A couple of times in the last 6 months both rear brakes on my 95 525i ( 141Kmi) have locked up. It appears that the brake calipers binding but I thought it stange that both sides would behave the same way, locking up at the same time. Usually if the car sits then the pressure on the pads subsides and the car is drivable agian.

I have replaced the brake fluid at regular intervals and serviced the brakes myself. Other than rebuilding or replacing the rear calipers, any other suggestions?
