Chris - any update on the diagnosis/issue with the dragging brakes?
I have EXACTLY the same issue on my wifes '83 911 SC that I am trying to resolve.
Haden't had the car on the road for two years, two calipers were seized. Replaced all 4 calipers. Drive the car for 10 min and all 4 wheels start to lockup/drag (there is residual pressure in all brake lines - I crack open the bleeder and I get a squirt of fluid which released pressure and the wheel turns with no issue)
Or - I let it sit for 15 minutes after a drive and they release (cool down).
replaced the master clylinder last night thinking that has to be the issue - with exactly the same response.
You can tell the brake pedal has less "play" after drving - due to the buildup of pressure.
Any further input is greatly appreciated !
Thanks
Steve
