## Overview

The TeraFlex Delta Brake Kit is a premium, vehicle-specific upgrade for Jeep Wrangler JK and JL models, engineered to handle oversized tires (33-42") and heavy loads. Featuring massive 14" vented and slotted rotors paired with high-modulus 4-piston calipers, this 100% bolt-on kit delivers superior stopping power, heat dissipation, and durability. Designed for easy installation and optimized brake bias, it’s the ultimate brake upgrade for lifted Wranglers demanding reliable, high-performance braking.

## Description

The TeraFlex JL/JLU–JK/JKU: Delta Brake System 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. Delta Brake Calipers feature a high-modulus bridge. 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.

Review: Great brakes - I’m super happy with these brakes on my 2014 2 door Rubicon with a 3.5” lift and 37”tires. A few years ago I did the PowerStop brakes (replacement pads and rotors) and was never happy. Did the recommended break in but the brakes never had much stopping power. I dreaded needing to do an emergency stop. On to the TeraFlex. Install was pretty straightforward. It always takes me longer than what is stated, for these they said 2 hours. I spent probably 6 to 8 hours, including some trouble I had bleeding. Driving these work great! It’s nice to have some good initial bite when applying them. I’ve tried a few hard stops and they feel great. I’ve read in a few spots that you should upgrade the master cylinder and brake booster. Also, read in some places that some years don’t require the upgraded booster and master cylinder. My brakes work great with stock booster and master cylinder. Super happy and glad I made this purchase.
Review: Great stopping power! - Wow!!!! These brakes are awesome! I have a 2018 Jeep Wrangler Rubicon 4 door on 38” tires and it can lock all 4 tires up with no issues at all. They are awesome and I’d highly recommend them to anyone running larger tires. These would of even been fun when it was stock. It’s a really nice sense of security and something I’m really glad I invested in.
