Properly flushing and refilling the brake fluid in a Nissan begins with acquiring the necessary tools, including a brake fluid tester and extractor, suitable wrenches, and clean containers. Identify the correct brake fluid type, such as DOT 3 or DOT 4, based on driving needs. Park on a stable surface, engage the parking brake, and clean around the fluid reservoir. Drain the old fluid through the brake bleeder valves, ensuring the reservoir remains filled to prevent air entry. After refilling with new fluid, test the brake system for leaks and performance. Further steps and potential issues are thoroughly addressed.
Gather Necessary Tools
Gather the tools you'll need before you start changing the brake fluid in a Nissan. This will make the job easier and help avoid problems like brake fluid contamination. Here's what you'll need:
- Brake Fluid Tester: Checks the quality of the brake fluid.
- Brake Fluid Extractor: Removes old brake fluid.
- Wrenches: Use the size that fits your Nissan model.
When you change the brake fluid, keep in mind that it can get contaminated in different ways. Moisture from the air or mixing different fluids can cause issues.
Use a clean container for the new fluid and a different one for the old fluid. An automotive funnel can help you pour the fluid without spilling.
Wear gloves and safety goggles to protect yourself from the chemicals in the brake fluid.
Identify Brake Fluid Type
To keep your Nissan's brakes working well, use the right brake fluid. Nissan cars usually need DOT 3, DOT 4, or DOT 5.1 brake fluids. Each type has different boiling points and works best under certain conditions.
- DOT 3: Common and affordable, good for everyday driving.
- DOT 4: Higher boiling point, better for hot climates or active driving.
- DOT 5.1: Even higher boiling point, best for high-performance cars.
Remember, DOT 5.1 is not the same as silicone-based DOT 5.
Check fluid color for clues on condition and type. Fresh DOT 3 and DOT 4 look clear or light amber. Dark fluid could mean contamination or moisture, which can affect braking.
Look at the brake fluid's color often to make sure it's in good shape. Always follow your Nissan owner's manual for exact brake fluid needs and ask a mechanic if you're unsure about which one to use.
Prepare Vehicle for Maintenance
Before starting to flush and refill the brake fluid in your Nissan, make sure the car is ready. Park it on a flat surface to keep it steady. This helps with measuring the fluid accurately and stops the car from moving by accident. Use the parking brake fully and put wheel chocks behind the back wheels. This keeps the car stable and reduces the chance of it rolling.
Lift the hood and find the brake fluid container. Wipe the area around the cap clean. This keeps dirt and other stuff out of the system. Wear safety goggles and gloves to protect yourself from any fluid splashes.
Gather all the tools and materials you need, like a jack and jack stands, before you begin. These will help if you need more space under the car.
Check your car's manual for specific details about working with brake fluid. Different car models may need special steps. Getting everything ready helps you work safely and makes the brake fluid change go smoothly.
Drain Old Brake Fluid
Find the brake bleeder valve on your Nissan. It's usually on the brake calipers or wheel cylinders. The valve lets old brake fluid out. Make sure your car is lifted safely on jack stands so you can reach the brakes.
To start, connect a clear hose to the bleeder valve. Put the other end of the hose into a container to catch the fluid. This way, you avoid spills. Use a wrench to slightly open the valve. Ask someone to press the brake pedal softly. This pushes the old fluid out through the hose.
Watch the fluid color. If it looks dark or cloudy, it means there are dirt or particles in it, and you need to flush it well.
Keep an eye on the brake fluid reservoir so it doesn't run empty. If it does, air can get into the system, which is bad for the brakes.
Once the fluid is out from a wheel, close the valve tightly before going to the next one. Following these steps will help keep your brake system working well.
Refill With New Brake Fluid
To refill your Nissan's brake system with new fluid, first check your owner's manual for the right type of brake fluid. Different fluids like DOT 3 or DOT 4 have unique properties, and using the wrong one can harm your brakes.
Find the master cylinder reservoir, which is usually near the back of the engine space. Clean the cap and area around it to keep dirt out. Fill the reservoir with fresh brake fluid until it reaches the maximum mark. Do not overfill to avoid spills.
Change the brake fluid every two years or after 24,000 miles, based on how you drive and the weather. This helps keep the fluid working well and stops moisture and rust.
Dispose of old brake fluid according to local rules.
Test the Brake System
Check the brake system after adding brake fluid. First, look at the brake lines, hoses, and calipers. Make sure they aren't leaking or damaged. Check that the brake fluid reservoir is filled to the right level.
Next, test the brakes. Start the car and let it idle. Press the brake pedal hard. It should feel firm, not soft or spongy. If it feels soft, there might be air in the system or not enough fluid. This needs checking.
Take the car for a short drive in a safe place. Use the brakes at different speeds. See how well they work. Listen for any strange noises like squealing or grinding. These noises may mean something is wrong and needs fixing.
Doing these checks helps ensure the brakes are working properly.
