Teraflex Delta Brake System with Mopar Master Cylinder and Vacuum Brake Booster Kit

Description

Type a description for this product here…

The TeraFlex Delta Brake Kit is the ultimate upgrade for JL/JLU and JK/JKU Wrangler 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 both front and rear axles.

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 Calipers features a high-modulus bridge.

• Minimum Wheel Diameter: 17” 
• Back Spacing: 4.5” or less 
– MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE 
• Bolt Pattern: 8×6.5”

Includes:

• High-Modulus Brake Caliper Kit w/ pads- front (# 4403401) 
• High-Modulus Brake Caliper Kit w/ pads – rear (# 4403402) 
• 14” x 1.25” vented & slotted rotors w/ 8×6.5” bolt pattern – front (# 4403485)
• 14” x 1.25” vented & slotted rotors w/ 8×6.5” bolt pattern – rear (# 4403486) 
• 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 
• 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 
• Rotors feature 8×6.5” bolt pattern

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
