Delta Front and Rear Brake Kit 5×5″ Bolt Pattern for 2007-2025 Wrangler JK/JL and 2020-2025 Gladiator JT
Description:
The TeraFlex JL/JLU–JK/JKU: Delta Brake Kit is the ultimate upgrade for JL/JLU and JK/JKU Wrangler 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. 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)
JT Gladiator

High-Modulus Brake Caliper Kit w/ pads- front
High-Modulus Brake Caliper Kit w/ pads – rear
14″ x 1.25″ vented & slotted rotors w/ 5×5″ bolt pattern – front (# 4403455)
14″ x 1.25″ vented & slotted rotors w/ 5×5″ 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
3-year warranty
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 cast steel bridge 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 5×5″ 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
Stock Brake Rotor Reference: JL/JLU Sport front: 12.9″ x 0.94″ (330mm x 24mm) vented rotors JL/JLU Sport rear: 12.9″ x 0.47″ (328mm x 12mm) solid rotors JL/JLU Sahara/Rubicon front: 12.9″ x 1.1″ (330mm x 28mm) vented rotors JL/JLU Sahara/Rubicon rear: 13.4″ x 0.55″ (342mm x 14mm) solid rotors JK/JKU front: 11.9″ x 1.1″ (302mm x 28mm) vented rotors (U.S.-spec) JK/JKU rear: 11.9″ x 1.1″ (302mm x 28mm) vented rotors (U.S.-spec)
Note(s):
Requires a minimum wheel diameter of 17″.
On JK/JKU models, we recommend upgrading the stock master cylinder and brake booster to the Mopar Master Cylinder & Brake Booster Kit (# P5160050).
