Just like we explored in Part 1, the fluids in your vehicle are its lifeblood, each serving a critical function to ensure your ride is smooth, efficient, and safe. We already delved into the roles of engine oil, transmission fluid, and coolant. Now, in this second part of our comprehensive guide, we’ll explore three more vital automotive fluids: brake fluid, power steering fluid, and windshield washer fluid. 

Brake Fluid 

The first fluid we’ll talk about today is brake fluid. You know how your heart pumps blood, which carries oxygen to your muscles so you can hit the brakes on that bicycle of yours? The same principle applies to your car – but instead of blood, it uses brake fluid. 

When you press the brake pedal, brake fluid transfers this force into pressure to the front and rear brakes, bringing your car to a safe, smooth stop. The ability to stop efficiently is a critical part of vehicle safety, which makes maintaining the right levels of brake fluid extremely important. 

Regular brake fluid checks are essential because brake fluid can degrade over time and become contaminated with water from the air, reducing its effectiveness. It’s also a good idea to flush and replace your brake fluid every two years or as recommended by your vehicle manufacturer. Remember, a well-maintained braking system can literally be a lifesaver. 

Power Steering Fluid 

Next up is power steering fluid. Imagine trying to turn the wheels of your car manually. Sounds like a Herculean task, doesn’t it? Thankfully, power steering fluid is here to save the day. 

Power steering fluid acts as a hydraulic fluid that transmits power in the steering system, allowing you to turn the wheels easily. If your power steering fluid is low or contaminated, you may notice that your steering wheel feels heavier than usual, making it more difficult to steer your vehicle. 

As with the other fluids we’ve discussed, regular checks and maintenance are crucial to prevent potential issues. Your vehicle’s manual should provide recommendations on when to change your power steering fluid, but a good rule of thumb is to check it every time you change your engine oil. 

Windshield Washer Fluid 

Finally, let’s talk about windshield washer fluid. While it may not contribute to the mechanical workings of your car, it plays an essential role in maintaining visibility while driving. 

Windshield washer fluid, as the name suggests, cleans the windshield. This is especially important in certain weather conditions where dust, insects, snow, or other debris may obscure your view. 

While windshield washer fluid doesn’t typically need to be replaced at set intervals like engine oil or brake fluid, it’s still important to keep the reservoir filled. A clean windshield can significantly improve your visibility and safety on the road. 


To wrap up, we’ve explored the functions of various automotive fluids including brake fluid, power steering fluid, and windshield washer fluid. From helping you stop safely, making steering a breeze, to keeping your windshield clean for optimal visibility, these fluids are integral to your car’s performance and your safety on the road. 

Just like the fluids in Part 1, the ones we’ve discussed today require regular checks and maintenance. So, get to know your vehicle’s needs, stay on top of those fluid levels, and remember – a well-maintained car is a happy car! And when your car’s happy, you’ll be, too.
