Wilwood 140-18159-D Forged Dynalite Rear Electric Parking Brake Kit 12.19in Rotor 6-Lug SRP

The Wilwood 140-18159-D is a complete bolt-on rear disc brake conversion kit engineered for the 1971–1991 Chevrolet K5 Blazer, K10, GMC K15, and K1500 6-lug 4x4 platforms. Built around Wilwood's FDLI (Forged Dynalite) four-piston caliper platform, this kit integrates a fully electronic parking brake system that eliminates the complexity of traditional mechanical cable setups.

At the heart of the system is Wilwood's Electric Parking Brake (EPB) technology, which delivers secure, high-torque holding power at the push of a button—no mechanical cable connection required. The dedicated ECU communicates with a dash-mounted remote switch and a pre-wired harness assembly, making installation clean and straightforward.

Kit Highlights:

• Forged Dynalite (FDLI) four-piston calipers — lightweight forged billet aluminum construction starting at approximately 3 lbs per caliper
• 12.19-inch x 0.81-inch one-piece SRP rotors — slotted and drilled for improved heat dissipation and bite
• Wilwood BP-10 high-friction street performance brake pads — provide smooth, consistent response with extended wear life
• Electric Parking Brake (EPB) actuator integrated into caliper — no mechanical parking brake cable needed
• Complete EPB control system included — ECU/control unit, dash-mounted switch with indicator light, wiring harness, and all connectors
• Designed for 6-lug axle configurations on 1971–1991 K5 Blazer platform
• Delivers balanced front/rear brake bias for high-performance street and off-road driving

This kit ships complete and ready to install, with everything needed to convert your rear axle to modern disc brakes with an integrated electronic parking brake. It is also compatible with Big Ford 9-inch rear end swap applications. Alternative pad compounds are available separately to suit specific performance or towing demands.
