Another issue: some people with original (read: old) rubber brake
lines have them fail internally and act as a restriction to the system.
The force to apply brakes goes by the restriction, but it doesn't
fully release the pressure in the caliper, leaving the brakes hanging
up. As the brake drags, the rotor heats up, and heat runs into the
caliper, causing the fluid to expand; generating more pressure etc. and
the caliper grabs the rotor even more firmly.
Moral: consider replacing the rear lines if they're looking old and
swollen.

Great, I thought it was an even F/R bias, so if the left was free so
was the right. I'll try and see if this is the cause. The condition it
is trying to save me from is very unlikey to occur under my wives
stewardship that if it is determined to be bad, I think I'd bypass vs
replace.
thx
