Question about 2006 Ford F-150
I have a 2006 Ford F-150 Suprecrew 5.4L 3V that is shuttering when I brake at speeds of more than 40mph. I replaced the pads and had the rotors turned prior to the problem beginning. Any solutions?
You need to have rotors machined on the truck. Can have no more than .003 runout after machining. Off car lathe can not do that.
More than .003 run out will result in rotor thickness variation and shudder as the variatons pass through the camped brake pads.
I workd on this industry probelm in 1989 when suspensions became too sensitive to runout and thickness variation.
Find a dealer or shop with on car equipment.

try doing a spark test to insure that you are getting a good spark if you have a good spark then i would try doing a tune up and replacing the pcv valve and if you have a check engine light on go to a local parts house and have them do a obd2 scan and see what that comes out to be because it could also be the egr system hope this will help you out please leave a review thanks sincerely D.Jones
