Problem with brake heating up

Hi guys, have a problem with my V70 P2 2001 2.4i. I was driving home, a
13 mile journey when towards the end, after a fast bit, I flt the car
start to quiver, as if one rear wheel had thrown its weights, it became
hard to maintain speed on a light throttle. I was sure I'd had a
puncture so I pulled in once I found a safe place.
I got out the car and walked round it to check things. The rear nearside
wheel well was pumping out smoke, pad material stinking and the disk was
glowing cherry red. I let the disk cool befoe I moved off again, did the
final two miles to the house at @30 and disk was dull red when I
stopped. Only thing different was that I had to pull the handbrake lever
up a lot more for it to be effective
Left it overnight, but had to go to work next morning at 7 AM. I drove
like Miss Daisy for the 13 miles to work, set the handbrake which went
up about 10 clicks instead of the usual 5 clicks, I checked the wheel
which was cold to the touch and no cherry red glow. I have had to do the
same journey for the last 4 days, with no time for taking off the wheel
for a look, with no overheating issues. I haven't readjusted the
handbrake or done anything at all.
My main question is, is the problem coming from the handbrake shoes
heating up the brakes, transferring heat to the disk and making the
caliper stick? It hasn't stuck since and the brake pedal is firm with no
travel to suggest a sticking caliper. I have ordered a new caliper
anyway, on the assumption that if it gets warm, it shouldn't jam, so it
is probably on the way out.
Could a too tightly adjusted shoe make the whole thing heat up enough to
make the caliper stick?
I can't take a look at the state of things for another 4 days, but it is
all running OK at the moment.
