TeraFlex Install: JL/JLU - JK/JKU Delta Brake Kit

teraflex.com/delta-brake-syst...
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)
• 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
• High-Modulus Brake Caliper Kit w/ pads - rear
• 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
• 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 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
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 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). Contact your Mopar dealer for availability.
• JL/JLU_JK/JKU: Delta Brake Kit - Front & Rear - 8x6.5” Bolt Pattern (# 4403480) also available.
Install Time: 4 Hours

I'm very satisfied with my brake kit so far, I will say that when doing a complete install the self bleeding brakes are not very effective, I found that going to the rear right tire and removing the spring and ball made it easy for me to use a suction bleeder and I went ahead and flushed the rest of what was left in my lines I filled and drained the new reservoir 2 times and then the one man bleeding system worked flawlessly. These are well balanced and powerful brakes but retain a factoy smooth feeling. Essentially they are no different than you would expect factory brakes to feel before lifted and such unless you decide to put your foot in them and then they will absolutely put your face in the windshield if you need to stop that quick

Jarrod Ramsey Did you also replace your Master cylinder and brake booster?

[@TriggerHapySheep]

Honestly the 1 person bleed system and ability for quick pad change alone makes this kit worth it lol

[@ixibladeixi2639]

What a nice product. I just wish they designed the fitment without using spacers or wheel upgrade, especially for the 392XR. Might as well get a wheel upgrade and get Baer or Brembo.

[@jeepinjohnny2898]

interesting program however WHY the background racket?

[@RedRockCrawlers]

its soothing. Makes you happy to watch this video. Right?? ;)

[@cathy3845]

should I put grease on the pads like this guy ?

[@teraflexsuspensions]

Try to avoid getting grease on the pads. If you do, wipe it off and blast with some brake clean. Thanks for keeping us on our toes.

[@HR3EEE]

LOlL saw that too

[@nzybailov]

Soft pedal with this calipers, not enough bore on a master cylinder

[@drchow2733]

Installed the delta big brake and booster and mc and having problems ....

[@mylesl2890]

i woulda filed down that cut off edge yikes
