[Roadsters] Volvo brake system problem

[Paul Souza]

Hi Everyone,
My brakes stay engaged after 5-10 minutes of driving.  For some reason the
brakes stay enaged enough to slow the car down some.
This problem has been occuring for the past few years now.
 
I welcome ANY ideas on how to resolve this problem.  I have a 280z brake
master cylinder with volvo brake calipers in the front with standard brake
wheel cylinders in the rear.

Thanks,
Paul
