Q: brake caliper don't release

My car: 94' CHEVROLET LUMINA APV MINI VAN
The problem: passenger side front brake caliper just don't release always
sticking in hot weather.
Driver side brake no problem and cold weather no problem. also I already
change 3 calipers still have the same problem. The weather going to warm,
I'm anxious to fix this problem.
Any suggestion will be highly appreciated.
Thanks anyway.

It is most likely the rubber hose:

The hises have a tendancy to collapse on the inside, and hold risiduak
pressure on the caliper. A quick test:

Release the bleeder valve to see if there is pressure in the caliper, or if
the fluid just streams out.

After that, allpy the brakes, make sure the caliper sticks again, losen the
flarenut on the pipe that attaches to the rubber hose if you found pressure
at the bleeder. If no pressure at the flare nut, or very little, the hose is
your culprit.

if changing the caliper did not work(after the first one really) you
need to suspect the flexible brake hose....they deteriorate from the
inside out...once they begin to deteriorate they separate inside and
in effect become a "checkvalve"(one-way valve) internally...they will
let pressure in, but not out(or slowly to let it out)....you can test
this by opening the connection on the master cylinder side of the
hose(when the caliper is "sticking")...if you have no pressure release
there, open the bleeder on the caliper...if you have pressure here the
hose is bad....if you replace one, replace the other side too....any
outer signs that it is deteriorated such as dry rot and cracks, then
replace...

isn't this interesting....guess you are not as stupid as you sounded
earlier...

That could be a bad flex hose to the front wheel. They can come apart
inside and the inside lining can hold the pressure on.
