Yeah I got into my rear brakes and found one cylinder leaking.  In a
hurry, got 2 cylinders from FLAPS and put them both on.  Discovered
this terrible problem.  Made the video.  Put my original non leaking
cylinder back on and returned the cylinder.  I left the one FLAPS one
on until I could order proper new ones.  Now that I think of it, this
situation shouldn't account for the temp difference between the rear
drums.  Neither side is going to do much braking until the slack is
out of the system.
