🔧 Sorento - Rear Brake Pad & Rotor Replacement
You’ll be removing the rear wheels, taking off the rear brake calipers (the clamp that squeezes the pads), swapping the rotors, and installing new pads. Doing it right prevents noise, vibration, and uneven braking, and it keeps your braking distance safe.
Difficulty Level: Intermediate | Estimated Time: 2.0-3.5 hours
⚠️ Safety & Precautions
- 🛑 Support your Sorento on jack stands, never the jack alone.
- 🔥 Brakes get extremely hot; work only when fully cool.
- 🧴 Brake dust is irritating; avoid blowing with air—use brake cleaner.
- 🧷 Do not let the caliper hang by the brake hose; use a hook/bungee.
- 🅿️ If your Sorento has an Electronic Parking Brake (EPB) switch, put EPB into maintenance mode before starting (steps below).
- 🔋 Battery disconnect is not required for this job, but keep the key away from the vehicle so EPB can’t auto-apply.

📋 Before You Begin
- 🧭 Park on level ground, straighten wheels, and place wheel chocks at the front wheels.
- 🛞 Crack the rear lug nuts loose 1/4 turn using a 21mm socket and breaker bar before lifting.
- 🅿️ Parking brake setup (choose your match):
- If you have an EPB switch on the console: you must retract EPB using a scan tool “maintenance mode.” Use an EPB-capable scan tool and select EPB > Pad Replacement Mode (wording varies).
- If you have a manual parking brake pedal/lever: release it fully and continue (no scan tool needed).
🔨 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 correct jacking point, then set the vehicle onto jack stands (rated 3-ton minimum).
- Shake the vehicle lightly to confirm it’s stable before you work.
Step 2: Remove the rear wheels
- Remove lug nuts using a 21mm socket and ratchet, then remove both rear wheels.
Step 3: Remove the rear caliper (the clamp)
- Turn the steering slightly if needed for access, then locate the two caliper slide bolts.
- Use a 14mm socket and ratchet to remove the caliper slide bolts.
- Lift the caliper off the bracket and hang it using a bungee cord or caliper hook.
- Never let the caliper dangle.
Step 4: Remove pads and the caliper bracket (the pad “frame”)
- Pull the old brake pads out of the bracket by hand (a flat-blade screwdriver helps if stuck).
- The “caliper bracket” is the heavy metal mount the pads sit in.
- Use a 17mm socket and breaker bar to remove the two caliper bracket bolts.
- Set the bracket aside.
Step 5: Remove the rotor
- If your rotor has a retaining screw, remove it using a Phillips screwdriver.
- Pull the rotor straight off the hub.
- If it’s stuck: spray around the hub with brake cleaner, tap the rotor hat area firmly (not the studs) and work it loose.
Step 6: Clean the hub and prep the new rotor
- Use a wire brush to clean rust off the hub face so the rotor sits flat.
- Clean the new rotor braking surfaces using brake cleaner and shop towels (removes anti-rust oil).
Step 7: Install the new rotor
- Place the new rotor onto the hub.
- If equipped with a retaining screw, install it with a Phillips screwdriver (snug only; it just holds the rotor during assembly).
Step 8: Reinstall the caliper bracket
- Apply a small amount of medium-strength threadlocker to the bracket bolt threads.
- Install the bracket bolts using a 17mm socket and ratchet, then tighten with a torque wrench.
- Torque to 98–118 Nm (72–87 ft-lbs)
Step 9: Service the slide pins and install new pad hardware
- Remove the slide pins from the bracket (they pull out by hand).
- Wipe them clean with shop towels, then apply a thin coat of brake caliper slide pin grease and reinstall.
- Replace the pad clips/hardware in the bracket (they snap in by hand; a flat-blade screwdriver helps).
Step 10: Compress the caliper piston
- Remove the brake fluid reservoir cap under the hood (loosely) so fluid can move.
- Use a C-clamp or brake caliper compression tool (specialty) to slowly push the caliper piston back in.
- If the piston won’t press in smoothly: stop and re-check that the parking brake is fully released / EPB is in maintenance mode.
- Compress slowly to avoid fluid overflow.
Step 11: Install the new pads and reinstall the caliper
- Install the new pads into the bracket.
- Place the caliper over the pads.
- Install the slide bolts using a 14mm socket and ratchet, then tighten with a torque wrench.
- Torque to 25–35 Nm (18–26 ft-lbs)
Step 12: Repeat on the other rear side
- Repeat Steps 3 through 11 on the opposite rear wheel.
Step 13: Reinstall wheels and lower
- Reinstall wheels and hand-thread lug nuts.
- Lower the vehicle using the floor jack (rated 3-ton minimum).
- Tighten lug nuts in a star pattern using a torque wrench.
- Torque to 90–110 Nm (66–81 ft-lbs)
✅ After Repair
- 🦶 Pump the brake pedal 10–15 times before driving until it feels firm (this seats the pads to the rotors).
- 🧯 Check brake fluid level; top up only if needed (don’t overfill).
- 🅿️ If you have EPB: use your scan tool to exit maintenance mode, then apply/release EPB and confirm normal operation.
- 🧪 Test drive at low speed first; confirm no grinding, pulling, or warning lights.
- 🛣️ Pad bedding (recommended): make 6–8 smooth stops from ~40 km/h to 10 km/h with light-to-medium pressure, then drive 5–10 minutes to cool.
