Master The Art Of Brake Maintenance: How To Change Brake Fluid Nissan Altima

What to know

Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the calipers, which in turn squeeze the brake pads against the rotors to slow down your vehicle.
If you notice a decrease in braking performance, it could be a sign of worn brake pads, but it could also be due to contaminated brake fluid.
This kit typically includes a bleeder wrench, a clear hose, a container to catch the old fluid, and a pressure pump.

Are you looking to maintain your Nissan Altima‘s braking system and ensure optimal performance? Changing brake fluid is a crucial maintenance task that can significantly impact your car’s safety and handling. This guide will walk you through the process of how to change brake fluid Nissan Altima, providing detailed instructions and essential tips to ensure a successful fluid change.

Why Change Brake Fluid?

Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the calipers, which in turn squeeze the brake pads against the rotors to slow down your vehicle. Over time, brake fluid can absorb moisture from the air, leading to:

Reduced boiling point: Moisture lowers the boiling point of brake fluid, making it more susceptible to vaporizing under high pressure and temperature conditions. This can result in a spongy brake pedal and reduced braking effectiveness.
Corrosion: Moisture can cause corrosion in the brake lines, calipers, and other components, leading to leaks and potential brake failure.
Reduced performance: Contaminated brake fluid can affect the overall performance of your braking system, leading to a longer stopping distance and compromised safety.

When to Change Brake Fluid

The recommended interval for changing brake fluid varies depending on the manufacturer, but it’s generally every two years or 30,000 miles. However, it’s best to consult your Nissan Altima‘s owner’s manual for the specific recommendations. You should also consider changing brake fluid sooner if you notice any of the following signs:

Spongy brake pedal: A soft or spongy brake pedal can indicate air in the brake lines or contaminated fluid.
Reduced braking effectiveness: If you notice a decrease in braking performance, it could be a sign of worn brake pads, but it could also be due to contaminated brake fluid.
Fluid discoloration: Brake fluid should be clear or slightly amber in color. If it’s dark brown or black, it’s likely contaminated and needs to be replaced.
Fluid level is low: Check the brake fluid reservoir regularly and top it off if necessary. A low fluid level can indicate a leak.

Gather Your Supplies

Before you begin, ensure you have the following supplies:

New brake fluid: Use DOT 3 or DOT 4 brake fluid, as specified in your owner’s manual.
Brake fluid bleeder kit: This kit typically includes a bleeder wrench, a clear hose, a container to catch the old fluid, and a pressure pump.
Clean rags: Use these to clean up any spills or drips.
Protective gloves: Wear gloves to protect your hands from brake fluid.
Safety glasses: Wear safety glasses to protect your eyes from splashes.
Jack and jack stands: These are essential for lifting the vehicle safely.
Torque wrench: Use this to tighten the bleeder screws to the correct specifications.

Step-by-Step Guide to Changing Brake Fluid

1. Park the vehicle on a level surface and engage the parking brake.
2. Locate the brake fluid reservoir. It’s typically located under the hood, near the master cylinder.
3. Clean the area around the reservoir and the bleeder screws.
4. Open the reservoir cap and check the fluid level. It should be near the “Full” mark.
5. Open the bleeder screw on the rear passenger side wheel. This is the furthest wheel from the master cylinder and will be the first one to be bled.
6. Connect the bleeder hose to the bleeder screw and place the other end in the container.
7. Have a helper pump the brake pedal several times to build pressure.
8. While your helper holds the brake pedal down, open the bleeder screw slightly. This will allow the old fluid to flow out of the brake line.
9. Close the bleeder screw when the fluid starts to come out clear.
10. Repeat steps 7-9 until all the old fluid is bled out.
11. Repeat steps 5-10 for each wheel, starting with the rear passenger side, then rear driver‘s side, front passenger side, and finally the front driver’s side.
12. Once all the wheels have been bled, check the fluid level in the reservoir and top it off as needed.
13. Close the reservoir cap and test the brakes.

Tips for a Successful Brake Fluid Change

Use a clean container to catch the old brake fluid. This will prevent contamination of the new fluid.
Bleed the brakes in the correct order. This ensures that the air is purged from the system efficiently.
Don’t let the brake fluid reservoir run dry. This can introduce air into the system and make it difficult to bleed the brakes.
Use a pressure bleeder if available. This can make the bleeding process faster and easier.
Thoroughly clean up any spills or drips. Brake fluid can damage paint and other surfaces.

Final Thoughts: Your Brakes Are Your Safety Net

Changing brake fluid is a relatively simple maintenance task that can significantly impact the safety and performance of your Nissan Altima. By following these steps and using the proper tools and techniques, you can ensure that your brakes are in top condition and ready to provide reliable stopping power whenever you need it. Remember, regular maintenance is key to keeping your vehicle safe and reliable.
