Protect Your Nissan Altima: Essential Guide to Changing Brake Fluid (DIY)

Changing your brake fluid is an essential maintenance task that helps ensure the safety and performance of your Nissan Altima. Brake fluid plays a crucial role in transmitting hydraulic pressure from the master cylinder to the wheel cylinders or calipers, allowing you to apply braking force to the wheels. Over time, brake fluid can become contaminated with water and other impurities, which can reduce its effectiveness and lead to brake problems.

Understanding the Importance of Changing Brake Fluid

Brake fluid is hygroscopic, meaning it absorbs moisture from the air. As moisture accumulates in the brake fluid, it can cause corrosion within the brake system, leading to leaks, reduced braking performance, and potentially even brake failure. Additionally, moisture in the brake fluid can lower its boiling point, which can lead to vapor lock and a loss of braking power under extreme braking conditions.

Frequency of Brake Fluid Changes

The recommended frequency for changing brake fluid varies depending on the manufacturer and the driving conditions. For most Nissan Altimas, it is recommended to change the brake fluid every two years or 30,000 miles, whichever comes first. However, if you drive in particularly harsh conditions, such as frequent stop-and-go traffic or in areas with high humidity, you may need to change your brake fluid more often.

Tools and Materials Required

Before you begin changing your brake fluid, gather the following tools and materials:

• New DOT 3 or DOT 4 brake fluid
• Brake fluid bleeder kit
• 10mm wrench
• 12mm wrench
• Clean rags
• Gloves

Step-by-Step Guide to Changing Brake Fluid Nissan Altima

1. Safety First

Always park your Nissan Altima on a level surface and engage the parking brake to prevent it from rolling. Allow the vehicle to cool down if it has been recently driven.

2. Locate the Brake Fluid Reservoir

The brake fluid reservoir is typically located in the engine compartment, near the master cylinder. It is usually a translucent plastic container with a black or blue cap.

3. Remove the Reservoir Cap

Carefully remove the cap from the brake fluid reservoir. Be prepared for some brake fluid to spill out, so place a clean rag under the reservoir.

4. Connect the Bleeder Kit

Attach the brake fluid bleeder kit to the bleeder screw on the wheel cylinder or caliper that is farthest from the master cylinder. Typically, this will be the rear right wheel.

5. Open the Bleeder Screw

Using a 10mm wrench, carefully open the bleeder screw by turning it counterclockwise. Allow the old brake fluid to drain into the collection container of the bleeder kit.

6. Add New Brake Fluid

While someone is depressing the brake pedal, slowly add new brake fluid to the reservoir. Continue adding fluid until the old fluid is completely flushed out and the new fluid is flowing out of the bleeder screw.

7. Close the Bleeder Screw

Once the new fluid is flowing out of the bleeder screw, close it by turning it clockwise using the 10mm wrench. Tighten it securely, but do not overtighten.

8. Repeat for Other Wheels

Follow the same procedure for the remaining wheels, working from the farthest to the closest to the master cylinder.

9. Check Brake Fluid Level

After bleeding all four wheels, check the brake fluid level in the reservoir and top it off if necessary.

10. Inspect the Brake System

Once the brake fluid has been changed, inspect the entire brake system for any leaks or damage. If you find any issues, have them repaired immediately.

Tips for Changing Brake Fluid Nissan Altima

• Use only DOT 3 or DOT 4 brake fluid recommended by Nissan.
• Do not mix different types of brake fluid.
• If you spill any brake fluid on the paint of your Nissan Altima, rinse it off immediately with water.
• Dispose of the old brake fluid properly according to local regulations.
• If you are not comfortable changing your brake fluid yourself, have it done by a qualified mechanic.

Beyond Changing Brake Fluid: Maintaining Your Nissan Altima’s Brake System

Changing your brake fluid is an important part of maintaining your Nissan Altima’s brake system, but there are other essential maintenance tasks that should not be neglected:

• Inspect brake pads and rotors: Brake pads and rotors wear down over time and need to be replaced when they reach a certain thickness.
• Lubricate brake calipers: Brake calipers should be lubricated regularly to prevent them from sticking and causing uneven braking.
• Flush the brake lines: Brake lines can become clogged with debris over time, which can restrict the flow of brake fluid and reduce braking performance.

By following these maintenance tips, you can help ensure that your Nissan Altima’s brake system is always functioning properly, keeping you and your passengers safe on the road.

Brake Fluid Change: A Key Component of Nissan Altima Maintenance

Regularly changing your brake fluid is a crucial aspect of maintaining your Nissan Altima’s braking system.
