    Why is there a click noise under the dash??!

    I have a new clutch and about 500 miles into it I have a clicking noise that happens when I press the clutch in or press the brake pedal in. It has not affected any performance or anything like that. The clicking sound is not loud, but with radio and AC off, you can really hear it. Any Ideas?

    Hard to say... does it sound damaging or just a normal mechanical sound (ie, one part interacting with another)?

    no, it doesn't sound damaging...like a mechanical sound, like 2 plastic pieces passing each other. I seems like I can feel it happening when I press the clutch in and apply the brake. It only happens once each application though...for instance, when I shift from one gear to another, the click sound happens when I shift, but if I hold the clutch in and shift to another gear (like deciding mid shift to down shift) it will not happen. It very odd, I'm stumped. It's difficult to describe the sound...almost like when you crack a kunckle or knee when you squat, or when you "crack" your neck. But a soft crack.

    Both pedals do have switches on them. Starter safety switch on the clutch and brakelight switch on the brake. Your probably hearing the relay those switches control.

    Does that mean they are wearing out or is there nothing to worry about?

    Well, it's not indicative of an impending failure/problem so I would just turn the radio up

    I find the relays in my Subie to be on the loud side compared to my other cars. The one that pulls in when I turn on my headlights has been extra loud in both of my WRX's.

    Yup, annoyingly loud. Although I guess it makes it easy to determine when your relay isn't working.

    I know exactly what you are talking about. I get that too when I press in the clutch from full release, but if I hold it in halfway its fine. I don't think I've ever had it happen with the brake pedal. It's like a plastic mechanical click. It doesn't happen all the time, and I think I notice it more in the summer but really can't say. I tried looking to see if anything was interfering and finally gave up. I have an '02 with about 86k on it, and I think I've noticed it intermittently for at least the last 2-3 years.

    Speak of the devil; recalled responding to this thread.

    I recently began noticing how annoyingly loud the switch on the clutch pedal is the other day. Perhaps I didn't notice it before? If it's a new sound I hope it's not indicative of a switch on it's way out. Looks like I'll be turning my radio up as well.

    I've noticed this as well on my 07.

    The clutch from fully disengaged to engaged has a slight click at the top 1/4 of travel.

    The brake pedal has that same sounding click about 2 seconds into hard braking.

    I haven't noticed any malfunction or abnormal happenings other than the noise, however.
