The Delta Brake System, Front & Rear is part of the TeraFlex lineup for keeping a lifted, heavier Jeep stopping safely. It helps the brake system keep working correctly once the suspension has been lifted. Part number 4403450 and 4403480 fits the 2007-2026 Jeep Wrangler and Gladiator.
Not Included:
Brake fluid, wheels, emergency brake cables and installation labor are not included unless the listing names them.
Features
Made for lifted, heavier Jeeps
Each part is aimed at the braking and clearance problems that appear once a Jeep carries a lift, bigger tires or extra gear.
Keeps lines clear through travel
Longer lines, anchors and spacers keep brake lines, sensor wires and cables clear of the tires and suspension at full travel.
Bolt-on to factory mounting points
Most parts bolt to existing mounting points with hand tools, and the instructions call out any trimming or bleeding the job needs.
Serviceable with TeraFlex replacements
Replacement pads and anchors are available from TeraFlex, so the system can be maintained as parts wear.

Installation guides with torque values and bleeding steps are linked on the listings where TeraFlex publishes them.

Installation
Type: Brake upgrade and service parts · Install: Bolt-on; brake line work requires bleeding · Afterward: Bleed, test the pedal and drive with caution
Read the TeraFlex instructions for this part completely before starting, and have extra brake fluid on hand for any job that opens the lines. A certified mechanic is recommended. Test the brakes carefully before driving.
A printable wheel fitment template: cut it to your wheel's center bore and rotate it inside the back of the wheel to check Delta caliper clearance before installing the brakes.
Covers the Delta Brake Kit: check caliper clearance with the wheel fitment template first, then replace the front and rear calipers and rotors. On the JL the front backing plates are bent and the rear backing plate tips are trimmed. Each caliper is gravity bled through its ball-valve bleeder and then all four corners are bled manually. TeraFlex notes that the Delta pedal will feel softer, with more travel, than stock, and that Jeeps lifted 3" or more may need its brake line anchors.

About TeraFlex
TeraFlex is a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the lineup.
The company traces its history to the 1950s, when it began as MEPCO (Military Equipment Parts Company), one of the first companies anywhere to supply Jeep parts and accessories. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and the brand credits itself with the first suspension system for that coil-spring platform, a low-range gearing option for the 231 transfer case and the CRD60 high-pinion axle.
The current catalog covers full lift systems, the Falcon shock line and a long list of Wrangler and Gladiator upgrades, and the company is now carrying the same engineering approach to other vehicles as well.
