|1. Chock your front tires, release the parking brake, place a floor jack under the rear differential and then raise the back end of your Jeep JK Wrangler until the tires come off the ground and can rotate freely.
|2. While it’s not required to do so, you may find it much easier to remove the wheels and brake calipers in order to get to the rubber access hole plug and make adjustments through it. For the purposes of this write-up, that’s what I did and if you would like information on how to do remove the brake calipers, simply click on the write-up link below:

|3. Remove the rubber access hole plug on your Jeep JK Wrangler’s brake backing plate as shown in this pic.
|4.Insert a brake spoon into the access hole so that it engages the teeth on the adjuster screw. Then, rotate the adjuster screw up until there is a slight drag when you rotate your Jeep’s wheel.
|5. Using a small flat head screwdriver, push and hold the adjuster lever away from the adjuster screw star wheel and then back it off with the brake spoon until it no longer drags when you rotate your Jeep’s wheel. Reinstall the access hole rubber plug and repeat process on the opposite side. Try to get both sides adjusted equally. To help give you a better understanding of what’s going on inside, please refer to the diagram to the left.
1) Star wheel adjuster
2) Adjuster lever
3) Brake shoe
4) Small flathead screwdriver
5) Brake spoon
6) Brake shoe spring
|6. Once everything has been adjusted, reinstall your wheels, tighten the lug nuts to 95 ft. lbs. of torque and then lower your Jeep JK Wrangler back on to the ground. Test out your emergency/parking hand brake by pulling up on it and check to see if it keeps your JK from moving. If everything went according to plan, you should find that the brake lever won’t be able to lift up very high anymore and it should have a lot more bite.
And that’s it. Your Jeep JK Wrangler’s emergency/parking hand brake should be working well again. Please let me know if you have any questions.
