Been dealing with a steering wheel shimmy as well as general shakiness under braking in the Taurus. Coming up on 80k with the original fronts, I figured it was time for a change. Knowing the brakes are a sore spot on the SHO, I picked up the Power Stop drilled/slotted kit for the fronts. Put it on a couple weeks ago and bedded them according to directions. Lately I've been having the steering wheel shimmy under light braking over 60. Also get some weird vibration felt in the seat of the pants too. Around town 100% perfect. Hard stops, mostly OK. Could the rear disks be causing some of it? Looking at them, I can see many (4-5) spots where the pads have deposited on the rotors from the parking brake (on this car it doesn't have the parking drum). What else could be causing this? Have heard sometimes it's suspension - bushings, tie rods, etc but she tracks straight and true and no funny noises over bumps or turns... Plan to pickup a dial indicator and check runout on the fronts to see if I have an issue there either from the flange (I did clean it) or a rotor defect. Anything else to check?
