Wilwood 140-18162-DR AERO4 Rear Disc/Drum Big Brake Kit 14.00" Rotor 6-Lug Red

The Wilwood 140-18162-DR is a rear disc/drum big brake conversion kit designed for demanding performance and custom vehicle applications. Featuring Wilwood's radial-mount AERO4 four-piston caliper in a bold red powder coat finish, this kit replaces the factory rear disc brakes while retaining the OE drum parking brake assembly for a clean, functional integration.

At the heart of this kit is an oversized 14.00-inch SRP (Slotted, Rust Preventative) drilled and slotted rotor designed to maximize thermal dissipation, extend pad life, and deliver consistent stopping power under hard use. The 6-lug configuration ensures a direct, secure fitment on the target application.

Key Features:

• AERO4 radial-mount calipers with four-piston design for even pad wear and high clamping force
• 14.00" slotted and drilled SRP rotors for superior heat management and bite
• High-friction BP (Street Performance) compound brake pads included
• Red powder coat caliper finish for a premium appearance
• 6-lug bolt pattern for correct axle fitment
• Retains OE drum parking brake assembly — no parking brake modification required
• Matched to OE master cylinder output and ABS system compatibility
• Ideal complement to front big brake upgrades for balanced bias

This kit is engineered to work in harmony with the factory master cylinder output and individual vehicle brake bias requirements, making it a straightforward upgrade path for custom builds, restorations, and performance street applications. The disc/drum design preserves the original parking brake function while dramatically upgrading overall braking performance.
