This OEM body tool is used to identify an accurate measurement of how much brake lining is left.
Works on 2004–newer Ford F-150 pickup trucks with 5.4L 3-valve Triton V-8 engines. The socket end is 9/16 inch and the rubber insert holds and protects spark plug. Extra-long so it reaches down spark plug tubes into the cylinder head. The socket has 3/8 In. drive for use with a ratchet or breaker bar. Constructed of chrome vanadium steel for strength and durability.
