Hi Everybody-Have a bit of a situation that I am hoping someone might be able to shed a little lite on.
I took my 850 out for a spin on the highway a few days back (for the the first time in several months). It was a very hot and humid day and after several miles the brakes started to engage on all 4 wheels getting progressively worse until the car was very difficult to drive. I was able to limp it back home and put it on a lift where I verified all 4 wheels were locked up from brake engagement. After leaving the car overnight the brakes released and I am able to turn all wheels by hand again (with car off the ground). Have not been able to find a lot if info about this other then one old roadfly thread.

I will start with a complete flush and bleed of the brake system but other than that not sure what direction to take it...so any advice would be as always greatly appreciated.
Thanks-John
BTW-ABS seems to be working properly and the brake pedal pressure also feels normal. The above thread suggest Master cylinder replacement but my experience with master cylinders is that they usually fail with no or low brake pressure not too much brake pressure.
