IMHO some ""tools"" now made are just to get more money out of your wallet
like this one for example...

thats for the fixed pistin caliper... like mid 90s and older
what happened to the 8inch C clamp that has been used for 40 years or so
C-clamps won't work on pistons that have to be rotated, but I suppose neither would that particular tool. A piston compressor is a great tool to have, but only if it rotates. Though, I have to admit, I usually just rent one from the auto parts place when brake duty comes along.
On other matters, I've found that pickle forks are more trouble than they're worth. The BFH has always worked for me (though I guess in some instances, I'd rather use a puller).
