TeraFlex 4403450 Delta Brake Kit w/ High Modulus Bridge - 5x5" Bolt Pattern; Wrangler JK, JL, & Gladiator JT

The TeraFlex Delta Brake Kit is the ultimate upgrade for JL/JK Wrangler and JLU/JKU Wrangler Unlimited models requiring increased braking performance such as heavy-laden overland rigs as well as Jeeps with oversized – and heavier – wheels and 33-42” tires. This simple bolt-on upgrade doesn’t require cutting, welding, or adapters. Modulus measures a material’s resistance to elastic (recoverable) deformation under load. A stiff material has a high modulus, which means it only changes shape slightly under high elastic loads before returning to its normal shape. The Delta Brake Kit’s calipers feature a high modulus bridge, which greatly improves stiffness for reduced flex for consistent brake modulation

Specs:

• Minimum Wheel Diameter: 17”

Includes:

• High-Modulus Brake Caliper Kit w/ pads - front
• High-Modulus Brake Caliper Kit w/ pads - rear
• 14” x 1.25” vented rotors - front
• 14” x 1.25” vented rotors - rear
• All necessary hardware

Features & Benefits:

• Significantly improved braking performance over factory brake system
• Balanced front to rear brakes tuned specifically for lifted vehicles
• Brake bias & piston sizes optimized for Wrangler/Unlimited
• Designed to work w/ stock proportioning valve & ABS
• 100% bolt-on upgrade for easy installation

Front & Rear Calipers:

• Opposed 4-piston caliper design w/ 2” pistons
• Same flow rate as factory 2-piston calipers – 4 pistons move each side half the distance instead of 2 pistons only moving one side the full distance
• EPDM synthetic boot material keeps water & other contaminants away from piston
• Hard-chrome coating on piston reduces friction to improve performance
• 4-piece High-Modulus bridge caliper design combines heat-treated 4140 forged steel bridges w/ T6 6061 forged aluminum piston housings
• Steel bridges resist bending/flex better than standard aluminum or cast iron
• Improved stiffness = consistent brake feel/modulation during brake application & release
• Low-profile bridge accepts 14” diameter rotors behind 17” wheels
• 1,000-hour salt spray tested zinc-& E-dipped coating on bridges & mounts
• 300,000 psi steel-formed hardware
• Calipers feature built-in auto bleeding check ball, valve, & spring for easy bleeding
• Hard-coat anodized, scratch-resistant piston bores

Front & Rear Brake Rotors:

• Massive 14” x 1.25” vented rotors for superior stopping performance
• Larger diameter rotors offer more mechanical advantage for more stopping power
• Heat-treated, heavy cast-iron rotors offer better heat absorption
• Mill-balanced, vented rotors for maximum heat dissipation
• Included slotted rotors offer better gas dissipation than smooth rotors
• GEOMET coating on non-friction surfaces resists corrosion

Front & Rear Brake Pads:

• Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub w/ increased pad life & reduce noise & dust
• Drop-in pad design – no need to disassemble calipers to replace pads
