First Claim
1. A brake disc and drum measuring apparatus, comprising:
- an elongated member having a center axis therethrough;
a first pair of jaws for measuring thickness of a rotor;
a first of said first pair of jaws engaged to said member;
a second of said first pair of jaws, translatably engaged to said member;
a second pair of jaws for measuring diameter across the inside of a brake drum;
a first of said second pair of jaws, fixedly engageable to said elongated member;
a second of said second pair of jaws, engaged to said member;
a calibrated means for axially adjusting said second jaw from said first jaw of said first pair of jaws, and said second jaw from said first jaw in said second pair of jaws, and indicating the extent of distance thereof from a normal or “
zero”
position;
said calibrated means having an electronic display of indica representative of said distance;
said apparatus having an in-use position during employment by a user for measuring either a said drum or said disc;
said first pair of jaws extending generally upward in said as-used position;
said second pair of jaws extending opposite said first pair of jaws; and

Abstract
A brake disc and drum measuring device featuring an elongated member attached to two pairs of jaws extending in opposite directions from the member. A first of said first pair of jaws engaged to said member is adapted to measure a brake rotor while as second pair of jaws measures brake drums. A digital display is always in view with digital indicia right-side-up when the device is being employed in the as-used position with the first pair of jaws extending upward relative to the user'"'"'s face. Large shoulders on a second pair of jaws provide for easy positioning on brake drums having oversized extensions from their sidewall. A moveably jaw on the second pair also allows the device to be balanced.
