Subject: Re: can't get front brake pistons back into caliper (changing pads)

In article <6gefmt$kud$>, says... Adam, I experienced this same dilemma. The Haynes manual is correct. I took a 1/16 piece of flat aluminum that was 3/4 inch wide and drilled two holes, spaced the same distance as the holes in the piston face, near the end of the aluminum. I then threaded these holes and screwed in an 8/32 round head 1/4" long screw. Using this tool you have to turn the piston in clockwise a 1/4 turn at a time and then use a large screw driver to pry the piston in. Then repeat the 1/4 turn with your tool and pry again. I had to repeat this process about 20 times because my pads had been worn so badly. This is only necessary on the inner piston. I think the reason they are like this is the front brakes are also used for the parking brake and this is the only way they could be made and still function as reliable parking brakes. It isn't too bad if you take the time to make the tool. JC > A friend of mine is changing out the pads on the front disk > brakes of her mid-late '80s Saab 900.
