TeraFlex 4403450 Delta Complete Brake System Front & Rear 5x5 Kit

The TeraFlex Delta Brake System is a comprehensive performance upgrade designed for Jeep JL Wrangler, JK Wrangler, and JT Gladiator models running oversized tires and heavy-duty applications. This complete front and rear brake system dramatically improves stopping power for vehicles equipped with 33-42 inch tires or heavy overland builds where factory braking performance is insufficient.

High-Modulus Delta Calipers:

The Delta brake calipers feature an advanced high-modulus bridge design that resists flex under extreme braking loads. This rigid construction ensures consistent pad contact and eliminates the caliper deflection that reduces braking efficiency in heavy-duty applications. The result is improved pedal feel, shorter stopping distances, and fade-resistant performance under demanding conditions.

Oversized Slotted and Vented Rotors:

The kit includes 14-inch diameter by 1.25-inch thick vented rotors for both front and rear axles—significantly larger than factory rotors. The slotted design helps evacuate brake dust and gases while maintaining consistent pad bite. The increased rotor mass and venting improve heat dissipation to reduce brake fade during repeated hard stops or mountain descending.

Complete System Includes:

• Front Delta brake caliper kit with high-modulus bridge and brake pads (TeraFlex #4403401)
• Rear Delta brake caliper kit with high-modulus bridge and brake pads (TeraFlex #4403402)
• Front 14-inch x 1.25-inch slotted vented rotors for 5x5-inch bolt pattern (TeraFlex #4403455)
• Rear 14-inch x 1.25-inch slotted vented rotors for 5x5-inch bolt pattern (TeraFlex #4403456)
• All necessary mounting hardware and installation components

Technical Specifications:

• Bolt pattern: 5x5 inch (5x127mm)
• Rotor dimensions: 14 inches diameter x 1.25 inches thick (front and rear)
• Minimum wheel diameter: 17 inches
• Maximum wheel backspacing: 4.75 inches or less
• Rotor design: Slotted and vented for improved cooling

Brake Performance Comparison:

For reference, factory brake rotors on these vehicles range from 11.9 to 13.6 inches in diameter with thickness between 0.47 to 1.1 inches. The Delta system's 14-inch x 1.25-inch rotors provide substantially more braking surface area and thermal mass than any factory configuration, making this upgrade essential for vehicles exceeding factory weight and tire size specifications.

This is a direct bolt-on system requiring no modifications to factory mounting points. Professional installation is recommended to ensure proper bleeding, bedding, and adjustment of the brake system.
