How To Modify 87'-93' Mustang Parking Brake

Please follow our recommended steps regarding parking brake modifications for rear disc brakes on your Fox Body Mustang. Also, for this video, our provided steps are with the car already disassembled, so we will not be covering those steps:

1. Loosen the small hex-head screw securing the parking brake light switch to the assembly and the ground wire as well.


2. Remove the (2) 10 mm parking brake assembly retaining bolts.


3. Remove the factory front cable from the assembly. This is done by pushing up on the cable so that you can free up the eyelet from the recess groove and remove the assembly from the car.


4. 1st Cut the small tab from the self-adjusting spring with a cutoff wheel.


5. Next, cut the top tab off as well. This is to ensure that the handle will sit flat and parallel with the floor instead of at an angle.


6. Weld the paw to the handle with the second to the last tooth engaged on the gear drive.


7. For this step you will need the correct front parking brake cable. Once removed you will cut in half to remove the receiver and floor seal.


8. Using an appropriate size drill bit in relation to the outside diameter of the threaded portion on the front cable, drill out the center hold in the receiver.


9. Take the front cable and position the eyelet into the recess groove on the parking brake assembly.


10. Transfer the seal to the new cable in the correct orientation.


11. Route the cable through the correct opening in the floor.


12. Reinstall the assembly back into the car.


13. From under the car slide the modified receiver over the threaded portion on the front cable in the correct orientation. Use (2) M8-1.25 nuts to secure the receiver in place. Leave a little loose.


14. Install the rear parking brake cables by routing through the guides underneath the car and hook the frontward eyelets into the receiver.


15. Run up the first nut until it touches the receiver and turn a few times to create tension on the rear cables. Once there is adequate tension you can run up the second nut until it snugs tight with the first nut.


16. Test for parking brake functionality and make adjustments as needed
