EBC S4KF1239 S4 Brake Kit Redstuff Ceramic Pads and USR Slotted Rotors

The EBC S4KF1239 brake kit combines premium Redstuff ceramic brake pads with USR slotted sport rotors in one complete package, offering excellent value compared to purchasing components separately. This high-efficiency brake kit features aramid fiber pads enhanced with ceramic granules for superior braking power, fully shimmed, slotted and chamfered with EBC's patented Brake-in coating for fast pad seating after installation.

Redstuff Ceramic Brake Pads:

• Premium copper-free ceramic granule-enhanced organic brake pad material designed for fast street driving
• Reduces brake dust by 60-90% compared to conventional pads
• Strong initial bite from cold temperatures that improves as heat increases
• Aramid fiber-based compound enhanced with ceramic particles
• Non-metallic construction with zero steel fiber for minimal rotor wear and easy wheel cleaning
• Fully compliant with ecological standards, containing no toxic ingredients such as lead, nickel, copper, or antimony sulfides
• Nominal friction coefficient of 0.5 with approximately 50% dust reduction
• ECE R90 brake safety tested and approved

USR Slotted Sport Rotors:

• Premium silent street rotors made from high-quality R90-approved G3000 grey iron rotor blanks
• Fine slot pattern designed for improved sport braking with minimal air noise while offering pad degassing and removing dirt, dust, water and debris
• Provides silent braking, cooler brake operation, and guaranteed flat and parallel pad wear
• Finished with thermic black anti-rust coating on non-contact surfaces
• British-made and precision machined in the UK or USA
• Fully balanced and run-out tested for smooth braking performance

The kit includes brake pads, USR rotors, and caliper lube for a complete installation. Being a hard-wearing pad, bed-in times can be as long as 1000 miles and drivers should be patient until the pads take the shape of their rotors. When used together, these matched components deliver superior braking performance for spirited street driving.
