Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

i'm tracking down a noise in my '08 987s. it's a metallic squeak that happens at lower speeds and is relative to wheel speed (not engine speed). Applying the brakes effects the noise a bit, but the thing that really triggers it is parking brake application @ speed. Why would parking brake application feel so different from normal brake? Question: how does our parking brake work? Two most common types: a) applies pressure to the normal rear brakes, or b) operates on a drum brake inside the rear hub Anybody know? For some reason I thought it was "b". FWIW, I leaned on the parking brakes a bit at around 50-60mph to try to burn off whatever rust might have been there. Seems to have a) made them really hot and b) quieted the noise down. Thx!

Thanks, I found this too: http://www.planet-9.com/cayman-chat/18681-parking-brake-repair-photos.html This is just an FYI for folks who are getting the "my brakes make noise after I washed & parked my car" issue, and it doesn't go away by applying your brakes. Somehow I got some moisture into the parking brakes, and they got pretty noisy. We'll see if my sledgehammer "fix" worked (heating them up at "speed"). Scott.
