Rotor Surface Treatment & Finish

 

RB Rotor Surface Treatment & Finish

EDP coating reaches every internal surface — not just the outside

RB EDP Coating
Uniform coat inside vanes, corners, and crevices
Spray Paint / Plating
Reaches external surfaces only
Full penetration coating — inside the cooling vanes, not just the outside
Reaches what others miss
EDP coating penetrates internal cooling vanes, corners, and crevices with a uniform coat.
Corrosion protection where it counts
Spray painting or plating can only reach external surfaces, leaving internal areas exposed over time.
Cross-cut ground friction surface
The friction surface is finished with cross-cut grinding for consistent pad break-in.
Full engineering detail (coating process, friction surface)

EDP coating process
Rotor hat and disc surfaces are treated and coated by EDP (electro-deposition painting) with black paint, so all the internal cooling vanes, corners, and crevices are penetrated with a uniform coat — unlike spray painting or plating, which can only reach external surfaces.

Friction surface finish
The friction surface receives cross-cut grinding, which supports consistent pad-to-rotor break-in and even initial bite once installed.
