TeraFlex Jeep JK/JL/Gladiator Delta Front Brake Kit 5x5 in. - 4403451

TeraFlex Jeep JK/JL/Gladiator Delta Front Brake Kit 5x5in. - 4403451

The TeraFlex Delta Front 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 inch 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.

Fits:

• JL Wrangler (2 Door)


• JL Wrangler Unlimited (4 Door)


• JK Wrangler (2 Door)


• JT Gladiator (pickup)


• JK Wrangler Unlimited (4 Door)


• Minimum Wheel Diameter: 17 inch


• Back Spacing: 4.75 inch or less


• Bolt Pattern: 5x5 inch

Includes:

• High-Modulus Brake Caliper Kit w/ Pads - Front (part number 4403401)


• 14 inch X 1.25 inch Vented and Slotted Rotors w/ 5x5 inch - Front (part number 4403455)


• All necessary hardware

Features and Benefits:

• Delta Brake System:
  
  
  
  • Significantly improved braking performance over factory brake system
  
  
  • 100 percent bolt-on upgrade w/ basic hand tools
  
  
  • Balanced front to rear brakes tuned specifically for lifted vehicles
  
  
  • Brake bias and piston sizes optimized for JL and JK Wrangler/Unlimited and JT Gladiator models
  
  
  • Designed to work w/ stock proportioning valve and ABS
  
  
  • 3-year warranty
  
  
  
  


• High-Modulus Brake Calipers:
  
  
  
  • Opposed 4-piston caliper design w/ 2 inch front 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 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 inch diameter rotors behind 17 inch wheels
  
  
  • 1,000-hour salt spray tested zinc- and E-dipped coating on bridges and mounts
  
  
  • 300,000 psi steel formed hardware
  
  
  • Calipers feature built-in auto bleeding check ball, valve, and spring for easy bleeding
  
  
  • Hard-coat anodized, scratch-resistant piston bores
  
  
  
  


• Brake Rotors:
  
  
  
  • Massive 14 inch x 1.25 inch 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
  
  
  
  


• Brake 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
  
  
  
  


• Stock Brake Rotor Reference:
  
  
  
  • JL Sahara/Rubicon front: 12.9 inch x 1.1 inch (330mm x 28mm) vented rotors
  
  
  • JL Sahara/Rubicon rear: 13.4 inch x 0.55 inch (342mm x 14mm) solid rotors
  
  
  • JL Sport front: 12.9 inch x 0.94 inch (330mm x 24mm) vented rotors
  
  
  • JL Sport rear: 12.9 inch x 0.47 inch (328mm x 12mm) solid rotors
  
  
  • JK front and rear: 11.9 inch x 1.1 inch (302mm x 28mm) vented rotors (U.S.-spec)
  
  
  
  

Notes:

• Requires a minimum wheel diameter of 17 inch.


• On JK models, we recommend upgrading the stock master cylinder and brake booster to the Mopar Master Cylinder and Brake Booster Kit (part number P5160050). Contact your Mopar dealer for availability.
