🔧 F-150 - Rear Brake Pad and Rotor Replacement

This repair replaces the rear brake pads and both rear rotors on your F-150. The parking-brake shoes sit inside each rear rotor, so the parking brake must be fully released and may need adjustment before the rotors can be removed.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: Factory rear disc brakes and stock wheel hardware.

⚠️ Safety & Precautions

• ⚠️ Support your F-150 with jack stands. Never work under a vehicle supported only by a jack.
• 🛑 Chock both front wheels because the parking brake must remain released.
• 🧤 Wear gloves, safety glasses, and a dust mask. Do not blow brake dust away with compressed air.
• 🔥 Allow the brakes to cool completely before beginning.
• 🧱 Do not press the brake pedal while a caliper is removed.
• 🪝 Never let a caliper hang from its rubber brake hose.
• 🔋 Battery disconnection is not required, and your F-150 does not use an electronic parking brake.

📋 Before You Begin

• 📍 Park your F-150 on firm, level pavement. Shift into Park, switch off the engine, and remove the key.
• 🛑 Release the parking brake completely and place wheel chocks firmly against both sides of the front tires.
• 🧴 Open the hood and check the brake-fluid reservoir. If it is at the MAX line, remove a small amount before compressing the pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Wheel Nuts

• With the truck still on the ground, use the 21mm deep socket and 1/2-inch breaker bar to loosen each rear lug nut about one-half turn.
• Do not remove the lug nuts yet.

Step 2: Raise and Support the Truck

• Position the 3-ton floor jack beneath the center of the rear axle housing. Do not place it under the differential cover.
• Raise the rear until both tires clear the ground.
• Place the 3-ton jack stands beneath the axle tubes, close to the leaf springs.
• Lower the axle carefully onto the stands, then gently shake the truck to confirm it is stable.

Step 3: Remove the Rear Wheels

• Use the 21mm deep socket and 1/2-inch breaker bar to remove the lug nuts.
• Remove both rear wheels and lay them flat away from the work area.

Step 4: Remove the Brake Caliper

• Place the plastic drain pan below the brake assembly and clean loose dirt with non-chlorinated brake cleaner and the stiff nylon brake brush.
• Use the 13mm socket and 3/8-inch ratchet to remove the two caliper guide-pin bolts.
• If a guide pin turns, hold its flats with the 15mm open-end wrench while loosening the bolt.
• Lift the caliper off the pads and support it with the brake-caliper hanger.
• Do not disconnect the brake hose.

Step 5: Remove the Old Brake Pads

• Slide the inner and outer pads out of the caliper bracket by hand.
• Use the small flat-blade screwdriver to remove the stainless pad clips.
• Note the position of any wear indicator before discarding the old pads.
• Photograph the hardware before removing it.

Step 6: Compress the Caliper Pistons

• Check the brake-fluid reservoir before compression and watch the fluid level throughout this step.
• Place an old brake pad across the pistons, then use the rear brake piston compression tool to press both pistons slowly and evenly into the caliper.
• A piston compression tool applies steady pressure without damaging the piston faces.
• Stop if a piston binds, tilts, leaks, or will not retract. The caliper may require replacement.

Step 7: Remove the Caliper Bracket

• Use the 18mm socket and 1/2-inch breaker bar to remove the two caliper-bracket bolts.
• Lift the bracket away from the rotor.
• These bolts are tight. Keep the socket fully seated to prevent rounding the bolt heads.

Step 8: Retract the Parking-Brake Shoes if Needed

• Confirm again that the parking brake is fully released.
• Look through the adjustment opening in the rotor or backing plate. Remove the rubber access plug with the small flat-blade screwdriver if equipped.
• Use the large flat-blade screwdriver to rotate the star-wheel adjuster until the parking-brake shoes retract.
• The star wheel is a toothed adjuster that changes parking-brake shoe clearance.
• If the rotor begins moving but catches firmly, retract the shoes further rather than forcing the rotor off.

Step 9: Remove the Old Rotor

• Pull the rotor straight off the wheel studs.
• If rust holds it in place, strike the rotor hat between the wheel studs with the 16-ounce dead-blow hammer.
• Do not strike the studs, parking-brake components, or thin backing plate.
• Inspect the parking-brake shoes, springs, and adjuster. Replace damaged, contaminated, cracked, or separated shoes before continuing.

Step 10: Clean the Hub and Install the New Rotor

• Use the small wire brush to clean rust from the hub face and center pilot.
• Keep the brush away from parking-brake friction surfaces and seals.
• Clean both friction faces of the new rotor with non-chlorinated brake cleaner and the stiff nylon brake brush.
• Slide the new rotor over the studs and parking-brake shoes.
• The rotor must sit completely flush against the hub.

Step 11: Adjust the Parking Brake

• Use the large flat-blade screwdriver through the access opening to expand the star-wheel adjuster until the rotor develops light drag while turning by hand.
• Back the adjuster off slightly until the rotor turns freely with only a faint, even brushing sound.
• Reinstall the rubber access plug by hand if equipped.
• Repeat the same adjustment on the opposite side.

Step 12: Service and Install the Caliper Bracket

• Use the small wire brush to clean the bracket surfaces beneath the stainless pad clips.
• Install the new pad clips by hand. They must sit flat and must not touch the rotor.
• Remove each slide pin by hand, wipe it clean, and apply a thin coating of high-temperature ceramic brake lubricant.
• Do not place lubricant on the rotor or pad friction material.
• Install the bracket and start both bolts by hand.
• Use the 18mm socket and 1/2-inch torque wrench to tighten the rear caliper-bracket bolts to 165 Nm (122 ft-lbs).

Step 13: Install the New Brake Pads

• Apply a very thin film of high-temperature ceramic brake lubricant to the pad ears where they contact the stainless clips.
• Install the inner and outer pads into the bracket by hand.
• Confirm the pads slide smoothly without excessive looseness.
• Keep all lubricant away from the pad faces and rotor.

Step 14: Reinstall the Caliper

• Lower the caliper over the new pads without twisting the brake hose.
• Start both guide-pin bolts by hand.
• Use the 15mm open-end wrench to hold a guide pin if it turns.
• Use the 13mm socket and 3/8-inch torque wrench to tighten the guide-pin bolts to 36 Nm (27 ft-lbs).
• Remove the brake-caliper hanger and verify the hose is not kinked or rubbing.

Step 15: Repeat on the Opposite Side

• Use the same listed tools and repeat Steps 4 through 14 on the other rear brake assembly.
• Verify that both rotors rotate and that both parking-brake adjustments feel similar.

Step 16: Reinstall the Wheels

• Install each wheel and start all lug nuts by hand.
• Use the 21mm deep socket and 1/2-inch breaker bar to snug the nuts in a crossing pattern.
• Use the 3-ton floor jack to raise the axle slightly, remove the 3-ton jack stands, and lower the truck until the tires touch the ground.
• Use the 21mm deep socket and 1/2-inch torque wrench to tighten the lug nuts in a crossing pattern to 203 Nm (150 ft-lbs).

Step 17: Restore Brake-Pedal Pressure

• Before starting the engine, press and release the brake pedal slowly several times until it feels firm.
• Do not drive if the pedal remains soft or sinks toward the floor.
• Use the DOT 3 brake-fluid tester according to its instructions if the fluid appears dark or contaminated.
• Check the reservoir and add only fresh DOT 3 brake fluid if the level is below MAX.

✅ After Repair

• 🔍 Inspect around both calipers and hose connections for brake-fluid leaks.
• 🛑 Apply and release the parking brake several times. Confirm it holds the truck on a gentle incline and releases without either rear wheel dragging.
• 🚗 Perform a slow test in a safe area. Check braking at walking speed before driving normally.
• 🌡️ After the test, carefully check for unusual heat or a burning smell from either rear wheel. One side being much hotter indicates drag.
• 🛞 Recheck wheel-lug torque to 203 Nm (150 ft-lbs) after approximately 80-160 km.
• 📘 Follow the brake-pad manufacturer's bedding procedure. If none is supplied, make 8-10 moderate stops from approximately 50 km/h to 15 km/h, allowing cooling time between stops.
• ⏳ Avoid hard emergency-style stops and holding the hot brakes stationary during the first 300 km unless safety requires it.
