Ideal Brake Kit. If you’re looking for a brake kit to improve the braking capabilities of your Sierra, then this Red Wilwood AERO4 Rear Big Brake Kit with Slotted Rotors is perfect for you. Compared to your Sierra’s stock braking system, this rear big brake kit provides a tighter bite with an amazing response time. Ideal for both street and racing applications, this Wilwood AERO4 Rear Big Brake Kit is the perfect solution to all your braking needs.
Effective AERO4 Calipers. Included with this Rear Big Brake Kit are AERO4 4-piston calipers. Each caliper is built with high-quality aluminum alloy billet using a stress-flow forging method to ensure the internal grain structure flows within the contour of these calipers. This forging technique produces better clamping efficiency and superior stopping power that put other brands to shame. Finally, Wilwood completes these calipers with a red powder-coated finish for added style and corrosion-resistance.
GT 72 Curved Vane Slotted Rotors. Wilwood included GT 72 curved vane slotted rotors in this Rear Big Brake Kit. These rotors feature a durable iron alloy construction designed to stand up to the most extreme driving and weather conditions. In addition, these rotors come with asymmetrical slots designed to get rid of dust and gases that can cause brake fade. A black E-coat finish is then applied to keep rust and corrosion from damaging these rotors.
Quality Brake Pads. BP-20 brake pads are included to complement the GT 72 curved vane slotted rotors. Utilizing a high-performance street compound, these brake pads offer a superior bite with a moderate wear rate even under high temperatures. As a result, these brake pads can provide a fast response while minimizing high rotor abrasion and dust production.
No Drilling Needed for Installation. No drilling is needed to install this Wilwood AERO4 Rear Big Brake Kit on your Sierra. Wilwood included all the necessary hardware you’ll need for the installation process.
Contents. This Wilwood AERO4 Rear Big Brake Kit comes with AERO4 4-piston calipers, Smartpad BP-20 brake pads, and GT 72 curved vane slotted rotors.
Brake Line Kit Needed. Your Sierra’s OEM brake lines cannot be used with this Wilwood AERO4 Rear Big Brake Kit’s calipers. For proper installation, a separate brake line kit is needed.
Application. This Red Wilwood AERO4 Rear Big Brake Kit with Slotted Rotors will fit all 1999-2018 GMC Sierra 1500 models.
Application Note. This Wilwood AERO4 Rear Big Brake Kit requires a wheel with a minimum diameter of 18 inches.
