🔧 F-250 - Rear Brake Pads & Rotor Replacement

You’ll remove the rear wheels, unbolt the rear brake calipers, replace the pads and rotors, then reassemble and torque everything correctly. On your F-250, the parking brake is typically a small “drum brake” inside the rotor hat, so we’ll also check/adjust that so the new rotors fit and don’t drag.

Difficulty Level: Intermediate | Estimated Time: 2.5-4.5 hours

Assumption: Factory rear disc brakes with drum-in-hat parking brake (most F-250s).

⚠️ Safety & Precautions

• 🛑 Support the truck with jack stands on the frame; never rely on a jack.
• 🧱 Chock the front wheels and keep the truck on level ground.
• 🔥 Brakes get hot—work only when components are cool.
• 😷 Avoid breathing brake dust; use brake cleaner, not compressed air.
• 🪝 Do not let the caliper hang by the brake hose; support it with a hanger.
• ⚠️ Keep the parking brake released during rotor removal/installation.
• 🔋 Battery disconnect is not required for this job.

📋 Before You Begin

• 🅿️ Park on level ground, put the shifter in PARK, and release the parking brake.
• 🧱 Place wheel chocks in front of and behind at least one front tire.
• 🔧 Loosen rear lug nuts 1/2 turn with a 21mm socket and breaker bar before lifting.
• 🧰 A torque wrench is a tool that tightens bolts to an exact safe tightness (torque).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Use a floor jack under the rear axle housing to raise the rear.
• Place jack stands under the frame (both sides) and lower the truck onto them.
• Give the truck a firm shake to confirm it’s stable.

Step 2: Remove the rear wheels

• Remove lug nuts using a 21mm socket and ratchet.
• Remove both rear wheels and set them aside.

Step 3: Inspect before disassembly

• Check the brake hose for cracks/wetness and look for fluid leaks.
• Look at pad thickness and rotor condition (deep grooves, heavy rust lip, blue heat spots).

Step 4: Remove the caliper (do not stretch the hose)

• Remove the caliper slide pin bolts using a 13mm or 15mm socket and ratchet.
• Lift the caliper off the bracket.
• Hang the caliper using a brake caliper hanger hook (specialty); it’s a hook used to support the caliper so the hose isn’t damaged.

Step 5: Remove the brake pads and hardware

• Slide the pads out of the bracket by hand.
• Remove the stainless pad clips (hardware) from the bracket.
• Clean the bracket pad “rails” with a wire brush and spray with brake parts cleaner.

Step 6: Remove the caliper bracket

• Remove the bracket-to-knuckle bolts using an 18mm socket and breaker bar.
• Set the bracket aside.
• Torque spec (typical Super Duty): Torque to 230 Nm (170 ft-lbs).

Step 7: Remove the rotor (and deal with parking brake shoes if needed)

• Pull the rotor straight off the hub.
• If it’s stuck, tap the rotor hat with a rubber mallet while pulling outward.
• If the rotor won’t come off because of the parking brake shoes, locate the star-wheel adjuster through the access slot and turn it with a flat-blade screwdriver to back the shoes off.
• Tip: Small turns—don’t force the adjuster.

Step 8: Inspect the parking brake (drum-in-hat)

• Inspect the small parking brake shoes inside the assembly for cracked lining or missing material.
• If you see loose lining, heavy damage, or gear-oil contamination, stop and replace the parking brake shoes/hardware before continuing.

Step 9: Prep the hub and install the new rotor

• Clean the hub face with a wire brush and brake parts cleaner so the rotor sits flat.
• Clean both sides of the new rotor with brake parts cleaner to remove protective oil.
• Install the new rotor onto the hub.
• If the rotor drags hard on the parking brake shoes, back the star-wheel off a bit more with a flat-blade screwdriver.

Step 10: Reinstall the caliper bracket (with new hardware)

• Install new pad clips from the brake hardware kit into the bracket by hand.
• Reinstall the bracket bolts using an 18mm socket and breaker bar.
• Torque to 230 Nm (170 ft-lbs).

Step 11: Compress the caliper piston

• Remove the brake fluid reservoir cap under the hood (this helps fluid return).
• Use a C-clamp (6" or larger) to slowly press the caliper piston fully back in.
• Watch the reservoir so it doesn’t overflow; siphon a little out if needed (do not spill on paint).

Step 12: Install the new rear pads

• Apply a thin film of high-temperature brake grease where pads slide on the clips (not on pad friction material).
• Install the inner and outer pads into the bracket.

Step 13: Reinstall the caliper

• Set the caliper over the new pads.
• Install slide pin bolts using a 13mm or 15mm socket and ratchet.
• Torque spec (typical Super Duty): Torque to 32 Nm (24 ft-lbs).

Step 14: Adjust the parking brake for light drag (if needed)

• With the rotor installed, turn the star-wheel with a flat-blade screwdriver until you feel light, even drag when spinning the rotor by hand.
• Back off slightly until the rotor spins freely with just a faint rub.

Step 15: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread lug nuts.
• Lower the truck to the ground using the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench 1/2" drive.
• Torque to 224 Nm (165 ft-lbs).

Step 16: Repeat on the other rear side

• Perform the same steps on the opposite rear brake.
• Tip: Do one side at a time to match parts.

✅ After Repair

• 🦶 Pump the brake pedal slowly 10–15 times until it feels firm (this seats the pistons against the new pads).
• 🧴 Check brake fluid level and top off with DOT 3 brake fluid only if needed.
• 🅿️ Test the parking brake hold on a gentle incline at low speed (safe area).
• 🛣️ Bed-in the pads: make 8–10 moderate stops from 40 to 10 mph, letting brakes cool a bit between stops.
• 🔍 Re-check lug nut torque after ~50 miles: 224 Nm (165 ft-lbs).
