Question What is the best tool for separating brake discs?

I've done it the wrong way (i.e. by cramming a screwdriver between the pad and the rotor). I've also bought "brake pad seperator tools" at Autozone that bent the first time I tried to use them. So what, exactly, is the very best tool for this job? I figure I'll buy it once and never worry about it again.

Once the caliper is off of the car? I big C clamp worked great for me on my '88. I think it was a 6" C clamp actually.

hmm, if this is for the C4, then you probably have 4 piston calipers. I assume the C clamp would still work, but would be more of a pain unless you used it in conjunction with an old used pad so you could push both pistons on one side down simultaneously.

Channel lock pliers work great. But, if you're a tool snob like KTL here on Pelican, then you'll need the super-special brake pad separator he has. I needed to do an Indy Pit Crew caliber pad swap at a DE, and he whipped this fancy thing out from Baum Tools. It even made the guy with the $100K+ engine jealous.

always use old used up pads w/ clamps, channel locks et al. The piston tops are pretty thin and easily damaged

I bought this tool a few years ago and it works well to fuly retract the pistons. I also use channel locks and squeeze the old pads by holding an ear of the pad and the side of the caliper. This works OK too.

This tool was $50, but well worth it for me since I swap track and street pads back and forth so much.

i have a very simple and quick tool for retracting pistons while the caliper is on the car

i got it from pegasus racing.

i'm drawing a blank on how to describe it... it's a handle the size of an avg. screwdriver length with a flat piece of metal at the end of it. when you hold it for use on the caliper, it resembles an upside down capital letter "L"

you insert the flat part in between the piston and rotor, and slowly twist the tool. this in turn will cause the flat short side to push against the rotor and piston, pushing back the piston. some caution is required to make sure you're positioned on the center of the piston b/c if you apply the pressure at the edge, you might seize the piston but otherwise it is a very simple tool to use AND to make it for yourself from whatever is laying around.

i'll post a pic later.
