EBC S20K1428 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1428 is a complete two-axle disc brake kit that pairs EBC Ultimax brake pads with EBC RK plain rotors for both the front and rear axles in a single, cost-effective package. Also included is brake caliper lubricant, giving you everything needed for a full brake service in one box.

Ultimax Brake Pads:

• High-efficiency pad compound built with aramid fiber for extended wear life and low dust output
• Fully shimmed and chamfered for quiet, vibration-free braking
• Features EBC's patented Brake-In™ coating for accelerated pad bed-in immediately after installation
• Engineered to exceed OEM pad performance for daily urban driving on sedans, SUVs, and light trucks
• Synthetic aramid fiber and metallic filament blend delivers a long-lasting, high-friction pad

RK Plain Rotors:

• Direct-fit OEM replacement — no modifications required
• Geomet anti-rust surface coating protects against corrosion and extends rotor life
• Fully balanced and runout-tested at the factory for smooth, shudder-free braking
• Premium gray iron construction with higher carbon content reduces heat cracking, brake shudder, and high-frequency squealing vibrations
• Machined to tight tolerances to match original factory dimensions

Why Renew Front and Rear Together?

Rear brakes are often overlooked during routine maintenance, yet they account for up to 40% of a vehicle's total stopping power. Replacing pads and rotors on both axles simultaneously ensures balanced, maximum braking performance and helps prevent uneven wear.

Kit Includes:

• Front Ultimax brake pads
• Rear Ultimax brake pads
• Front RK plain rotors
• Rear RK plain rotors
• Brake caliper lubricant
