Parking break sticks after car wash

I'm sure this is a minor deal but thought it best to ask if others have the same experience. After I wash my 997 I usually park it in the garage with the parking break on. If I don't drive the car for a few days afterwards, when I take the parking break off and try and back out of the garage the parking break seems "stuck" on and makes a loud pop as it breaks free before I start to pull out. Is this normal? Thanks for your replies.

I am new here, but yes that is normal. I have a fairly long driveway (200 yds) and after I wash my car I drive to end of driveway with a little bit of speed 30mph brake turn around in the street and then put it in the garage. Drys the brakes and eliminates that popping sound you are talking about. Also keeps them from getting that rusty look after a wash.

Perfect. Thanks. I wasn't going to mention the rust on the rotors, but that is there too.

I have the same, however, it even happens if I don't engage the parking brake....scared the hell out of me the first time. They way I solve it is when I drive the car into the garage I step on the brake and drag them on the pads as I park. Never have the problem anymore.

Rust is normal...wouldn't worry about that.

Yes, it happens anytime the car parks with moisture. Frankly, it happened to me all winter with just the regular brakes. A rust-bond required a little heave to break free. No biggie. Whenever their is significant moisture I try gear holding instead of parking brake just because the tolerances are so close it rusts-together so frequently.

ebreak are inside the inner part of the rotor..they don't use the outside break pads

but still the sticking and "pop" are ok when you reverse out?

you could call your dealer ask if there any service bulletins about that problem.

Yes....... Activating the parking brake handle pushes the parking brake pads (as mentioned above) against the inside of the rear rotors. Pure metal rusts easily on brakes. The rust creates the bond between the forced contact of the activated parking brake. When you release the parking brake, the normal spring-activated withdrawl of contact is prevented by the rusted bond. The "pop" in reverse or forward is required to break the rusted bond. Once it is "broken" the spring retracts the parking brake pads to their normal standby position.

In other words, it's normal, don't sweat it.

My supposition why it happens here more than other cars is that the tolerances between the pads and rotors are much narrower allowing for faster braking and thereby encouraging a rust-bond. But that could be total BS since I made it up.

Thanks. BTW, I'm from St. Louis (Chesterfield, actually). Hope you weathered the storms OK. Talked to my parents and they said it was a non-issue for them but up north near the airport looked terrible.

Faired well but pretty wicked weather. There's a video on Jalopnik about some people screaming through the concourses; academy-award drama efforts. The Japanese sit calm through an 8.0 and, well, it's amusing.

This happens to me EVERY time it rains outside and I pull into my garage. It sounds horrible but you just have to convince yourself that its normal..
