Does it take a special tool to replace rear brake pads on 2002 hy

Hi from uk the rear brake calipers pistons have to be rotated and pushed backwards into the calipers fully so as to enable new pads to be fitted there is special tool for this to make job easy and if you check E BAY garage/tools and equipment pages there are numerous types and different prices dependant on makers ? however you can improvise/make a tool using a a 1/2 inch square drive socket and t/bar +short extension look at piton and you will see it has slots ? cut away an old socket to provide teeth to fit these slots ? then you can both push and rotate c/wise the piston back into caliper or you can buy the tool ? from motor supermarket if you have time ? hope this helps
