i need to get myc aliper back on my rotor, but i dont have a cclamp, anyway to put it on?

 

It depends on which one, front or rear. For the front use anything that has a clamping force to push the piston back into the caliper. I've use big pliers, prybars, etc. For the back, they screw in. On the piston edges there are two indentations for a special tool but many can be made to work.

 

Vice grips. Put the old brake pad on, then squeeze the hell out of it.
Might now work though if youve got new rotors and pads, since the thickness is so much more then it used to be, and you cant compress it all the way.

I 6" clamp is only like 9.99 just buy one and not worry about it anymore.

 

Yea, and make sure the brake fluid reservoir cap is off.

 

Or just make sure the little bleeder valve is open, and get a vessel of some sort to catch the fluid that comes out when you clamp it. I also vote on channel locks or vice grips.

 

Don't forget that brake fluid can do nasty stuff to paint and other delicate surfaces... so compress the calipers slowly.

It ain't pretty, but I usually fully compress the caliper piston by sticking a screw driver between the old pad and rotor, and gently pry... then swap new pads... one side at a time.
