Product Description

The EBC S5KR1728 Rear Stage 5 Brake Kit is engineered to provide improved braking performance and thermal stability for Audi B9-platform applications. Combining EBC Yellowstuff high-friction brake pads with GD Series dimpled and slotted sport rotors, this rear brake package delivers stronger stopping power, improved pedal feel, and enhanced fade resistance during aggressive street driving.

The included GD Series rotors utilize precision-machined slots and dimples to help evacuate brake dust, gases, water, and debris while improving cooling efficiency under repeated braking conditions. Yellowstuff brake pads feature an aramid fiber-based high-friction compound that provides strong initial bite and stable braking characteristics across a broad operating temperature range, making this kit ideal for daily driving, spirited canyon use, and fast-road performance applications.

Designed as a direct-fit rear brake upgrade, the S5KR1728 kit installs using factory mounting points and OE-style dimensions without modification. The Geomet-coated rotors improve corrosion resistance and long-term durability, while EBC's patented brake-in coating promotes faster pad seating after installation. Rear rotor sizing and brake package configuration should always be verified before purchase to ensure exact compatibility.
