Check out the Northridge Nation Article: TeraFlex Delta Brake Kit for Jeep JL & JK
Check out this video: Testing Teraflex Delta Brakes
The TeraFlex Delta Brake Kit is the ultimate upgrade for JT/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: 4.75” or less
– MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE
• Bolt Pattern: 5x5”
Note: Will not work with Hutchinson's Rock Monster wheels.
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/ 5x5” bolt pattern - front (# 4403455)
• 14” x 1.25” vented & slotted rotors w/ 5x5” bolt pattern - rear (# 4403456)
• 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 5x5” 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
Stock Brake Rotor Reference:
JL/JLU Sport front: 12.9” x 0.94” (330mm x 24mm) vented rotors
JL/JLU Sport rear: 12.9” x 0.47” (328mm x 12mm) solid rotors
JL/JLU Sahara/Rubicon front: 12.9” x 1.1” (330mm x 28mm) vented rotors
JL/JLU Sahara/Rubicon rear: 13.4” x 0.55” (342mm x 14mm) solid rotors
JK/JKU front: 11.9” x 1.1” (302mm x 28mm) vented rotors (U.S.-spec)
JK/JKU rear: 11.9” x 1.1” (302mm x 28mm) vented rotors (U.S.-spec)
Note(s):
• Requires a minimum wheel diameter of 17”.
• On JK/JKU models, we recommend upgrading the stock master cylinder and brake booster to the Mopar Master Cylinder & Brake Booster Kit (# P5160050). Click here.
• JL/JLU_JK/JKU: Delta Brake Kit - Front & Rear - 8x6.5” Bolt Pattern (# 4403480) also available.
A: They should work, but I would recommend downloading the template and using it to determine if you have proper clearance.
Northridge Kaleb @ Northridge4x4 4 years agoA: Teraflex has recently updated their description to say that they work with 4.75" of backspacing or less. They do also provide this template so that you can check to be sure they'll fit with your wheels. https://teraflex.com/file/attachments/5c7e2638d883ac0079b8ae86.pdf
