Yesterday I was having a nice drive on the freeway when I tried to slow
down only to find the brake went solidly to the floor. The fifth time I
pumped the peddle I finally got about an inch of peddle, the next time I
hit the peddle it was fine. This made for a kind of shaky situation due
to the brake lights in front of me. For the rest of my trip it took 4
or 5 pumps to get the peddle off the floor. When I arrived at my
destination I had one wheel that was excessively hot. Later in the
evening when I made my return trip home the peddle had returned to
normal. For most of the return trip the brakes seemed ok but maybe
dragging a little from the one wheel that had gotten hot. When I was
almost home I felt the dragging go away! Today the brakes seem fine and
the drag I felt earlier has completely gone away.
What are the odds that overheating the caliper broke free any buildup
and now that it is cool it is operating normally? I am going to change
out the brake fluid in case I may have moisture or air in it which may
have caused my failure yesterday. The important thing is no brakes in
traffic and not getting in an accident.
One more item, my '78 has very poor brakes normally. Could this be due
to the quality of disk pads?
