EBC S20K1052 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1052 Stage 20 Brake Kit is a complete two-axle brake refresh that pairs EBC's Ultimax brake pads with direct-fit RK plain rotors for both the front and rear axles — everything needed for a full brake system renewal in a single purchase.

Ultimax Brake Pads:

• Engineered with aramid fiber construction for consistent stopping power and long pad life
• Fully shimmed and chamfered to reduce brake noise and vibration
• Features EBC's patented Brake-In™ coating that conditions the rotor surface and accelerates pad bed-in from the very first stop

RK Series Replacement Rotors:

• Direct-fit OEM replacement design — no modifications required for installation
• Finished with a Geomet anti-rust surface coating to resist corrosion from road salts and brine
• Fully balanced and runout-tested at the factory for vibration-free, smooth braking performance
• Machined to tight tolerances using high-quality gray iron that meets or exceeds OEM thermal and wear specifications

Why Replace Front and Rear Together?

• Rear brakes contribute up to 40% of total vehicle stopping power — often overlooked during routine maintenance
• Replacing all four corners at once ensures balanced, predictable braking across the entire vehicle
• Bundling both axles into a single kit offers significant savings over purchasing pads and rotors individually

The S20K1052 kit also includes caliper lubricant to ensure proper caliper function during installation. This kit is the ideal choice for drivers seeking a reliable, OEM-quality brake upgrade for everyday street driving.
