Description
The TeraFlex Delta Brake System 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 both front and rear axles.
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)
Specs:
- Minimum Wheel Diameter: 17 inch
- Back Spacing: 4.75 inch or less
- Bolt Pattern: 5x5 inch
- Install Time: 4 Hours

- High-Modulus Brake Caliper Kit with Pads - Front (part number 4403401)
- High-Modulus Brake Caliper Kit with Pads - Rear (part number 4403402)
- 14 inch X 1.25 inch Vented and Slotted Rotors with 5x5 inch - Front (part number 4403455)
- 14 inch X 1.25 inch Vented and Slotted Rotors with 5x5 inch- Rear (part number 4403456)

Delta Brake System Features:
- Significantly improved braking performance over factory brake system
- 100 percent bolt-on upgrade with 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 with stock proportioning valve and ABS
- 3-year warranty
High-Modulus Brake Calipers Features:
- Opposed 4-piston caliper design with 2 inch front pistons and 1.375 inch rear 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 with 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 Features:
- 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 Features:
- Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub with 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

- 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).
