EBC S20K1515 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1515 Stage 20 Brake Kit is a complete front and rear disc brake solution, delivering factory-fit performance with premium materials. This two-axle kit bundles EBC Ultimax brake pads and RK plain rotors — along with caliper lubricant — in a single package, covering everything needed to refresh both axles at once.

EBC Ultimax Brake Pads:

• Constructed with Aramid fiber for high-efficiency friction and long pad life
• Fully shimmed and chamfered to reduce noise and vibration
• Factory-applied EBC Brake-In coating accelerates pad bedding after installation, reducing the break-in period
• FMSI Pad Numbers: UD696 (Front) / UD340 (Rear)

EBC RK Series Rotors:

• Direct OEM-replacement fit — no modifications required
• Geomet anti-rust surface coating provides long-lasting corrosion protection
• Fully balanced and runout-tested at the factory for vibration-free, smooth braking
• Front rotor: 280mm vented, 5-bolt, 65mm center bore (RK578)
• Rear rotor: 226mm solid, 5-bolt, 57mm center bore (RK577)

Why Replace Front and Rear Together?

Maximum braking efficiency is only achieved when all four corners are performing equally. The rear brakes contribute up to 40% of a vehicle's total stopping power, yet they are often overlooked during routine maintenance. Replacing the front and rear simultaneously ensures balanced, predictable stopping performance and eliminates uneven wear.

Kit Contents:

• Front brake pads — UD696
• Rear brake pads — UD340
• Front rotors (pair) — RK578
• Rear rotors (pair) — RK577
• Caliper lubricant

Manufactured in Great Britain, the EBC S20K1515 is a straightforward, high-quality upgrade over worn OEM components for everyday street driving.
