In the automotive industry, innovation often stems from addressing persistent challenges. Traditional brake rotors have long struggled in corrosive environments, leading to premature failures and safety concerns. PFC Brakes, a leader in braking technology, has introduced a groundbreaking solution: the Zero Failure Isolated ABS Tone Ring. This patented design significantly extends rotor lifespan and ensures reliable performance in even the harshest conditions.
Key Highlights
- Patented design solves corrosion issues in traditional rotors.
- Zero Failure Isolated ABS Tone Ring lasts over five times longer.
- Ideal for medium-duty vehicles like school buses and box trucks.
- Reduces maintenance costs and enhances safety.
Traditional rotors often feature a “cast-in” one-piece design, which, while cost-effective, has a significant drawback. In regions where snow and salt are prevalent, the tone ring—a critical component for the ABS system—can corrode rapidly. This corrosion leads to ABS signal loss, forcing vehicle owners to replace rotors long before the friction surfaces are worn out.
Recognizing this issue, PFC Brakes developed the Zero Failure Isolated ABS Tone Ring. Unlike conventional designs, this tone ring is separate from the rotor casting and is coated with a zinc-nickel plating that resists corrosion. This innovation ensures the tone ring remains functional in aggressive environments, such as those in North America where road salt is heavily used.

To validate their design, PFC subjected their rotors to the rigorous GM9540P corrosion test, which includes high-temperature heat soaks. The results were impressive: PFC’s rotors lasted over five times longer than traditional one-piece designs, proving their superior durability.
This innovation is particularly beneficial for medium-duty vehicles like school buses and box trucks, which often operate in challenging conditions and require reliable braking systems. By extending rotor lifespan and maintaining ABS functionality, PFC’s design reduces maintenance frequency and costs, leading to significant savings for fleet operators. Moreover, it enhances safety by ensuring the ABS system works correctly, even in adverse weather.
PFC Brakes continues to lead the industry with solutions that address real-world challenges. Their isolated ABS tone ring rotors exemplify their commitment to performance, reliability, and safety. For those seeking to upgrade their braking systems, PFC offers a proven solution that withstands the toughest environments.
