Hissing Honda Odyssey

Our van hisses intermittently when letting off the brake. It has gotten really obnoxious lately. The pedal also occasionally gives way slowly when at a stop. My first thought was the booster but it passes all of the tests in the manual. Has anyone else come across these symptoms? Regards - Cory Gill

It may pass all the tests in the manual, but is one of those tests ‘operates without hissing’?

BTW, what year is the Odyssey?

Surprisingly, no, it wasn’t. It is a 2000.
