A gage includes an elongate support arm at the end of a bar on which there is mounted a measurement and display module. A sliding anvil arm is spaced from the bar in parallel relationship and mounted on the module for sliding movements therewith on the bar. A right angle support arm extends from the free end of the elongate support arm, anvils being mounted on the free end support portion of the right angle support arm and at the end of the sliding anvil arm, both the anvils being arranged along a measurement axis. The support portion of the right angle support arm and the anvil mounted thereon together have a dimension along the measurement axis no greater than the smallest anticipated space between a wheel and a rotor to be measured so that the anvil may be positioned on one side of the rotor while the sliding anvil arm together with the module can be brought into abutment against the other side of the rotor to provide a reading of the thickness of the rotor without removal of the wheel from the vehicle.

An adjustable gage is provided with a plurality of pairs of depth stops along the jaws or arms which support the pointed anvils which contact an internal or external cylindrical surface. By adjusting selected depth stops, an either retracted or extended positions, one pair of depth stops engages a rim or abutment surface of a cylindrical member, thereby insuring that the measurement anvils will contact diametrically opposite sides of the cylindrical surface to be measured along a plane which is substantially normal to the axis of the cylindrical surface. This avoids oblique misalignments of the gage and assures precise measurements.

Gage with adjustable depth stops for measuring distance between two

A linear measuring instrument having a pair of measuring tips mounted on respective jaws moveable relative to one another along an elongated beam particularly adapted for measuring inside dimensions has a digital display unit responsive to display increments of movement of one jaw relative to the beam on which the jaw is slidingly mounted. The pair of measuring tips are spaced from one another, when the jaws are in engagement with one another, a selected calibration distance. The end user of the instrument follows a sequence of steps, including resetting the display unit to read zero and then adjusting and fixing the position of the other jaw to the beam until the selected calibration distance registers on the display unit.
