I own a 2006 Toyota Avalon with 81,000 miles. I had the brakes changed to long-lasting heavy-duty brakes about 20,000 miles ago. When I step on the brakes the car stops fine, however the front end shimmies. What is causing this shimmy?

Check the brake calipers to see if they are sticking; also check for a blocked rubber brake hose that would allowing the brake to release after the pedal has been released. Both of these could cause the brakes to stay applied with your foot off the brake pedal, resulting in a heating up of the rotor(s) and warpage (causing the pedal pulsation).
