As you know ...... working on brakes can be frustrating especially if you use a C- clamp to compress the piston . But has anyone ever used a Trigger Clamp to compress the piston . It just seems like it would be easier to use than a C - clamp . Lisle makes a tool similiar but costs alot more .

Should work. I push my pistons in with the bleeder open, that trigger clamp may be a pain to clean the brake fluid from every crevice. It would need to be relegated to only automotive, and never used for wood work.
A small pry bar used prior to caliper removal helps. The cheapo screw compressor tool works just fine for the DIYer and won't break the bank.
Use one of these,
A bit heavy but built to last 100 years.

Big old C-clamp is what I use, pry them a little apart while together and C-clamp the rest
It looks similiar to a C-clamp..... heavy , awkward and has the same type of handle which is why I'm trying to find a better alternative . Thanks ThoUse one of these,

There are all kinds of brake pad spreaders on amazon, but an 8 inch regular c-clamp is easiest for me.

I don’t know that a plastic clamp would work at least not for all of them. Personally I like to use the welding style vise grip pliers or the tools made to do it but that’s just my preference.
I've never seen that type before . I shoulda mentioned it's for a single piston caliper .
spent my professional life working as a mechanic and I can always tell the difference in posts between real life mechanics and the guys who do it for fun at home. 
I just jam a screwdriver between the pads and the rotor and pry to caliper pistons back like that.
I do have C clamps, a real brake caliper compressing tool but the good old large screwdriver works better, faster and easier than anything else. no sh!dt, it is that simple.

Huh? You stick the 2 ears of the tool between the inner and out pistons of the caliper and it spreads them out back into the caliper. Not sure how a C clamp would do that.
I meant it's similiar as far as the handle goes and is another downfall to using a C-clamp or similiar tool . I'm looking for something that is quick and easy .
Here's a pic of the rear caliper I have to work with . Part of the problem is : the brake line hooks up on the very rear of the caliper where the C- clamp goes. So essentially the contact area is on the Parking Brake Bolt (black) itself .

Have wanted this Lisle for a long time, the price keeps escalating, but I get by with a few c clamps of the appropriate size just fine.

This is what I use, works great on single piston one calipers and was a bit of a test of grip strength with the Outback's dual piston fronts. I used the old brake pad to make sure I got both pistons evenly and straight.
I use one of those, but I removed one of the swivel pads from the end.
