CLAVIS tool for drum brake setting:
A typical CLAVIS drum brake setting tool, locates around the brake drum. A sensor probe is loaded through an access hole in the brake back plate. A spring loaded sensor probe contacts with the brake lever and is therefore able to track the movement of the lever.
The calibration jig features the actual drum brake. A dial gauge measures lever movement. The calibration accuracy of the CLAVIS tool can be verified either by manual advancement of the brake lever, or by an actual 'set' using the closed setting operation of the system.
The sensor pin is fully enclosed within the tool when not located onto the brake. Only when the tool is correctly positioned around the drum, may the sensor be 'loaded' forwards through the access hole in the back plate.
