Quadratec Part No: 12700.400 Manufacturer Part No: 004354420
The TeraFlex disc brake kit is manufactured within exact tolerances to provide the crucial stopping power that larger tires, and extreme off road situations demand. The TeraFlex disc brake kit is ideal for anyone wanting to upgrade a quality disc brake package to their axles. This disc brake kit is intended for use as a bolt-on upgrade to replace factory Jeep® drum brakes. The internal drum parking brake provides outstanding holding power when compared to other disc brake conversions.
Some factory Jeep® 15" Wheels may rub on the caliper. Do NOT operate the vehicle until you confirm adequate caliper/wheel clearance.
The heavy duty caliper is designed to offer
superior stopping power compared to the
stock drum configuration.
The caliper is manufactured using a tight tolerance casting process. The machined surfaces allow the piston to effectively transfer
heat for proper cooling.
The integrated emergency brake system
makes the disc brake conversion a simple
and easy modification. The emergency
brake is designed to work with the integrated
drum cast and machined into the rotor. New E-Brake Cables are available separately for a no hassle conversion.
The late model Jeep® specific bolt pattern
backing plate is designed from heavy duty
steel for superior strength, and the dust
shield keeps debris from reaching critical
The rotor is designed to offer excellent
heat dissipation, with resistance to cracking.
The rotor is machined on the disc mounting
surface as well as the integrated emergency
brake surface to ensure parallel and even
braking performance. Dual bolt pattern (5x4.5
& 5x5.5) allow multiple wheel choices.
Late Model Jeep Bolt Pattern Shown
This kit does not work with ABS sensors. You will not be able to install the ABS
sensors into the disc brake mount backing plate.
Some factory Jeep® 15" Wheels may rub on the caliper. Do NOT operate the
vehicle until you confirm adequate caliper/wheel clearance.
TeraFlex does not make any Disc Brake Kits to fit factory Jeep® axles built prior to the YJ Wrangler, except for the XJ Cherokee axles.
The years between 1987 and 1991 are the dark years where anything is possible
from Jeep®, so check the bolt pattern with the drawing before ordering a kit.
Most aftermarket wheels, especially alloy wheels require longer wheel studs when installing this kit. To make up for the thickness of the rotor. Use NAPA p/n 641-3204 for the longer Jeep® rear axle stud.
If you don't want to replace the wheel bearings it is okay to cut a slot in the preload ring and slide it over the axle shaft.
