Caliper rebuilding tools

[Texas Don]

Is there a tool for spreading the dust boot prior to inserting the piston in the caliper bore? I followed BassCliff's recommendations and with a lot of swear words, 1 jalapeno chili dog, 2 beers, more cursing and 2 1/2 hours, I finally got the $%&$*# thing installed on one side. I made a couple of changes to his method while installing the second one. I made a small hook out of 13ga. solid copper wire to lift the edge of the boot with, and I installed the boot on the piston and let it sit for about 1/2 hour to slightly stretch and relax it. The second boot was on in less than 5 minutes. I can't imagine a factory worker or even a commissioned technician going through all of that to assemble a caliper. I have seen boot spreaders for automobile brakes. Anyone?

Hold the caliper piston over the installed caliper boot and direct low pressure shop air into the brake line port. the boot will go around the piston.

Best method I’ve found is to install the boot over the piston with the boot slid all the way down to the bottom – don’t use any brake fluid on the piston or the boot will slide right off. With the boot overhanging below the bottom edge of the piston, clip the boot into the groove on the caliper. Once the boot is in place on the caliper, press the piston into the caliper bore and engage the edge of the boot into the groove on the piston. Once you do it once, it’s pretty easy.

Ed's method is the easiest. Alternatively, if you can find them in the US (we've got 'em over here), fit stainless pistons then you don't have to worry about the boots (or rust) ever again.
