The Wilwood Dynamic Park Brake hat uses the bobbin-style mounting system to allow rotor movement independent of the hat, eliminating thermally generated stress at the attachment points. That results in flatter, truer rotors with consistent brake response and pedal feel while preventing pad knock-back and rotor drag. It is machined for use with internal parking brake configurations requiring dynamic rotor mounting.
