EBC S20K1303 Ultimax Brake Pads & RK Rotors Front and Rear Kit (2-Axle)

The EBC S20K1303 is a complete two-axle disc brake kit that bundles high-performance Ultimax brake pads and RK series rotors for both the front and rear axles, plus caliper lubricant — delivering everything needed for a full brake system refresh in a single package at a significant cost savings over purchasing components separately.

Ultimax Brake Pads:

• Constructed with Aramid fiber for enhanced durability and consistent stopping performance
• Fully shimmed and chamfered to minimize noise and vibration during operation
• Features EBC's patented Brake-In coating (also known as "Brake-In" surface treatment) for faster pad bed-in immediately after installation — no lengthy break-in procedure required
• High-efficiency compound engineered for everyday street driving with improved bite and fade resistance

RK Series Rotors:

• Direct OEM replacement fit — bolt-on installation with no modifications required
• Protected by Geomet anti-corrosion surface coating on non-friction surfaces to resist rust and extend service life
• Fully balanced and runout-tested at the factory to ensure smooth, vibration-free braking

Why Replace Front and Rear Together?

Rear brakes are often overlooked during routine service, yet they contribute up to 40% of a vehicle's total stopping power. Replacing both axles simultaneously ensures balanced braking performance, even pad wear across all four corners, and maximum stopping efficiency. The S20K1303 kit also includes caliper lube to aid proper installation and help prevent brake noise and sticking.

This kit represents a smart, cost-effective solution for a complete brake overhaul, combining OEM-quality fitment with EBC's proven performance upgrades.
