EBC S20K1539 Stage 20 Ultimax Brake Pad and RK Rotor Kit - Front and Rear

The EBC S20K1539 Stage 20 Kit is a complete two-axle disc brake solution that pairs EBC's Ultimax brake pads with RK series plain rotors for both the front and rear axles — everything needed for a full brake system refresh in a single, cost-effective package. Caliper lubricant is also included.

Ultimax Brake Pads:

• Constructed with aramid fiber reinforcement for consistent, reliable stopping power
• Fully shimmed and chamfered for quiet, vibration-free operation
• Features EBC's patented Brake-In™ coating for accelerated pad bed-in immediately after installation
• Low-dust, street-optimized compound ideal for daily driving

RK Series Brake Rotors:

• Direct OEM replacement fit — no modifications required
• Geomet anti-rust surface coating for long-lasting corrosion protection
• Fully balanced and runout-tested for smooth, judder-free braking
• Machined to tight tolerances for precise, consistent performance

Why Renew Front and Rear Together?

Balanced braking performance depends on all four corners working in sync. Rear brakes contribute up to 40% of total stopping power — replacing both axles at the same time ensures even wear, maximum braking efficiency, and a safer overall system.

The EBC S20K1539 is designed for cars, trucks, and SUVs used in everyday street driving conditions where reliable, fade-free stopping power and long pad life are the priority.
