EBC Rear Brake Pad and Rotor Kit for 2020+ Audi A4 B9 2.0T
The EBC kit delivers reliable braking for drivers of premium imports who demand consistent performance at any speed with reduced dust buildup. This rear-specific assembly combines Yellowstuff brake pads and USR slotted rotors for direct replacement on stock setups, ensuring smooth operation without modifications. Built for spirited driving in modified or daily-driven vehicles, the kit provides effective stopping power through aramid fiber construction enhanced by ceramic granules in the pads, paired with slotted rotors that promote even wear and heat dissipation. Every component undergoes balancing and runout testing for vibration-free braking, backed by a 10,000-mile warranty.
