Parking Brake Hat - Truck - Product Description

These premium grade cast iron hats make it possible to use bolt-on rotors on vehicles equipped with OEM internal shoe parking brake assemblies. Each hat is a precision machined, threaded hole design for use in conjunction with through-hole mount rotors. After machining, the hats are electro-coated for corrosion resistance. Used for big rotor brake kits on truck, SUV, and 4WD axles with either 6 or 8 lug configurations.


Truck Hats feature strengthening ribs on a flared bell configuration for big rotor brake kits on truck, SUV, and 4WD axles with either 6 or 8 lug configurations.

GT 72 Curved Vane Rotor Rotors

Wilwood's GT & GTB 72 Curved Vane Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Combined with our proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest braking available. GTB rotor have additional black e-coat finish applied for applications where corrosion resistance is concern. View GT Rotors

SRP Drilled Performance Rotor Rotors

SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight. View SRP Rotors
