I've been using a kit like this for about 15 years now. I prefer it to the C-clamp method. For me, the C-clamp was always a hassle. Trying to find the ideal spot on the back of the caliper so the clamp didn't slip off. Constantly fighting with the hose getting in the way of the C-clamp. So I like the kit.
The downside to the kit is it really doesn't work on dual and 4 cylinder calipers. So now you are back to a C-clamp, or the pry bar method (No better way to mess up a good screwdriver than to use it as a pry bar). I'm considering getting one of these.

It would be effective for multiple cylinder brakes, and it seems that it would be simpler to use.
