🔧 Sedona - Rear Brake Pads & Rotor Replacement

You’ll remove the rear wheels, take off the rear brake calipers and brackets, replace the rear rotors and brake pads, then reassemble and verify proper brake pedal feel. This restores safe stopping power and prevents vibration/pulsation from worn or warped rotors.

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

⚠️ Safety & Precautions

• 🛑 Support the van with jack stands—never rely on a floor jack alone.
• 🛑 Chock the front wheels so the van can’t roll while the rear is lifted.
• 🛑 Brake dust is harmful—wear a mask and use brake cleaner, not compressed air.
• 🛑 Brakes may be hot—let components cool before touching.
• 🛑 Keep brake fluid off paint; it removes paint quickly.
• 🛑 Battery disconnect is not required for this repair.

📋 Before You Begin

• 🅿️ Park on level ground and set the parking brake.
• 🧱 Place wheel chocks in front of both front tires.
• 🔧 Loosen the rear lug nuts 1/2 turn before lifting (use 21mm socket and breaker bar).
• 📌 C-clamp compressor = clamp that pushes piston back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Use a floor jack (rated 3-ton minimum) to lift the rear at the approved rear lift point.
• Set the van down onto jack stands (rated 3-ton minimum) under solid suspension/body support points.
• Remove the rear wheels using a 21mm socket and ratchet.

Step 2: Remove the rear caliper (do not let it hang)

• Turn the steering wheel is not needed for the rear; just ensure you have good access.
• Remove the caliper slide bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket, then support it with a bungee cord.
• Never let the caliper hang by the hose.

Step 3: Remove old pads and inspect

• Remove the inner and outer pads by hand; use a flathead screwdriver gently if they’re stuck.
• Check the caliper slide pins (they should move smoothly). If dirty, clean and re-grease using high-temp brake grease.
• Spray dust and grime with brake cleaner spray (wear dust mask and safety glasses).

Step 4: Remove the caliper bracket

• Remove the caliper bracket bolts using a 17mm socket and breaker bar.
• Set the bracket aside and keep track of the hardware.
• Torque to 88-98 Nm (65-72 ft-lbs) when reinstalling (typical for this application).

Step 5: Remove the rotor

• If your rotor has a retaining screw, remove it with a Phillips #3 screwdriver.
• If it’s seized, use an impact driver (specialty) with the Phillips bit to break it free.
• Pull the rotor off. If stuck, tap the rotor hat with a rubber mallet while pulling outward.
• If the rotor won’t come off, the parking brake shoes may be holding it (many Sedona setups use a small drum-style parking brake inside the rotor “hat”): use a flathead screwdriver through the access hole to back off the adjuster slightly, then retry.

Step 6: Clean the hub and install the new rotor

• Use a wire brush to clean rust from the hub face (this helps prevent rotor wobble).
• Spray the new rotor with brake cleaner spray to remove protective oil.
• Install the new rotor. Reinstall the retaining screw (if equipped) using a Phillips #3 screwdriver.

Step 7: Compress the caliper piston

• Remove the brake fluid reservoir cap under the hood (helps fluid move back easier).
• Place an old pad against the piston face, then compress the piston using a C-clamp brake piston compressor.
• Go slowly and watch the brake fluid level so it doesn’t overflow.
• Slow compression helps prevent seal damage.

Step 8: Install new hardware and pads

• Replace the pad abutment clips (from the rear brake hardware kit) on the bracket.
• Apply a thin layer of high-temp brake grease where the pad “ears” contact the clips (keep grease off pad friction material and rotor).
• Install the new pads into the bracket.

Step 9: Reinstall bracket and caliper

• Reinstall the caliper bracket bolts using a 17mm socket and torque wrench: Torque to 88-98 Nm (65-72 ft-lbs).
• Slide the caliper over the new pads and install the slide bolts using a 14mm socket and torque wrench: Torque to 24-34 Nm (18-25 ft-lbs).

Step 10: Reinstall wheels

• Reinstall the wheels and hand-thread the lug nuts.
• Lower the van off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench (10-150 ft-lbs): Torque to 108-118 Nm (80-87 ft-lbs).

✅ After Repair

• 🦶 Pump the brake pedal 10-15 times before driving until it feels firm (this seats the pistons against the new pads).
• 🧪 Check brake fluid level and top off with DOT 3 / DOT 4 if needed.
• 👂 With the engine running, confirm normal pedal feel and that no grinding noises are present.
• 🚗 Bed-in the pads: make 6-10 moderate stops from ~30 mph down to ~5 mph, allowing short cool-down between stops.
• 🔎 Check for leaks around each caliper and re-check lug nut torque after a short drive.
