Features & Product Details

Check out the Northridge Nation Article: TeraFlex Delta Brake Kit for Jeep JL & JK

Check out this video: Testing Teraflex Delta Brakes

The TeraFlex Delta Brake Kit is the ultimate upgrade for JT/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.

Minimum Wheel Diameter: 17”

Back Spacing: 4.75” or less

– MUST VERIFY FITMENT W/ DOWNLOADABLE TEMPLATE

Bolt Pattern: 5x5”

Note: Will not work with Hutchinson's Rock Monster wheels.

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

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

Worth the money 1 year ago

Installed on a stock 2024 JL Rubicon. The installation is straightforward and easy. The only minor issue I had was on the rear. The instructions have you bend the brake line outward prior to removing the stock caliper, which I did. Unfortunately, I didn't bend it far enough and the banjo fitting wouldn't attach to the Teraflex caliper. I was unable to bend it and had to remove the Teraflex caliper and rotor in order to reattach the stock parts, where I was able to get the tube bent correctly. The other end of the rear axle went smoothly. After bleeding, I performed a brake bedding series of stops and then re-bled the brakes. The Teraflex has a very noticeable improvement in clamping pressure and brake pedal feel. The brake pedal is not much firmer or "grabbier" than stock at the beginning, but after ¼ of downward travel, the brakes really begin to clamp and are much more effective than the stock system. I have put about 700 miles on the new brakes and they are still quiet.

Big Improvement! 2 years ago

5out of 5stars

Replaced the brakes on my 2018 JLUR because the factory brakes were really starting to annoy me with their lack of power. Yes, it’s lifted and yes it’s on 35’s but I expected more I guess. Easy installation. Hardest part was getting the old discs off. Put braided lines on while I had everything apart. Not super keen on the speed bleeders but they work ok. Overall a BIG improvement over my stock system.

Delta brake kit install. 4 years ago

4out of 5stars

JKJV
I installed this brake kit on my jk. Pretty straight forward install as calipers and rotors go. With the install J8 booster and steel braided lines were also done. Braking has been tremendously improved, the only issue is after a short while brake squeal can be heard a lot of the time. The brake pads are modeled after the 14-21 Tundra brake pads so squealing is normal for them. When maintenanced the pads are interchangeable with tundra pads but the rotors are special machined by Teraflex so will have to be source from them.

Teraflex BBKs are worthless. Read this before you buy 5 years ago

2out of 5stars

Projkt07
Specific Post about Big Brake Kits. Bit of a long term review. JK still streetable, but treated more as a dedicated wheeler last 2-3 years. Owned both the larger rotor/stock caliper, and the delta. Bought the BBK in 2015. Deltas in 2019. Waste of money. The stock upgrade bbk has a bad casting design specifically in the rear where it ejects pad clips so the pad is able to free float in the bracket and prematurely wear out. Went through a set of wagners in 8k and Ebcs in 5k with new rear rotors and teraflex sending me a new bracket... same. Worse actually. All 4 came out instead of 1 or 2. I have pictures. The Delta I saw as the solution. With other kits 3K+ for all 4 corners, the price point was attractive, but still not cheap at just over 2. The things you dont realize until you have them in your hand, single side bleeder over one on each side like a baer wilwood or brembo. Bleeder is up highest point but sticks out so it could get caught while wheeling (hasnt luckily) and the banjo is all the way at the lowest point where it can get caught on passing rocks. My pass rear has turned the banjo left twice (on the driver it would tighten it if that happened). You know when you loose pedal. Its fun... lol. I keep a 15mm in my console and a spare banjo and brake lines and brake fluid in my kit because you never know... It didnt give me anymore braking performance over the stock upgrade is the worst part. So I added the JK8 booster... Still not much better. Better than stock. Also requires 30in lines on 11in shocks... The stock banjo is center of caliper... so is a brembo btw... nickel and dime after you get them. So Ive had the Deltas for a year and a half. 3500 miles. Not a daily driver. Rock wheeling and trailered. Pads on all four corners are gone. So I bought some hawks. Taking the pads off? The pistons are regular steel. Not stainless, not aluminum, not composite. Pitting rust. There are 16 of them. All of them. Teraflexes solution? I should wash my Jeep, lol. Mine is wheeled, washed, garaged. Never snow/salt. When you have to switch out brake pads every year, it doesnt really matter does it? Itd be nice if the rest of it were made with quality components to save the half baked design, but both suffer. Save your money if you want a big brake kit. Long term, youll spend more money with Teraflex. Wilwood, Brembo, Baer. All cheaper long term and far less maintenance and stops better (Have brembos on my Durango RT... smooth control... 15K since install and pad is still 80/90%). I should have learned after the first kit... Read this and buy something else. 2 out of 5 stars.

Q: Tera flex delta brakes Moya6 years ago
Will my 17” rim with 4.75 back space rim work with the Tera Flex Delta brakes fit?
- 0 of 0 people found the following answer helpful
  A: Teraflex has recently updated their description to say that they work with 4.75" of backspacing or less. They do also provide this template so that you can check to be sure they'll fit with your wheels. https://teraflex.com/file/attachments/5c7e2638d883ac0079b8ae86.pdf
