Jeep JK/JL/Gladiator Delta Front Brake Kit 8×6.5 Inch For 07-Pres Wrangler JK JL/20-Pres Gladiator TeraFlex

1 784.00

En stock


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.

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)


  • 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.
