EBC S20K1391 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1391 is a complete two-axle disc brake kit that pairs EBC's high-efficiency Ultimax brake pads with precision-matched RK plain rotors for both the front and rear axles in a single purchase. Renewing all four corners at once ensures balanced, consistent stopping performance — rear brakes contribute up to 40% of total stopping power and are often overlooked during routine maintenance.

Ultimax Brake Pad Features:

• Constructed with aramid fiber for high efficiency and low dust
• Fully shimmed and chamfered to minimize noise and vibration
• Treated with EBC's patented Brake-In™ coating for accelerated pad bed-in right out of the box
• Compatible with ABS and electronic brake distribution systems

RK Rotor Features:

• Direct-fit OEM replacement — no modifications required
• Geomet anti-rust surface coating protects against road salts, brine, and corrosion
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking
• Vented rotor design promotes heat dissipation and reduces brake fade
• Manufactured from high-carbon grey iron for long-lasting durability

Kit Includes:

• Front brake pads (both sides)
• Rear brake pads (both sides)
• Front RK rotors (pair)
• Rear RK rotors (pair)
• Caliper lubricant
