Now that you’ve upgraded the tires on your Wrangler or Gladiator to give you the off-road performance and style you’re looking for, it’s time to ensure you’ve got the stopping power and reliability you need to stay safe on the road or the trail. With this TeraFlex (4403480) Delta Big Brake Kit with a 8" x 6-1/2" Bolt Pattern you can rest assured that your rugged rig will stop when and where you want it to.

Features and Benefits:
- For 8”x6-1/2” bolt patterns
- Significantly improved braking performance over factory brake system
- Balanced front to rear brakes tuned specifically for lifted vehicles
- Brake bias and piston sizes optimized for Wrangler
- Designed to work with stock proportioning valve & ABS
- 100% bolt-on upgrade for easy installation
- 3-year warranty

Specifically designed and developed to work with your oversized and heavier wheel and tire combos requiring increased braking performance, this kit is a must for 33”-42” tires or heavy-laden overland rigs. Additionally, it includes all the components required to upgrade both your front and rear axles. Lastly, the included brake calipers feature a high-modulus bridge.

This Kit Includes:
- High-Modulus Brake Caliper Kit with pads- front
- High-Modulus Brake Caliper Kit with pads – rear
- 14” x 1.25” vented and slotted rotors with 8x6.5” bolt pattern - front (P/N: 4403485)
- 14” x 1.25” vented and slotted rotors with 8x6.5” bolt pattern - rear (P/N: 4403486)
- All necessary hardware

Front and Rear Calipers:
- Opposed 4-piston caliper design with 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 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 bridge with T6 6061 forged aluminum piston housings
- Steel bridges resist bending and flex better than standard aluminum or cast iron
- Improved stiffness yields 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
- 300,000PSI steel formed hardware
- Calipers feature built-in auto bleeding check ball, valve and spring for easy bleeding
- Hard-coat anodized, scratch-resistant piston bores

Front and Rear Brake Rotors:
- Massive 14” x 1-1/4” 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 8” x 6-1/2” bolt pattern

Front and Rear Brake Pads:
- Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub with increased pad life and reduce noise and dust
- Drop-in pad design
- No need to disassemble calipers to replace pads
