EBC S20K1909 Stage 20 Complete Brake Kit Ultimax Pads and RK Rotors Front and Rear

The EBC S20K1909 is a complete two-axle disc brake kit that pairs EBC's Ultimax2™ brake pads with premium RK series OEM-replacement rotors for both the front and rear axles. Bundling all four corners into a single kit delivers significant savings over purchasing pads and rotors separately, and includes brake caliper lubricant for a thorough, professional-quality service.

Ultimax2™ Brake Pads:

• Constructed with aramid fiber reinforcement for enhanced durability and consistent pedal feel
• Fully shimmed and chamfered to minimize brake noise and vibration
• Features EBC's patented Brake-In™ coating for faster pad seating and optimal performance right after installation
• Engineered for daily-driver use on cars, trucks, and SUVs

RK Series Rotors:

• Direct-fit OEM replacement — no modifications required
• Machined to extremely tight tolerances of less than 0.05mm for precise fitment
• Cast from high-carbon gray iron to reduce brake shudder, heat cracking, and high-frequency vibration
• Geomet anti-rust surface coating protects against corrosion during storage and between uses
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking

Why Renew Front and Rear Together?

Rear brakes contribute up to 40% of a vehicle's total stopping power. Replacing all four corners at the same time ensures balanced, maximum braking performance and eliminates the uneven wear that occurs when only one axle is serviced.

Kit Includes:

• Front brake pads (Ultimax2™)
• Rear brake pads (Ultimax2™)
• Front RK rotors (pair)
• Rear RK rotors (pair)
• Brake caliper lubricant
