I am having trouble with overheating with my passenger front disc brakes
on my '66 MGB. I have replaced a warped rotor on that wheel, but it
doesn't seem that the pistons are returning all the way to allow free
wheeling with the brakes not engaged. How much drag is normal on front
discs, if any? If the pistons are not returning properly, I have seen
tech tips incriminating the brake hoses. The techy says that if the
inside diameter of the brake hoses is insufficient, it will not allow
fliud to return properly, thus not allowing the brake pistons to return
far enough.
If the brake hoses are too old then tend to collapse, trapping pressure in
the caliper. If the hoses are old, I'd replace them first. Even if it
doesn't solve your specific problem--it might be your calipers are in need of
rebuilding--it still is a good safety move.
