Warnings

Tools required

Parts

• Parking brake cable assembly (specify left or right rear) × 1 — Use OEM specification
• Cable retaining clips (if damaged) × 1 — Use OEM specification
• Thread locker (medium strength) × 1 — Loctite 242 or equivalent

Preparation

1. Park vehicle on level, solid surface and place transmission in PARK
2. Place wheel chocks firmly against both front wheels
3. Release parking brake pedal/lever completely inside vehicle
4. Loosen rear wheel lug nuts 1/4 turn while vehicle is on ground
5. Raise rear of vehicle using floor jack at designated lift points
6. Support vehicle securely on jack stands rated for vehicle weight at proper frame support points
7. Remove rear wheels completely and set aside
8. Spray all cable mounting points, brackets, and equalizer nut with penetrating lubricant and allow to soak 10-15 minutes

Procedure

1. 1

   Access rear brake assembly
   Inspect the rear brake caliper and rotor area to locate the parking brake cable connection point at the caliper actuator lever. On 2021-2024 F-150 models, the parking brake cable connects to the caliper-integrated parking brake mechanism on the inboard side of the caliper.
2. 2

   Disconnect cable from caliper
   Using pliers, compress the cable retaining clip or remove the retaining pin securing the cable end to the parking brake actuator lever on the caliper. Carefully disconnect the cable end from the lever. Note the routing and orientation of any cable guides or retaining clips for reinstallation. The cable may be under slight tension even with parking brake released.
   ⚠Cable may snap back when disconnected. Keep hands clear of the cable path.
3. 3

   Remove cable bracket fasteners
   Working from the caliper toward the center of the vehicle, locate all cable bracket mounting points along the frame rail and rear suspension components. Remove all cable bracket bolts securing the cable to the frame, axle housing, and body. On this model, there are typically 3-4 bracket locations per side. Keep track of bracket positions and hardware for reassembly.

4. 4

   Access cable equalizer assembly
   Locate the parking brake cable equalizer assembly at the center of the vehicle, typically mounted to the frame crossmember ahead of the rear axle. The equalizer connects both left and right cables and allows for tension adjustment. Clean the area around the equalizer nut with a wire brush if corroded.
5. 5

   Loosen equalizer nut
   Using appropriate socket or wrench, loosen the equalizer nut that adjusts cable tension. This nut threads onto the threaded rod connecting both cable assemblies. Back the nut off completely but do not remove the equalizer assembly unless replacing both cables. Note the current position of the nut for reference during adjustment.
   ⚠Once equalizer nut is loosened, cables will have minimal tension. Support cables to prevent sudden movement.

   Equalizer Nut15 Nm (11 lb-ft)
6. 6

   Disconnect cable from equalizer
   Remove the cable end from the equalizer assembly. This typically involves removing a retaining clip or pin and sliding the cable end out of the equalizer bracket. On some configurations, the cable ball-end fits into a slotted bracket. Note the exact orientation and connection method for the replacement cable.
7. 7

   Remove cable from vehicle
   Trace the cable forward to its connection point at the parking brake pedal or lever inside the vehicle cabin. This may require removing lower dash panels or accessing the cable through the floor pan. Disconnect the cable from the pedal assembly using appropriate clips or fasteners. Pull the cable through any grommets in the floor pan, noting routing for replacement cable installation.
8. 8

   Install new cable assembly
   Route the new parking brake cable from the cabin through the floor pan grommet, following the exact path of the original cable. Connect the front end to the parking brake pedal assembly using the appropriate retaining clips. Ensure the cable seats fully in all mounting points and the grommet seals properly to prevent water and exhaust intrusion into the cabin.
9. 9

   Route and secure cable
   Route the cable along the frame rail and rear suspension, installing all cable bracket bolts at their original locations. Ensure the cable does not contact the driveshaft, exhaust components, suspension travel paths, or any sharp edges. Cable routing must match factory configuration to prevent binding or damage. Torque all cable bracket bolts to specification in sequence from front to rear.
   ⚠Verify cable has adequate clearance through full suspension travel before final tightening.

    Connect cable to equalizer
    Connect the cable end to the equalizer assembly in the same configuration as the original. Install any retaining clips or pins securely. Ensure the cable end is fully seated in the equalizer bracket and cannot disengage under tension.
11. 11

    Connect cable to caliper
    At the rear caliper, connect the cable end to the parking brake actuator lever. Install the retaining clip or pin to secure the cable end. Verify the cable moves freely and the actuator lever returns to the rest position when released. Check that cable routing through any caliper brackets or guides matches the original configuration.
12. 12

    Adjust cable tension
    Thread the equalizer nut onto the threaded rod to adjust parking brake cable tension. Initial adjustment: tighten the equalizer nut until slight resistance is felt when rotating the rear rotors by hand. The goal is minimal drag with parking brake released. Do not over-tighten at this stage. Torque the equalizer nut to specification once proper adjustment is achieved.
    ⚠Over-tightening the equalizer nut will cause rear brake drag, premature wear, and reduced fuel economy. Adjustment must be verified per step 14.

    Reinstall wheels
    Clean wheel mounting surfaces on hub and wheel. Install rear wheels and thread lug nuts by hand to prevent cross-threading. Lower vehicle until wheels just contact ground but vehicle weight is still on jack stands. Torque lug nuts to specification in a star pattern. Fully lower vehicle and remove jack stands. Perform final lug nut torque verification in star pattern with vehicle on ground.

    Final adjustment and functional test
    With vehicle on ground and engine off, apply and release parking brake 10-15 times to seat cables and allow self-adjustment (if equipped with self-adjusting mechanism). Test parking brake: it should engage firmly within 3-6 clicks or 2-3 inches of pedal travel. Verify rear wheels are locked when parking brake is fully applied. Adjust equalizer nut as needed to achieve proper engagement. After adjustment is correct, torque equalizer nut to final specification.
    ⚠️Do not operate vehicle until parking brake adjustment is verified. Improper adjustment can result in vehicle rollaway.

Reassembly

1. Verify all cable bracket bolts are torqued to specification and no hardware was left loose
2. Confirm cable routing does not interfere with suspension travel, driveshaft, or exhaust components
3. Check that floor pan grommet is properly sealed to prevent exhaust or water intrusion
4. Verify parking brake pedal returns fully to released position and indicator light extinguishes

Verification

• With parking brake released, verify rear wheels rotate freely with minimal drag
• Apply parking brake fully - rear wheels should be completely locked and unable to rotate
• Test on a slope: With parking brake engaged and transmission in neutral, vehicle should remain stationary on a 20% grade
• Check parking brake warning light illuminates when engaged and extinguishes when released
• Verify no unusual noises or binding during parking brake application and release
• After test drive, recheck all cable bracket bolts and equalizer nut for proper torque
• Confirm no rear brake drag by checking for normal wheel rotation and no excessive heat at rear rotors after short drive
