Caravan: Both front calipers seized????

 Hello all. OK just to keep it short, my brother has a 1994 Dodge
Caravan with the 3.0 engine and automatic transmission. This may or
may not be relevant to what I am about to ask but at the beginning of
last week he had the rack and pinion changed.   Now he says when he
drives after about 20-30 minutes of city driving the brakes begin to
drag badly so that the van is hard to drive. He said last night it was
so bad when he got home he saw both front calipers "glowing red". I
just had time now to pull of the front wheels and had him pump the
brakes and hold the pedal down and opened the bleeders and both had a
strong fluid pressure so I know the master cylinder is working fine in
that regard. My question is..Is it possible BOTH front calipers are
going bad at the exact same time and if that's unlike what else could
I look at as the cause? Thanks in advance
