Bought Used 4Runner. Brakes pulsated very roughly when applied. Took to Midas for Inspection. $1850 estimate to replace front brake pads and rotors, rear shoes, cv joints and a few "cracked" belts. Took the truck to my mechanic; $650 in parts and labor. Midas lied about the rear shoes needing replacement as they were practically brand new. Belts showed no signs of wear or cracking. Find a good mechanic you can trust and give him or her your business!!!!
Exactly how it says... when medium braking there is a shimmy in the front as the vehicle comes to a stop. I had the pads changed to ceramic and new rotors installed and viola - shimmy pulsation is gone.
