i would, your never supposed to depress the brake pedal with it off the rotor. If you were changing pads there was no reason to press the pedal at all. You step on the brakes AFTER you put them back on. And your fluid level came up because your new pads were thicker than your worn ones, which is normal.

Yes its possible that you need a new caliper because you blew the piston out and probably ruined the piston seal. If it went back in that easy then me thinks thats the case. But it doesn't hurt to try vacuum bleed that caliper to get it full and see if it leaks, sometimes we just get lucky, but make sure its INSTALLED first.

I only did the front.
nothing was touch on the back.
I took the pads off. Painted the calipers.
clam the pistons on the driver side in. put in new pads.
my brother told me to pump the brakes to get the air out.
I pumped while my e-brake was up.
one of the piston on the pass side flew out and alot of fluid came out from there.
i pushed the piston back in. clam the pistons in and put in new pads.
now my brake padel is so light.
thnx all.

What is clam??
I would never listen to your brother again. There was no reason to pump the brakes until you have everything done and back together. The LAST thing you do, is crank the car and pump the brakes. There is no air in there anyway, the only reason you pump your brakes after changing pads is to get the piston to come back out slowly and press against the new pads again without pinching the seal and to get some pedal back....

if the caliper is bad it can be rebuilt, its not too difficult. just a couple of o rings and a a rubber dust cover. you dont need a new caliper...... they sell rebuild kits at the autoparts store.

you will need a new caliper... while your at it to tell you the truth. i'd just go with the cobra brake setup since your about to spend alot for
a caliper and you can just return the pads back to get the whole front system.
