Not sure what you mean by "screw in". Just put the old pad against the piston and use a large c-clamp to push the piston back into the bore. Please note I have yet to change the pads on my 9-3, so this is based on changing pads on many other vehicles.

Good luck!

 

I know the c-clamp thing won't work.........as when my friend and I tired doing these rears we got stumped at this point also.

Perhaps some sort of push in and screw????

We have discovered the secret. In addition to the screwing, the e-brake needs to be pulled. :roll:

What kind of screwy design is that?


Thanks for the quick replies!

 

There are at least two older threads that cover this.

The pistons screw back in. There is a special Saab spanner wrench which grips two indentations on the visible part of the piston. Maybe those are notches instead of indentations... my Memory Cathedral is being power-washed at the moment, so things are a bit hazy...

Anyway, before you shed a river of tears, take heed. You don't really need the Saab spanner. You can use needle-nose pliers held open, or some other span tool to do the job. One time my brother and I sat 180 degrees apart and used two sets of hammers and screwdrivers in lieu of a span tool. In retrospect, that idea would have been slightly better with fewer beers and more safety goggles, but it worked!

You'll find a way to screw the piston. Snap some pix, if you don't mind. I'd like to see this thing.

 

I picked up a tool for this years ago when I had an old Integra. It's a cube about 1 1/2" square with six different pin combinations, and the center of each face is a 3/8" socket hole. I thought I snapped a picture of it, but I cant seem to find it right now. Look in the tools section of your favorite auto parts store...
