My Ebrake is sticking sometimes. I leave the car in first gear and put the ebrake on, if its on over night and especially if its cold out when I come out start the car and back it up I can hear the Ebrake let off after I start trying to move the car. Almost like it is stuck until things start moving... This only seemed to happen after I had the R1 concept rotors put on... Anyone know what might be causing this?

 

This happens with mine sometimes too and I have rear drums. I don't think it's anything serious to worry about

 

Yeah but it's annoying.

 

This section of a howstuffworks.com article on how the ebrake works outlines some of the troubles that may be encountered, including potential freezing of the line in cold weather.

i had the same issue. the ebrake is released off the inside side of the calipers via a spring. yours could be shot (mine was) so i replaced both calipers. cost me about 50 each at vatozone after returning my cores
