McCauley Brake Disc Comparison Guide

McCauley wheel assemblies can be identified by their six spoke design as compared to Cleveland wheels which have a smooth dish like appearance.
To confirm you are purchasing the same disc as on your aircraft, count the number of bolt holes then measure the overall depth of your disc from
the outside of the mounting flange to the outside of the wear surface, then compare it with the chart below. McCauley brake assemblies require the
RA066-30026 replacement linings with a whole spread of 1.75”.
