The Wilwood 140-18152-DR is a Forged Narrow Superlite 4R (FNSL4R) Rear Electronic Parking Brake Big Brake Kit engineered for Big Ford New Style axle housings with a 2.50" offset and 6-lug bolt pattern. Designed for custom builds, high-performance street machines, and show cars that demand serious stopping power with a clean, cable-free parking brake solution.
At the heart of this kit are Wilwood's FNSL4R four-piston forged calipers finished in red powder coat, paired with a 12.88" two-piece SRP (Slotted & Drilled) rotor for superior heat dissipation and fade resistance. BP-10 high-performance brake pads deliver optimized, balanced braking force that complements front big brake upgrades across a wide range of performance applications.
The integrated Electronic Parking Brake (EPB) caliper eliminates traditional mechanical cables entirely, providing high-torque static holding power for reliable parking engagement. The kit includes a control unit and harness assembly, streamlining installation and everyday use without the complexity of a conventional cable-actuated system.
