Break Clicks

Mine does that too. I can't hear it when I'm driving, though.

Wait a minute please!!!! What are we talking about here??? Are we talking about the Parking break (Which is a step on brake with a ratchet wheel which has to click when you press it to release or are we talking about the regular brake? I can't visualize anybody driving while shift lever is in PARK

Help, help, help!

The Prius uses electric pumps to provide power assist to the brakes rather than relying on engine vacuum (the engine's not always on, and this particular engine doesn't create much of a vacuum anyway). You might be hearing the relays that control the electric pumps. They're up against the firewall slightly to the passenger side of center, near the top of the dash. Is that where the sound originates?

Thanks for the answers. I'll bet that it's what Robert defined because that's the area the sound comes from. And I was just talking about the car setting still, right after starting and while it was still in Park and pressing of the brakes, not the Park brake. Don't worry I hope to never accidently press the park brake while driving. I did find out though that if you press the park brake(while stopped) before you put the gears into Park your prius alarm start screaming at 'ya. Like Barbara's, mine doesn't click while in drive either. I guess I just never noticed it until a couple of weeks ago. Thanks alot for the replys.
