Gather Your Tools and Supplies

Before you begin, ensure you have the following tools and supplies:

• New rear brake pads: Make sure you purchase the correct brake pads for your Lexus ES 350.
• Brake pad lubricant: This helps ensure smooth brake pad movement.
• Torque wrench: Essential for tightening lug nuts to the correct specifications.
• Jack and jack stands: For safely lifting the vehicle.
• Wheel wrench: To remove the lug nuts.
• Socket wrench set: For removing and tightening various bolts.
• C-clamp: To compress the brake caliper pistons.

• Flathead screwdriver: To release the brake caliper retaining clip.
• Penetrating fluid: To loosen rusted bolts.

Safety First: Essential Precautions

Before you start working on your car, it’s crucial to prioritize safety:

• Park on a level surface: This prevents the vehicle from rolling while you’re working.
• Engage the parking brake: An essential safety precaution.
• Chock the front wheels: This will prevent the vehicle from rolling forward.
• Wear safety glasses and gloves: This protects you from potential hazards.

Step 1: Jack Up the Vehicle

1. Locate the jack points: Refer to your owner’s manual for the recommended jack points on your Lexus ES 350.
2. Place the jack stands: Once the vehicle is lifted, secure it with jack stands for added safety.

Step 2: Remove the Rear Wheels

1. Loosen the lug nuts: Use your wheel wrench to loosen the lug nuts on the rear wheels.
2. Remove the wheels: Once the lug nuts are loose, lift the vehicle slightly and remove the wheels.

Step 3: Remove the Brake Caliper

1. Locate the brake caliper: It’s attached to the brake rotor with two bolts.
2. Remove the caliper retaining clip: Use a flathead screwdriver to release the clip holding the brake caliper to the brake hose.
3. Remove the brake caliper bolts: Use a socket wrench to remove the bolts holding the brake caliper to the brake rotor.
4. Hang the brake caliper: Carefully hang the brake caliper on the suspension using a wire or zip tie to prevent strain on the brake hose.

Step 4: Remove the Old Brake Pads

1. Remove the old brake pads: The brake pads are held in place by clips or pins. Gently push the old brake pads out of their slots.

Step 5: Compress the Brake Caliper Piston

1. Apply penetrating fluid: If the brake caliper piston is stuck, apply penetrating fluid to help loosen it.
2. Use a C-clamp: Place the C-clamp on the brake caliper piston and slowly compress it. This creates space for the new brake pads.

Step 6: Install the New Brake Pads

1. Apply brake pad lubricant: Lubricate the back of the new brake pads with brake pad lubricant. This ensures smooth movement within the caliper.
2. Install the new brake pads: Slide the new brake pads into their slots, making sure they are properly seated.

Step 7: Reinstall the Brake Caliper

1. Reinstall the brake caliper bolts: Tighten the bolts holding the brake caliper to the brake rotor to the specified torque.
2. Reattach the brake caliper retaining clip: Secure the retaining clip to the caliper.
3. Remove the hanging wire or zip tie: Remove the wire or zip tie that was holding the brake caliper.

Step 8: Reinstall the Wheels

1. Install the wheels: Carefully place the wheels back on the car.
2. Tighten the lug nuts: Tighten the lug nuts by hand first, then use the torque wrench to tighten them to the specified torque.
3. Lower the vehicle: Lower the vehicle using the jack and remove the jack stands.

Step 9: Check for Proper Function

1. Pump the brake pedal: Make sure the brake pedal feels firm and responsive.
2. Test drive: Take the vehicle for a short test drive to ensure the brakes are working properly.

Final Touches: Ensuring Success

• Clean up: Wipe away any grease or dirt from the brake components.
• Inspect brake rotors: Check the brake rotors for wear and tear. If they are excessively worn, they may need to be replaced as well.
• Record the work: Keep a record of the date and mileage when you replaced the brake pads. This will help you track future maintenance.
