EBC S20K1863 Ultimax Brake Pad and RK Rotor Kit Front and Rear 2-Axle

The EBC S20K1863 is a complete two-axle brake service kit, pairing Ultimax high-efficiency brake pads with RK series OEM-replacement rotors for both the front and rear axles. The kit also includes caliper lubricant, making it a comprehensive, all-in-one solution for a full brake service.

Ultimax Brake Pads:

• Constructed with aramid fiber for high strength and durability
• Fully shimmed and chamfered to reduce brake noise and vibration
• Features EBC's patented Brake-in™ coating for faster pad seating after installation — no lengthy break-in procedure required
• Engineered for everyday street driving with superior stopping power and low dust output

RK Series Rotors:

• Direct-fit OEM replacement — no modifications needed for installation
• Finished with a Geomet anti-rust surface coating to resist corrosion from road salts and moisture
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking
• Vented rotor design promotes heat dissipation and reduces pad fade

Why Replace Both Axles at Once?

Balanced braking performance depends on all four corners working together. The rear brakes contribute up to 40% of total stopping power, yet are often overlooked during routine maintenance. Replacing front and rear brake components simultaneously ensures even wear, consistent pedal feel, and maximum braking efficiency.

What's Included:

• Front brake pads (Ultimax)
• Rear brake pads (Ultimax)
• Front rotors (RK series)
• Rear rotors (RK series)
• Caliper lubricant
