EBC S20K1628 Stage 20 Ultimax Brake Pad & RK Rotor Kit Front and Rear

The EBC S20K1628 is a complete Stage 20 two-axle brake kit that bundles Ultimax brake pads and RK series rotors for both the front and rear axles in a single, value-packed package — delivering a significant cost savings over purchasing components separately. The kit also includes caliper lube for a thorough, professional-quality brake service.

Ultimax Brake Pads

EBC's Ultimax pads are engineered with aramid fiber reinforcement and are fully shimmed and chamfered to minimize brake noise and vibration. Each pad features EBC's patented Brake-In™ coating, which conditions the rotor surface on first use to dramatically reduce the break-in period and deliver confident stopping power right out of the box.

RK Series Rotors

The included RK rotors are precision-engineered as a direct-fit OEM replacement, machined to tight tolerances and balanced to eliminate vibration and pedal pulsation. Each rotor is treated with a Geomet anti-rust surface coating that protects against corrosion from road salts, brine, and moisture. Every rotor is fully balanced and runout-tested before leaving the factory to ensure smooth, consistent braking.

Why Replace Front and Rear Together?

Maximum braking performance requires all four corners working in unison. Rear brakes contribute up to 40% of your vehicle's total stopping power — yet they are often overlooked during routine maintenance. Renewing both axles at the same time restores balanced, predictable braking and ensures even wear across all components.

Kit Includes:

• Front Ultimax brake pads (aramid fiber, shimmed, chamfered, Brake-In coated)
• Rear Ultimax brake pads (aramid fiber, shimmed, chamfered, Brake-In coated)
