Ok guys need your help, bought a set of slotted brakes, a pretty easy DIY, put the two fronts in without any probs, but when installing the rears, i cant get the calipers back on, because of the newer rotors the caliper doesnt want to go back in...
i know i need to push the piston back into the boar, ive tried using a c-clamp, but had no luck apparently i need to turn the piston as well as push it in at the same time....
i need to buy somthing like this.. http://www.getprice.com.au/LISLE-REA...--31462687.htm
but as you can see, i dont really want to spend that much for it....

does anyone know how i can push back the piston by using anything else??

Thanks
Benny
