EBC S20K1681 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1681 Stage 20 Brake Kit is a complete two-axle brake refresh that bundles high-performance Ultimax brake pads and direct-fit RK replacement rotors for both the front and rear axles into a single, value-packed package — including caliper lubricant.

Ultimax Brake Pads:

• Built with an aramid fiber compound for low-metallic, low-dust performance
• Fully shimmed and chamfered to minimize brake noise and vibration
• Feature EBC's patented Brake-In™ coating that scours rotor surfaces during initial use, eliminating the need for a lengthy break-in period and promoting even pad-to-rotor mating right away
• Centerline slot design helps prevent heat expansion and brake squeal

RK Series OEM-Replacement Rotors:

• Direct-fit OEM-style replacement — no modifications required
• Geomet anti-rust surface coating protects against road salt and corrosion
• Manufactured from high-quality gray iron with elevated carbon content to resist heat cracking, brake shudder, and high-frequency vibrations
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking
• Vented rotor design promotes airflow between rotor faces to reduce pad fade under load

Why Replace Front and Rear Together?

Maximum braking performance requires all four corners of the braking system to work in unison. Rear brakes contribute up to 40% of total stopping power and are often overlooked during routine maintenance. Replacing front and rear brakes simultaneously with the S20K1681 ensures balanced, predictable stopping and eliminates the uneven wear and brake bias that can result from mismatched component ages.

What's Included:

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