🔧 ES350 - Rear Brake Pads & Rotor Replacement

You’ll remove the rear wheels, swap the rear brake pads and rotors, then reassemble and torque everything correctly. This restores braking performance and helps prevent vibration or noise from worn or warped rotors.

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

Assumption: your ES350 uses a mechanical parking brake (no electronic EPB).

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands before working underneath.
• 🛑 Do not press the brake pedal while a caliper is off the rotor.
• 🛑 Brakes may contain dust—use brake cleaner, not compressed air.
• 🛑 Keep grease and oil off pad friction surfaces and rotors.
• 🛑 Parking brake must be fully released for rotor removal.

📋 Before You Begin

• 🅿️ Park on level ground, chock the front wheels, and release the parking brake.
• 📏 Crack the rear lug nuts loose slightly using a 21mm socket and breaker bar before lifting.
• 🧼 Open the hood and check brake fluid level; it may rise when compressing caliper pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Use a floor jack to lift the rear at the proper jacking point.
• Set the car down onto jack stands and keep the wheel chocks in place.
• Remove both rear wheels using a 21mm socket.

Step 2: Remove the rear caliper

• Turn the steering wheel is not needed; you’re working in the rear.
• Locate the rear brake caliper (the “clamp” that squeezes the pads).
• Use a 14mm socket and ratchet to remove the 2 caliper slide bolts.
• Lift the caliper off and hang it from the suspension using a brake caliper hanger hook (this prevents hose damage).

Step 3: Remove the pads and caliper bracket

• Pull the pads out by hand; use a flat-blade screwdriver gently if they’re stuck.
• The “caliper bracket” is the metal frame the pads sit in.
• Use a 17mm socket and breaker bar to remove the 2 caliper bracket bolts, then remove the bracket.

Step 4: Remove the rotor

• If the rotor slides off, remove it by hand.
• If it’s stuck, tap around the rotor “hat” with a rubber mallet.
• If it’s still stuck, thread two M8 x 1.25 bolts into the rotor’s push-off holes and tighten evenly with a ratchet until the rotor pops loose.
• If the rotor won’t come off, the parking brake shoes may be holding it; ensure the parking brake is fully released.

Step 5: Clean and prep for installation

• Use wire brush to clean rust from the hub face (where the rotor sits).
• Spray the new rotor friction surfaces with brake cleaner spray and wipe clean.
• Install the new rotor onto the hub.

Step 6: Reinstall the bracket and hardware

• Install the caliper bracket and start bolts by hand.
• Tighten using a 17mm socket and torque wrench: Torque to 98 N·m (72 ft-lbs).
• Install new pad abutment clips from the hardware kit (they snap into the bracket); use needle-nose pliers if needed.

Step 7: Service the slide pins

• Slide pins are the small “guide posts” the caliper moves on for even braking.
• Pull the slide pins out, wipe them clean, and apply a thin coat of silicone brake grease.
• Reinsert pins and make sure they move smoothly.

Step 8: Install new pads

• Install the new pads into the bracket.
• Only apply a thin film of silicone brake grease on pad ears/backing where they contact clips (not on friction material).
• Grease goes on contact points only.

Step 9: Compress the caliper piston and reinstall caliper

• Place an old pad against the piston face.
• Use a C-clamp (6") to slowly push the piston back into the caliper until fully seated.
• Reinstall the caliper over the new pads.
• Install the caliper slide bolts using a 14mm socket, then torque with a torque wrench: Torque to 34 N·m (25 ft-lbs).

Step 10: Reinstall wheels

• Reinstall both rear wheels using a 21mm socket.
• Lower the car off the jack stands using the floor jack.
• Torque lug nuts in a star pattern using a torque wrench: Torque to 103 N·m (76 ft-lbs).

✅ After Repair

• 🦶 Pump the brake pedal slowly 10–15 times until it feels firm (this seats the pistons).
• 🧴 Re-check brake fluid level and top off if needed.
• 🔍 Check for leaks and make sure both rear wheels spin freely with the parking brake released.
• 🛣️ Bed-in pads (general): make 6–10 moderate stops from 40–15 mph, then drive to cool brakes.
• 🎧 Listen for grinding or pulling on a careful test drive.
