Product Details

The EBC S20K1223 Stage 20 Brake Kit is a complete front and rear disc brake solution, pairing EBC's high-efficiency Ultimax brake pads with precision RK Series plain rotors for a balanced, full-axle brake renewal in a single kit. Includes caliper lubricant for a complete installation.

Ultimax Brake Pad Features:

  • Constructed with aramid fiber for enhanced durability and consistent braking performance
  • Fully shimmed and chamfered to reduce noise and vibration
  • Patented EBC Brake-In™ coating pre-applied for faster, safer pad bedding after installation
  • Centerline slot design helps prevent heat expansion and brake noise

RK Series Rotor Features:

  • Direct-fit OEM replacement geometry — no modifications required
  • Geomet anti-rust surface coating provides long-lasting corrosion protection
  • Fully balanced and runout tested for smooth, vibration-free braking

Why Replace Front and Rear Together?

Maximum braking performance depends on all four corners working in unison. The rear brakes contribute up to 40% of total stopping power — replacing all axles at the same time ensures balanced, predictable braking and avoids uneven wear. This two-axle kit delivers everything needed for a complete brake service.

Kit Includes:

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