Calipers for Brakes

Style A

Style B

Check the wear on disc brakes and pads to see if you need to replace them. The jaws are deep and point inward, so they reach around the raised edges on brakes to accurately measure their thickness.

With an LCD display, these calipers give instant measurements—no need to count graduations. Swap between inch and metric or set the position to zero, all with the press of a button.

With SPC Data Output—Send measurements to a computer to store, analyze, and manage data. You'll need a USB data cable or SPC wireless transmitter and receiver.

With SPC Data Output and Zigbee Connection—Wirelessly send measurements to an SPC receiver (sold separately) to store, analyze, and manage data on your computer.

Style B—These calipers have an extra set of jaws to take inside measurements.
