How do you change the rear brakes on 95 del sol?

If it's an si with the disc brakes i just finished doing this on my 95 del sol and i found out the trick to them; you have to use something to push in and twist the caliper piston at the same time, screwing it in like a screw. It has something to do with the parking brake. i got the tutorial from www.Honda-tech.com and I'm just copying and pasting from the site. the tutorial said to use a pry bar like flathead to twist in the piston but i used a pair of needle nose pliers and opened them up a little so the ends were close to the outside of the piston and screwed it in with that. Btw it takes a good bit of force to get it in.

1. Unscrew brake master cylinder cap.

2. Remove lug nuts

3. Remove wheel

4. Using a 10mm socket, remove the two bolts holding the dust shield on.

5. Using a 14mm socket, remove the two bolts holding onto the caliper.

6. Using fingers, remove the brake pads.

7. Using a pry bar like flathead, turn the caliper piston clockwise and push in at the same time to compress the piston.

8. Replace the brake pads.

9. Reverse steps 1-5.
