Product Details

The EBC S20K1233 Stage 20 Brake Kit is a complete two-axle disc brake solution, pairing EBC's proven Ultimax2 brake pads with RK Series plain rotors for both the front and rear axles. Buying as a kit delivers real savings over purchasing pads and rotors separately, and every kit includes caliper lubricant for a complete, professional installation.

Ultimax2 Brake Pads:

  • Constructed with aramid fiber for high efficiency and durability
  • Fully shimmed and chamfered to minimize brake noise and vibration
  • Coated with EBC's patented Brake-In™ coating for faster pad seating right after installation—no lengthy bed-in required
  • Centerline slot design helps prevent heat expansion and reduces noise during braking

RK Series Rotors:

  • Direct-fit OEM replacement — no modifications required
  • Geomet anti-rust surface coating protects against road salt, brine, and corrosion
  • Fully balanced and runout-tested at the factory for smooth, vibration-free braking
  • Cast from high-quality gray iron that meets or exceeds OEM thermal and wear specifications

Why Replace Front and Rear Together?

Balanced braking performance depends on all four corners working in sync. Rear brakes contribute up to 40% of total stopping power — often overlooked during routine maintenance. Renewing both axles at the same time with the S20K1233 ensures consistent pedal feel, even pad wear, and maximum braking efficiency from the first stop.

Kit Includes:

  • Front and rear Ultimax2 brake pads
  • Front and rear RK Series plain rotors
  • Caliper lubricant

Good product, great price, will do business again.

Great price on parts, shipping a tad high but still okay

SO far, so good. We ordered a new Weathertech Trunk Liner from Autoplicity for our new VW SportWagen. We were pleased to find exactly what we were looking for for $50 less than other locations.

Good price & easy check out
