TeraFlex Delta Brake System - 8x6.5" for Jeep JK / JKU, JL / JLU, JT Gladiator

The TeraFlex Front Delta Brake Kit is the ultimate upgrade for JL and JK Wrangler/Unlimited and JT Gladiator models with oversized and heavier wheels/tire combos requiring increased braking performance. A must for 33-42" tires or heavy-laden overland rigs. Includes all the components required to upgrade the front axle.

Delta Brake Calipers feature a high-modulus bridge. 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.

Features:

• Significantly improved braking performance over factory brake system
• 100% bolt-on upgrade w/ basic hand tools
• Balanced front to rear brakes tuned specifically for lifted vehicles
• Brake bias and piston sizes optimized for all JL, JK, and JT models
• Designed to work w/ stock proportioning valve and ABS
• 3-year warranty Calipers:
• Opposed 4-piston calipers w/ 2'' front pistons
• Same flow rate as factory 2-piston calipers ''" 4 pistons move each side half the distance instead of 2 pistons only moving 1 side the full distance
• EPDM synthetic boot material keeps water and 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 cast steel bridges w/ 6061-T6 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 and release
• Low-profile bridge accepts 14'' diameter rotors behind 17'' wheels
• 1,000-hour salt spray tested zinc
• and E-dipped coating on bridges and mounts
• 300,000 psi steel formed hardware
• Built-in auto bleeding check ball, valve, and spring for easy bleeding
• Hard-coat anodized, scratch-resistant piston bores Rotors:
• Massive 14'' x 1.25'' vented rotors offer more mechanical advantage for superior stopping performance
• Heat-treated, heavy cast-iron rotors offer better heat absorption
• Mill-balanced, slotted and vented rotors offer maximum gas and heat dissipation, respectively, compared to solid rotors
• GEOMET coating on non-friction surfaces resists corrosion Pads:
• Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub w/ increased pad life and reduced noise and dust
• Drop-in pad design ''" no need to disassemble calipers to replace pads
