Subject: Re: Parking Brake and Oil Leaks ( Long Post )


Doug, Yes there is an adjustement at the calipers. In the caliper there is a piston. That piston, on it's face ,has 2 little holes that a Saab special tool fits into. You use the tool to turn the piston so with the pads back in place, the rotor juts turns freely. Turning the piston moves it in and out acording to haow you turn it. Make sure you have pushed the piston into the caliper as far as it will go before you make the adjustment. This adjustment sometimes gets out of wack after many miles or may have been done wrong or not at all, last time pads were replaced. I think the book calls for .002' or so clearance between each pad and rotor. It is possable the cable operated handbrake mechisim in the calipers is not working cause of rust or something. Do the adjustment and see what you got. The tool is cheap at a Saab place or borrow one. Nothing else will work worthe a dang. Make sure the pads are not worn out. Make sure the cable system works freely, not frozen cables ect. Any more questions,just ask. Fred R.
