Feel (carefully) the relative temperature of all four wheels
in the area of the center of the wheel. If one is very hot
compared to the others you may have a sticky caliper.
This is relatively common on older vehicles when
having just installed new pads. Corrosion builds up
on the cylinder wall of the caliper and when you compress
the caliper to install the new pads you force the piston
back over the corrosion, where it has not been for a
long time, and this can cause the piston to stick or
seize. If all wheels are equally hot, then perhaps it
might be the MC. I just had this same problem (caliper)
on the '84 4000Q after installing new rear pads, one
caliper stuck and was instantly diagnosable via the
relative wheel-time trick. New caliper was required.
