Clunking noise when using e-brake

When driving at any speed, in or out of gear, I get a clunking noise when I pull up on the e-brake. It makes the sound just as I feel the pads connect with the rotors. It may be normal, but wow, it is a serious "clunk". Has anyone else noticed this?

Gotten it, but only when pulling the e-brake when coasting to a stop. I'm thinking it might be somewhat of a sticky cable or something like that. Don't think it's anything serious.

GTOs sit on a boat for a couple of months -- then, particularly with 04s, sit around for months more -- so maybe a lack of lubrication causes a bit of jolt until it's cycled a few times.

That said, it should clear up. If you can continually duplicate it -- best to write it down on your list of things to do the next time your car's at the dealership.

Yeah, my 05 does the same exact thing. I've only tried it a few times so I don't know if it's somethig that will go away with some use on the e-brake or not...

Sorry to say...

Sorry guys. This was the first major thing I looked into when after buying my '05.

This condition is on all the GTO's (and apparently the C6 'vettes to, so I'm told).

I'll look for the thread I read somewhere that explains it in detail, but it is normal operation, unfortunately. Has to do with the *Parking* brake (notice I no longer call it an e-brake) is built into the inner diameter of the rear rotor, and when energized, it clunks majorly on the inner wall if the car is moving.

Why they would put a system like that on a performance car with a HAND activated parking brake is beyond me. But that's just the way it is. Nothing's broken or misaligned...

Again, sorry!

Here's the link to the detailed explanation

Thread over at another board cleared this up for me:
