Mercedes Disc Brake Rotor - Zimmermann Formula S 0004212212

Product Information

Sold Individually

Commonly referred to as a Brake Disc or a Brake Rotor, these components play a vital role in your braking system. When applying the brake pedal, this produces hydraulic fluid pressure which then transfers the pressure from the pedal through your braking system and into your brake calipers. The caliper pistons then apply pressure against your brake pads squeezing them inward against your brake rotors ultimately causing friction and stopping the vehicle. Brake rotors are a regular maintenance item which requires either servicing by means of machine work, or most commonly replacement when they become too thin, pulsate, glaze, or grind from worn-out brake pads. It's recommended to replace the brake pads and rotors at the same time.

• Pulsating
• Grinding
• Squeaking
• Glazing
• Hot spots
• A noticeable lip on the rotors outer edge

About Zimmermann Formula S

The key to Otto Zimmermann's success lies in the strategy of being "as close to original equipment as possible," benefiting both the company and its customers. This commitment extends to the recently introduced steel hub brake disc, available to customers since January 2018 and already a standard installation in select Mercedes models. Notably, this compound disc is protected by a patent held by the vehicle manufacturer. In response, Zimmermann has developed a proprietary technique to seamlessly integrate the steel hub with the casted friction ring, presenting an effective solution for the independent aftermarket.

Distinguishing itself, the braking surface on all steel hub-type discs features two sides not connected by ribs but by strategically arranged pillars. At Otto Zimmermann, the design of the ventilation channel adheres to the specifications provided by the vehicle manufacturer. A ventilation channel designed with pillars optimizes airflow, facilitating efficient ventilation and cooling of the brake disc. This is complemented by the use of high-carbon casting material for the friction rings, further enhancing cooling behavior. The casting specification precisely aligns with the vehicle manufacturer's specifications, ensuring a meticulous adherence to quality standards
