Can You Spray Brake Cleaner On The Rotors?

Last Updated on October 6, 2023 by Matthew Lloyd

Yes, You can spray brake cleaner on rotors to effectively clean and maintain them. Cleaning brake rotors is important in ensuring optimal braking performance and prolonging their lifespan. Brake cleaner helps remove dirt, grime, brake dust, and other contaminants that can accumulate on the rotor surface and impact braking efficiency. However, it’s essential to follow proper safety precautions when using brake cleaner and handle it carefully.

Why It’s Important to Clean Your Brake Rotors?

The Importance of Cleaning Brake Rotors: Regularly cleaning your brake rotors provides numerous benefits that contribute to your braking system’s overall performance and longevity. Let’s explore why cleaning your brake rotors is important:

Preventing Squealing Brakes: Brake dust is a common culprit behind annoying brake squeals. By cleaning your rotors, you can minimize the accumulation of brake dust, reducing the chances of experiencing squealing brakes.

Detecting Underlying Issues: Brake dust and road grime can mask potential problems within your braking system. Cleaning the rotors allows for better visibility, making identifying issues such as caliper leaks or worn brake pads easier.

Preventing Contamination: During brake pad installation, it’s possible to get brake grease on the rotor surface inadvertently. Cleaning the rotors helps prevent contamination, ensuring optimal performance from your new brake pads.

Signs Indicating the Need for Brake Rotor Cleaning

Before proceeding with the cleaning process, it’s essential to recognize common signs that suggest your brake rotors may require cleaning:

1. Squealing or Unusual Noises: If you hear squealing or uncommon sounds when applying the brakes, it could indicate dirty brake rotors.
2. Vehicle Pulling to One Side: When braking, if your vehicle tends to pull to one side, it might suggest uneven brake pad wear due to dirty rotors.
3. Vibrating or Pulsating Brake Pedal: If you experience a vibrating or pulsating sensation in the brake pedal or steering wheel during braking, it could be due to dirt or debris on the rotors.
4. Longer Stopping Distances: If you notice that your vehicle requires more distance to come to a complete stop, dirty rotors may be compromising the efficiency of your braking system.

How to Clean Your Brake Rotors With Brake Cleaner?

Step 1: Prepare for Safety

• Wear safety goggles to protect your eyes from any splashes or fumes.
• Ensure the area is well-ventilated or work in an open space to avoid inhaling excessive fumes.

Step 2: Lift the Vehicle

• Use a jack to lift the vehicle and secure it with jack stands for safety.

Step 3: Remove the Wheels

• Remove the wheels to gain access to the brake rotors.
• Place a tray or cloth underneath the rotor to catch any runoff during cleaning.

Step 4: Spray Brake Cleaner

• Shake the brake rotor cleaner can well before use.
• Hold the can at a safe distance from the rotor and spray the brake cleaner all over the front and back surfaces of the rotor.
• Ensure thorough coverage, paying attention to the areas with visible dirt, grime, or brake dust.

Step 5: Wipe Down the Rotor

• Take a clean rag or microfiber cloth and wipe down the rotor surface.
• Use gentle pressure to remove any remaining dirt or residue.
• Repeat the process until the rotor appears clean and dry.

Step 6: Optional – Dealing with Stubborn Rust or Grime

• If the rotor has stubborn rust or grime, you can apply more brake cleaner.
• Use a wire brush or steel wool to work the surface and remove the persistent contaminants.
• Wipe down the rotor again with a clean cloth or rag.

Step 7: Repeat for Other Rotors

• Follow the same process for all the other rotors on your vehicle.
• Ensure each rotor is thoroughly cleaned and dry before moving on to the next one.

By following these steps, you can effectively clean your brake rotors using brake cleaner. Remember to exercise caution, wear safety goggles, and work in a well-ventilated area. It’s also important to use a clean cloth or rag and avoid touching the rotor surface with your hands to prevent oil or grease contamination.

Tips for Cleaning Brake Rotors

Consider the following tips to enhance your brake rotor cleaning process:

1. Always wear safety goggles and protective gloves when using brake cleaner to prevent any potential accidents or eye irritation.
2. Use brake cleaner in a well-ventilated area or outdoors to avoid inhaling fumes.
3. If using hot, soapy water for cleaning, ensure the rotor is completely dry before reinstallation to prevent rust formation.
4. Avoid touching the rotor surface with bare hands to prevent oil or dirt transfer. Handle the rotor with clean gloves or use a clean cloth if necessary.
5. Clean both sides of the rotor to ensure cleanliness and optimal braking performance.
