Description
The TeraFlex JL/JLU_JK/JKU: Delta Brake Kit is the ultimate upgrade for JL/JLU and JK/JKU Wrangler models with over-sized 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.
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. The Delta Brake Calipers features a high-modulus bridge.
Fits:
- JL Wrangler (2-door)
- JLU Wrangler Unlimited (4-door)
- JK Wrangler (2-door)
- JKU Wrangler Unlimited (4-door)
- Minimum Wheel Diameter: 17"
- Back Spacing: 4.5" or less
- MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE
- Bolt Pattern: 5x5"
Includes:
- High-Modulus Brake Caliper Kit w/ pads - front (# 4403401)
- High-Modulus Brake Caliper Kit w/ pads - rear (# 4403402)
- 14" x 1.25" vented & slotted rotors w/ 5x5" bolt pattern - front (# 4403455)
- 14" x 1.25" vented & slotted rotors w/ 5x5" bolt pattern - rear (# 4403456)
- All necessary hardware
Features & Benefits:
- Significantly improved braking performance over factory brake system
- Balanced front to rear brakes tuned specifically for lifted vehicles
- Brake bias & piston sizes optimized for Wrangler
- Designed to work w/ stock proportioning valve & ABS
- 100% bolt-on upgrade for easy installation
Front & Rear Calipers:
- Opposed 4-piston caliper design w/ 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 & 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 forged steel bridges w/ T6 6061 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 & release
- Low-profile bridge accepts 14" diameter rotors behind 17" wheels
- 1,000-hour salt spray tested zinc-& E-dipped coating on bridges & mounts
- 300,000 psi steel formed hardware
- Calipers feature built-in auto bleeding check ball, valve, & spring for easy bleeding
- Hard-coat anodized, scratch-resistant piston bores
Front & Rear Brake Rotors:
- Massive 14" x 1.25" 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 5x5" bolt pattern
Front & Rear Brake Pads:
- Proprietary composite-resin, semi-metallic pads provide excellent full temperature stopping power for maximum initial speed scrub w/ increased pad life & reduce noise & dust
- Drop-in pad design - no need to disassemble calipers to replace pads
