1991 Chevrolet Beretta Brake Rotors and Drums

WBR Run True Technology Metallurgic-Gray (MG) Finished Rotors All World Brake Resources (WBR) brake rotors with Run-True technology are manufactured to match the exact OE fit, OE construction, and precision finishing to ensure quick and easy installation, as well as trouble-free functionality for the life of the rotor. The Metallurgic-Gray coating is applied to all outward non-friction surfaces including in the gap between the plates covering the cooling vanes and cured through an oven drying process. The Gray coating provides an effective anti-rust protection to help maintain a clean appearance. The coating used for WBR is also similar to the OE color used by many OE car makes. WBR Brake Rotors with Run-True Technology have ultra tight tolerances that provide the finest braking experience, from break in throughout the life of the rotor, reducing the chance of warping even under extreme braking temperatures. The coated brake disc provides a protective water based coating that prevents rust and corrosion, extended rotor life and improved visual appearance. WBR Brake Rotors are manufactured to meet or exceed the original equipment manufacturer specification for durability, fit, and function.
