There is a bleed hole in the master cylinder that lets fluid expand when it gets hot. If if is pluged, the brakes will get tighter by themselves. You might put a wire down and clean it out but I would put a kit in the M/C and get it clean. The other possibility is the pushrod is miss adjusted and is holding the piston so for in that the port is blocked.
