Key Features

Designed to elevate your Jeep Wrangler’s braking system, the Brembo GTS Rear Big Brake Kit offers:

• Enhanced Stopping Power: Larger 380mm diameter rotors paired with 4-piston calipers reduce stopping distances and improve overall brake response.
• Advanced Heat Dissipation: Vented, curved 48-vane rotors with cross-drilled and slotted surfaces minimize heat buildup and brake fade during intense use.
• Superior Build Quality: Monobloc calipers machined from a single billet of cast aluminum provide exceptional rigidity and resistance to deformation.
• Corrosion Resistance: High-carbon alloy rotors feature a corrosion-resistant plating to maintain appearance and performance over time.
• Improved Brake Modulation: Precision-engineered caliper piston design and Brembo’s FM1000 high-performance brake pads deliver consistent pedal feel and control.
• Durable Brake Lines: TUV/DOT homologated stainless steel braided hoses by Goodridge ensure reliable fluid transfer and resistance to expansion.
• Complete Installation Hardware: Includes CNC billet caliper adapters and all necessary fasteners for a seamless upgrade.

Construction & Design

The Brembo GTS Rear Big Brake System features a robust construction centered around monobloc calipers crafted from a single billet of cast aluminum. This design maximizes stiffness and minimizes flex under heavy braking, ensuring consistent pad contact and improved braking precision. The calipers are radial mount style, enhancing rigidity and allowing for better brake pedal feedback.

The 15-inch rotors utilize a two-piece floating design with a floating D-bobbin mounting system and anti-rattle springs, which helps reduce thermal stress and rotor warping. The rotors are made from an advanced high-carbon alloy and finished with a corrosion-resistant plating to extend service life. Their cross-drilled and slotted Type 3 pattern optimizes heat dissipation and helps evacuate brake dust and gases, maintaining clean pad surfaces and consistent braking performance.

Installation & Fitment

This Brembo rear big brake kit is engineered for direct fitment on the rear axle of Jeep Wrangler JK models from 2007 through 2018. The kit comes pre-assembled with all necessary hardware, including Brembo-engineered CNC billet caliper adapters, ensuring a straightforward installation process without the need for vehicle modifications. The included stainless steel braided brake lines are designed for easy connection to existing brake systems, providing enhanced durability and improved brake fluid transfer.
