One thing I haven't seen addressed on this subject is the
Front flex lines. There has been quite an ongoing discussion on the
Spitfire list about this, and I just had it
Happen to my 89 Voyager van.
An old flex line between the car and the caliper can
Deteriorate and collapse internally. When this happens,
as you step on the brakes, the pressure builds up on the
lines causing the flex line to balloon and allow pressure
to the caliper. When the pressure is released, the flex
line returns to normal, except the inside tube is blocked
off and the pressure can NOT be relieved on the caliper.
This causes it to appear that the caliper is "stuck". This
Can cause premature pad ware, overheating of the brakes,
Etc, etc.

Lannis,
The calipers cannot cause pressure in the system. Only the failure
of the
master cylinder piston to return fully will cause that problem.
Caliper
pistons can surety stick, but very rarely would they both do it at
the same
time, and opening a bleeder would not help in that situation. Be
sure that
your pedal returns completely and that there is very little free
travel in it
when it has returned. If you look into the reservoir while someone
pumps the
brakes a few times and then gets off of them you should see a spurt
of fluid
rise in the can. This tells you that the piston has returned and
the
compensation port is open.
