I recently attempted to replace rear pads and rotors. After backing the piston adjustment screw back as far as it would go, I still did not have the clearence required to get new pads to fit over new rotors. Am I missing a trick? Oh the car was an '89 900S

I seem to remember having the same problem on my 1990 900S. Try backing out the screw as much as possible, then use a C-clamp and an old pad (or block of wood) to press the piston into its bore.

This is what I normally do when working on brakes (the ole' c-clamp trick) but I guess I was afraid to try because of the nice screw intended for the job that Saab has. Thanks for the advice, I'll give it a try. Oh I also just graduated with a teaching degree in earth science and noticed you are a professor of astronomy. Like all teachers, (well, looking for work teacher) I'm always cool ideas for class.....


Thanks, Rick

I think the screw adjusts a stop for the piston, rather than pulling the piston back into the caliper.
