You dont compress a piston with a C clamp, you use a piston ring compressor to compress the rings and tap the top with a hammer to sit it back in to the cylinder bore. The C clamp is used for compressing valve springs. *AArOn*
You can use a large C-Clamp to compress the caliper piston.
Brake piston? Front use a "C" clamp to compress Rear - Piston is threaded turn clockwise to compress (water pump pliers?)
On the fronts, you can use a C clamp to compress the piston but the backs you have to screw the piston in, don't use the C clamp because you will screw it up, they sell the small tool that you use to screw in the piston at any auto parts store.
Shade tree mechanics use a C-clamp and a flat steel bar to compress the piston. I have also used a large adjustable Channel-Lok-type pliers to compress.
Use a "c" clamp to fully compress piston into caliper body
use a c-clamp and push the piston in that way. style c-clamp i sue http://www-ece.rice.edu/~jdw/figs/c_clamp_2.jpg
Use a C clamp to push the piston out of the way to remove and also to place back on rotor.
with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.
To compress a caliper piston, you can use a brake caliper tool or a C-clamp. First, ensure the brake fluid reservoir cap is loosened to avoid pressure buildup. Then, position the tool or clamp against the piston and the back of the caliper, and slowly apply pressure until the piston is fully retracted. Be cautious not to damage the piston or the caliper during the process.
Similar to any other caliper piston, you might used a C-Clamp that has been covered in some protective coating to prevent it scratching the caliper. Ideally the C-Clamp would not directly compress the piston edge but some piece of flat metal, laid out in a way that would allow it to spread the force across the piston's diameter.
use a large c-clamp aiso use the old brake shoe on the caliper piston to squeeze it back in
To compress the caliper piston on a 2007 VW Rabbit, you’ll need a brake caliper tool or a C-clamp. First, remove the caliper from the bracket, ensuring you support it to avoid straining the brake line. Then, place the tool or C-clamp over the piston and the back of the caliper, and gently compress the piston back into the caliper housing. Make sure to check the brake fluid reservoir, as compressing the piston can cause fluid to overflow.
