EBC S20K1039 Stage 20 Ultimax Brake Pads and RK Rotors Kit Front and Rear

The EBC S20K1039 Stage 20 brake kit delivers a complete front and rear brake system upgrade in a single package, pairing EBC Ultimax brake pads with direct-fit RK replacement rotors. Designed for everyday street driving on cars, trucks, and SUVs, this two-axle kit includes everything needed to refresh both axles at once, including caliper lubricant.

EBC Ultimax Brake Pads:

• Aramid fiber-reinforced, low-metallic compound formulated with DuPont Kevlar and Twaron composites
• Reduces rotor wear by up to 50% compared to standard metallic pads
• Fully shimmed and chamfered edges to minimize rotor lip contact and eliminate brake squeal
• Patented EBC Brake-In™ red top coating accelerates pad seating and improves grip during the first 100 miles after installation
• Engineered to match OEM dimensions for proper fit, even wear, and rattle-free performance

EBC RK Series Replacement Rotors:

• Direct-fit OEM replacement geometry for hassle-free installation
• Geomet anti-rust surface coating provides long-lasting corrosion protection
• Fully balanced and runout-tested to ensure smooth, vibration-free braking
• High-carbon gray iron construction reduces brake shudder, heat cracking, and high-frequency vibration

Why Upgrade Both Axles Together?

• Rear brakes contribute up to 40% of total stopping power — often overlooked during routine maintenance
• Replacing front and rear simultaneously ensures balanced, maximum braking performance across all four corners
• Bundled kit pricing provides significant savings over purchasing pads and rotors separately

The S20K1039 kit is engineered for confident daily driving, delivering OEM-quality fit and feel with enhanced durability and reduced noise. A 500-mile break-in period with lighter braking applications is recommended for optimal performance.
