Delta Brake System w/ High Modulus Bridge

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” 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.

FEATURES/BENEFITS

Delta Brake System:

  • Significantly improved braking performance over factory brake system
  • 100% 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 calipers w/ 2” front pistons and 1.375” 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 the 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” diameter rotors behind 17” 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” x 1.25” vented rotors for superior stopping performance
  • Larger diameter rotors offer more mechanical advantages 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
