EBC S20K1438 Stage 20 Ultimax Brake Pads and RK Rotors Kit - Front and Rear

The EBC S20K1438 Stage 20 Kit is a complete front and rear brake system solution that pairs EBC's Ultimax brake pads with RK series OEM-replacement rotors. Purchasing this two-axle kit delivers significant savings compared to buying each component separately, while ensuring a perfectly matched pad-and-rotor combination for consistent, balanced braking performance.

Ultimax Brake Pads:

• Constructed with Aramid fiber for high efficiency and durability
• Fully shimmed and chamfered for quiet, vibration-free operation
• Features EBC's patented Brake-In coating on the pad surface for faster and safer bed-in immediately after installation
• Eliminates heavy metals and sulfides for an environmentally considerate formulation

RK Series Rotors:

• Direct-fit OEM replacement rotors sized and shaped to factory specifications
• Coated with Geomet anti-rust surface treatment for long-lasting corrosion protection
• Fully balanced and runout-tested to ensure smooth, vibration-free braking
• Machined to tight tolerances for precise fitment

Why Replace Front and Rear Together?

• Maximum braking performance is only achieved when all four corners are working in harmony
• Rear brakes contribute up to 40% of total stopping power and are often overlooked during service
• Renewing both axles simultaneously ensures even wear, balanced stopping distances, and optimal safety

The EBC S20K1438 kit also includes caliper lubricant for a complete, professional-grade installation. Whether performing routine maintenance or upgrading worn components, this kit provides everything needed for a full brake service in one convenient package.
