EBC S20K1839 S20 Ultimax Brake Pad & RK Rotor Kit Front and Rear

The EBC S20K1839 is a complete two-axle brake kit that bundles high-performance Ultimax brake pads and RK geomet-coated rotors for both the front and rear axles, plus caliper lubricant — delivering everything needed for a full brake system refresh in a single, cost-effective package.

Key Features:

• Complete 2-Axle Kit: Includes pads, rotors, and caliper lube for both front and rear axles — no separate purchases required
• Ultimax Brake Pads: Constructed with Aramid fiber reinforcement for quiet, dust-reduced, high-efficiency braking in everyday street driving conditions
• EBC Brake-In Coating: Patented coating applied at the factory accelerates the pad bed-in process immediately after installation, reducing the break-in period significantly
• Fully Shimmed and Chamfered Pads: Precision-machined edges and integrated shims minimize noise and vibration for a smooth, quiet braking feel
• RK Geomet-Coated Rotors: OEM direct-fit replacement rotors feature a Geomet anti-corrosion surface coating that protects against rust and oxidation without affecting braking performance
• Balanced and Runout Tested: Every rotor is precision-balanced and runout-tested at the factory to ensure vibration-free, smooth stopping power
• Rear Brake Performance: Rear brakes contribute up to 40% of total stopping power — renewing front and rear simultaneously ensures balanced, maximum braking efficiency
• Caliper Lubricant Included: Supplied caliper lube supports proper caliper operation and longevity during and after installation

Replacing front and rear brakes at the same time restores full, balanced stopping power to the entire brake system. The EBC S20K1839 kit simplifies the job by delivering every component in one box, making it an ideal choice for DIY installers and professional shops looking for a reliable, factory-tested brake solution.
