Hey Fishguy--I drive a recently purchased 2002 Lexus SC430 and needed to replace the brake pads. I ordered OEM, Japanese, pads from www.autohausaz.com for $85, no shipping cost. After installing them I had a hard shimmy between 55 and 40. I drove about 600 miles and no better. I took it to the Goodyear store this morning and they resurfaced the rotors. I drove about 100 miles this afternoon and the braking is perfectly smooth...no shimmy, bounce or anything. Drives like a new car. I suggest you do the same and your problem will disappear.--Roger Silvey
