A Solution of How to Remove Rusted Caliper Bolt

Hello,

I had a real hard time removing the caliper bolt from my 1993 Geo Prizm
(rebadged Toyota Corolla.) It was rusted on tight. I thought sharing
my experience may help others with a similar problem. I tried the
following before the bolt was removed:

Split/cracked two chrome 6 point sockets. One was a no name brand and
the other was a Snap On (that hurt.)

Various lubricants (i.e. penetrating oil, WD-40, Valvoline Synthetic
Lubricant and PB Blaster.) This was over the course of 6 months and
nothing worked until the following...

What finally did it was a couple of treatments of Seafoam (the spray
can version) in the course of a week, an impact socket on a breaker
bar, and a couple of gentle whacks on the head of the bolt with a
hammer (you don't want to deform the head of the bolt to the point
where the socket won't fit on it anymore.) It still took one herculean
effort to get it to turn. However, once it began to turn I was home
free. The threads on the bolt were so bad that the bolt couldn't be
used again...
