Hi - time to do my rear brakes. I just wanted to ping the board to see if there's anything unusual about changing pads on the S40 or if there's anything that I need to watch out for (the piston's not going to pop open and crush my fingers, right?) On my A4 it was as simple as unbolting the caliper, clamp the brake piston down, and slap the new pads in.<P>I know I need to find a caliper compression tool (anyone know where I can get one). Better yet, if anyone in the bay area can help me out with the tool and a garage (I have neither), I'll gladly give you something (gift certificates for restauarnant)<P>Thanks for the help!
