Wilwood 140-18157-D Aero6 Front Brake Kit for 1971-1991 Blazer, 15.00" Rotor, 6-Lug, SRP

The Wilwood Aero6 Front Big Brake Kit (140-18157-D) is engineered for heavy-duty stopping power on full-size trucks and SUVs. Designed specifically for 1971–1991 Chevy/GMC Blazer applications with 6-lug hubs, this kit delivers serious braking performance for towing, off-road use, and builds featuring upgraded wheels and tires.

At the heart of this kit is the Aero6 six-piston caliper — Wilwood's largest street/truck caliper — paired with a massive 15.00-inch directional staggered-vane rotor finished in Wilwood's Silver Zinc dichromate coating (SRP). The directional vane rotor geometry promotes maximum airflow through the rotor for superior heat dissipation, ensuring consistent fade-free performance under sustained heavy braking.

Key Features:

• Aero6 six-piston billet aluminum calipers for maximum clamping force
• 15.00-inch directional staggered-vane rotor for maximum cooling and durability
• Silver zinc dichromate (SRP) rotor finish for corrosion resistance
• 6-lug hub compatibility for 1971–1991 Blazer applications
• Fully compatible with OE master cylinder output and factory ABS function
• Designed for towing, off-road, and extreme-duty street use
• Complete bolt-on kit with all necessary hardware included

Kits listed for specific vehicles are fully engineered to be compatible with the OE master cylinder, ensuring proper pedal feel and brake bias right out of the box. Whether you're building a show truck, a trail rig, or a heavy hauler, the Wilwood 140-18157-D provides the big brake performance your build demands.
