🔧 Sorento - Rear Brake Pads & Rotor Replacement

You’ll remove the rear wheels, swap the rear brake pads and rotors, then reassemble and bed the brakes so they stop smoothly. On your Sorento, the biggest “gotcha” is the parking brake system: some trims use an Electronic Parking Brake (EPB) that must be put in service mode before compressing the caliper piston.

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

⚠️ Safety & Precautions

• 🛑 Support the Sorento with jack stands on solid ground; never rely on a jack.
• 🛑 If equipped with EPB, retract/enter service mode before pushing the piston in, or you can damage the caliper/EPB motor.
• 🛑 Brake dust is harmful; use brake cleaner and avoid blowing dust with compressed air.
• 🛑 Brakes get hot; let everything cool before starting.
• 🛑 Battery disconnect is typically not required, but keep ignition OFF unless doing EPB service mode steps.

📋 Before You Begin

• 🧱 Park on level ground, set the transmission to Park, and chock the front wheels.
• 🛑 Make sure the EPB is released before lifting the rear.
• 🧰 Put your tools and parts within reach; once a caliper is off, you don’t want to leave it hanging.
• 📝 Assumption: This procedure covers both rear brake setups—EPB calipers and cable parking brake. Follow the matching step below.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and lift the rear

• Use a 21mm socket and breaker bar to crack the rear lug nuts loose 1/2 turn (do not remove yet).
• Use a floor jack (rated 3-ton minimum) to lift the rear at the correct jacking point.
• Set the Sorento onto jack stands (rated 3-ton minimum, pair) and give it a firm shake test.

Step 2: Remove the rear wheels

• Use a 21mm socket and ratchet (3/8-inch drive) to remove the lug nuts and wheels.
• Keep lug nuts together per wheel.

Step 3: Put the parking brake system in the correct mode

• If your Sorento has EPB: Use an EPB service mode function (often called “Brake Pad Replacement Mode”) with a capable scan tool. This retracts the EPB motor so the piston can be compressed safely.
• If your Sorento has a cable parking brake: Ensure the parking brake is fully released and proceed.
• Definition: An EPB uses an electric motor to apply the parking brake instead of a cable.

Step 4: Remove the rear caliper (do not let it hang)

• Locate the two caliper slide bolts on the back side of the caliper.
• Use a 14mm socket (and a 14mm wrench on the slide pin flats if it spins) to remove the two slide bolts.
• Lift the caliper off the bracket and hang it from the suspension with a bungee cord.
• Definition: The caliper squeezes the pads onto the rotor; the slide pins let it move smoothly.

Step 5: Remove the old pads and inspect

• Pull the pads out of the bracket by hand. Use a flat trim/pry tool gently if they’re stuck.
• Check the slide pins for smooth movement (they should glide, not bind).
• Spray the bracket area with brake cleaner spray and wipe clean.

Step 6: Remove the caliper bracket

• Use a 17mm socket and breaker bar to remove the two caliper bracket bolts.
• Definition: The caliper bracket is the fixed mount that the pads sit in.
• Torque to 90–110 Nm (66–81 ft-lbs) when reinstalling.

Step 7: Remove the rotor

• If your rotor has a retaining screw, remove it with a Phillips screwdriver #3.
• Pull the rotor straight off. If it’s rust-stuck, tap the rotor hat with a dead-blow hammer to break it free.
• Use a wire brush to clean rust off the hub face (where the rotor sits).

Step 8: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray to remove packing oil.
• Install the rotor onto the hub. If it uses a retaining screw, reinstall it with a Phillips screwdriver #3.
• Apply a paper-thin film of anti-seize compound to the hub face only (avoid the rotor braking surfaces).

Step 9: Reinstall the caliper bracket and hardware

• Install the new pad hardware clips from the rear brake hardware kit into the bracket.
• Use a 17mm socket to reinstall the bracket bolts.
• Apply medium-strength threadlocker to clean bolt threads if recommended by your parts instructions.
• Torque to 90–110 Nm (66–81 ft-lbs).

Step 10: Compress the caliper piston

• Remove the brake fluid reservoir cap under the hood (this helps pressure release).
• Use a brake piston compressor tool (specialty) to slowly push the piston back in.
• If your Sorento has EPB: Only compress after EPB service mode is active/retracted.
• Watch the reservoir—if it looks like it may overflow, remove some fluid safely (do not spill on paint).
• Definition: A piston compressor tool presses the piston straight back without damaging it.

Step 11: Install the new pads and reinstall the caliper

• Apply a light coat of brake caliper grease (silicone-based) to pad ears where they touch the clips (not on friction material).
• Install the inner and outer pads into the bracket.
• Lower the caliper over the pads and line up the slide bolt holes.
• Use a 14mm socket to reinstall the slide bolts.
• Torque to 25–35 Nm (18–26 ft-lbs).

Step 12: Repeat on the other rear side

• Do the same rotor and pad replacement steps on the opposite rear wheel.
• Always replace pads/rotors in pairs.

Step 13: Reinstall wheels and torque lug nuts

• Reinstall wheels and hand-thread lug nuts.
• Lower the Sorento off the jack stands (rated 3-ton minimum, pair) using the floor jack (rated 3-ton minimum).
• Use a torque wrench (10–200 Nm range) and 21mm socket to tighten lug nuts in a star pattern.
• Torque to 110–120 Nm (81–89 ft-lbs).

✅ After Repair

• 🦶 Pump the brake pedal 10–15 times before moving the Sorento until the pedal feels firm.
• 🧴 Check brake fluid level and reinstall the reservoir cap.
• 🧠 If equipped with EPB, exit service mode and confirm the parking brake applies/releases normally.
• 🛣️ Do a careful test drive: start with low-speed stops, listen for grinding, and confirm straight braking.
• 🧩 Brake bedding (break-in): make 6–10 medium stops from ~50 km/h to ~15 km/h, with cool-down driving between stops. Definition: bedding transfers an even layer of pad material to the rotor to prevent vibration.
