Hey I got a problem...

While driving my 5kTQ in the summer heat, 95+ degrees, Both the rear
stick after brake application.  The rear callipers are rebuilt V8 units
new pads and rotors.  It happens when the ABS is on or off and doesn't
go away
when using the ABS.  I have noticed if I hit a big bump just the right
way the
callipers let go with an audible pop emanating from the front of the
vehicle.  I
suspect it's either the brake booster or the prop valve, any

It's the MC. It warms up => the piston sticks in the bore => the rear
brakes drag.
If you rest your car, letting it cool down, the brakes should come back
The MC is not rebuildable, just replace it. For your car it was $98 from
Blau last time I checked.
