This tutorial provides a comprehensive guide on how to replace the front and rear brakes and rotors on a 2015 Lexus RC350. Whether you're a DIY enthusiast or just looking to save some money, this step-by-step guide will walk you through the process using factory service manual methods.

Step 1: Gather Your Tools and Materials

Before you start, make sure you have all the necessary tools and materials on hand. Here’s what you need:

• Torque wrench
• Speedi-Bleed pressure bleeder
• Brake grease (silicone and moly types)
• Wire wheel for drills/drivers
• Wire brush kit
• Replacement brake pads and rotors

Common Pitfalls

• Ensure your car is on a level surface and securely raised using jack stands.
• Avoid using any tools that are not rated for automotive work.

Step 2: Remove the Wheels

1. Loosen the lug nuts on the wheel using a lug wrench.
2. Lift the car using a jack and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel to access the brake components.

Step 3: Remove the Brake Caliper

1. Locate the caliper bolts and remove them using a socket and ratchet.
   • Front caliper bolts: torque to 100 lbs/ft
   • Rear caliper bolts: torque to 20 lbs/ft
2. Carefully slide the caliper off the rotor and support it using a bungee cord or similar to avoid strain on the brake line.

Step 4: Replace the Brake Pads

1. Remove the old brake pads from the caliper bracket.
2. Apply brake grease to the back of the new pads to reduce noise and ensure smooth operation.
3. Install the new pads into the caliper bracket.

Step 5: Replace the Rotors

1. If the rotor is held in place by screws, remove these screws.
2. Slide the old rotor off the hub and replace it with the new rotor. Ensure it is properly seated.
3. If necessary, clean the rotor surface with a wire brush to remove any debris or rust.

Step 6: Reinstall the Brake Caliper

1. Position the caliper back over the new pads and rotor.
2. Reinsert and tighten the caliper bolts.
   • Rear caliper bracket bolts: torque to 92 lbs/ft

Step 7: Bleed the Brakes

1. If you’ve opened the brake lines, use the Speedi-Bleed pressure bleeder to remove air from the brake system.
2. Start with the rear brakes, then move to the front, ensuring all air bubbles are expelled.

Step 8: Reattach the Wheels

1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the car from the jack stands and tighten the lug nuts to the specified torque.

Conclusion

Replacing the brakes and rotors on your Lexus RC350 can be a rewarding DIY project. Remember to take your time and follow each step carefully. After completing the installation, it’s advisable to test drive the vehicle at low speeds to ensure everything is functioning correctly. Regular brake maintenance is key to vehicle safety, so keep an eye on your brake performance and schedule replacements as needed.
