I don't think a 10lb residual valve would cause the discs to lock up the wheels. A bit of drag, maybe, but not getting tighter and tighter.

An incorrectly adjusted push rod would cause the problem, maybe made worse by a 10lb residual valve.

The valve causes drag, things get hot, the fluid can't get back to the reservoir so it sets up a vicious circle and it gets tighter and hotter and tighter etc. etc.

Back off the pushrod just a touch and see if that helps. If you have a problem out on the road, just crack off a bleed nipple. That will help temporarily.
