EBC S20K1137 S20 Ultimax Brake Pad and RK Rotor Kit Front and Rear 2-Axle

The EBC S20K1137 is a complete two-axle brake service kit that bundles Ultimax brake pads and RK replacement rotors for both front and rear axles, plus caliper lubricant — everything needed for a full brake renewal in one package.

The Ultimax pads are engineered with aramid fiber construction and feature full shimming and chamfering for quiet, vibration-free operation. EBC's patented Brake-in™ coating accelerates pad seating after installation, so brakes reach full performance faster without the need for an extended break-in process.

The RK rotors are a direct-fit OEM replacement designed to bolt on without modification. Each rotor features a Geomet anti-corrosion surface coating and is fully balanced and runout-tested at the factory, ensuring smooth, vibration-free braking from day one.

Why Replace Front and Rear Together?

Rear brakes contribute up to 40% of a vehicle's total stopping power — yet they're often overlooked during service. Renewing both axles simultaneously restores balanced braking performance across the entire system, maximizing safety and efficiency.
