Abstract
A series of cap members for covering the drive splines of a plurality of carbon friction discs in a wheel and brake assembly to protect the carbon from oxidization. Each of the cap members have first and second tabs that project into the root sections on the carbon disc between the drive splines. The first tabs on the series of cap members are connected to adjacent second tabs to form a continuous ring member which protects the carbon friction disc from degradation caused by oxidation. During a brake application, the carbon friction disc adjacent the cap member engage a portion of the cap member. Thereafter, the cap member and/or the adjacent carbon friction disc are worn away to maintain the oxidation protection after repeated brake applications.
