is on the pedal. Take it off.

After shutting down engine(foot off the brake), wait about five minutes and pump the brake pedal. If you get 3-5 "assisted" pedals before the pedal gets hard, everything is fine. If it is hard from the start, look for a leaky booster, its pedal seal, a leaky vacuum check valve or its grommet.
