Can You Add Brake Fluid While Car is Running?

Is it Safe to Add Brake Fluid While the Car is Running?

Adding brake fluid while the car is running is not recommended. The reason is that when the car is running, the brake system is under pressure, and opening the brake fluid reservoir can lead to air entering the system. Air in the brake system can cause a spongy feeling in the brake pedal and reduce the effectiveness of the brakes. Therefore, it’s best to add brake fluid when the car is turned off.

It’s also important to note that adding too much brake fluid can have adverse effects. Overfilling the brake fluid reservoir can cause the fluid to overflow and damage other components in the engine compartment. Therefore, it’s crucial to add brake fluid to the recommended level only.

How to Add Brake Fluid to Your Car

Adding brake fluid to your car is a quick and straightforward process. Here’s a step-by-step guide:

  1. Locate the brake fluid reservoir under the hood of your car. It’s typically located on the driver’s side of the engine compartment and is marked with a cap that says “brake fluid.”
  2. Clean the brake fluid reservoir and the surrounding area to prevent dirt and debris from contaminating the brake fluid.
  3. Remove the cap from the brake fluid reservoir.
  4. Check the brake fluid level. The level should be between the “minimum” and “maximum” marks on the reservoir. If the level is low, add brake fluid to the recommended level.
  5. Replace the cap and tighten it securely.
  6. Start the engine and pump the brakes a few times to ensure that the brake fluid is distributed evenly throughout the system.

The Benefits of Regularly Checking Your Brake Fluid

Regularly checking your car’s brake fluid level is crucial to ensure that your brakes are working correctly. Here are some benefits of doing so:

  1. Improved safety: Maintaining the recommended brake fluid level ensures that your brakes are working correctly, which enhances your safety while driving.

  3. Longevity of brakes: Regularly checking and adding brake fluid can help prolong the life of your brakes and prevent costly replacements.

Brake Fluid vs. Power Steering Fluid

It’s essential to note that brake fluid is not interchangeable with power steering fluid. Although the two fluids may look similar, they have different compositions and functions in the car. Mixing the two fluids can cause damage to the brake system, leading to expensive repairs. Therefore, it’s crucial to use the recommended fluid for each system.

In conclusion, adding brake fluid while the car is running is not recommended as it can cause air to enter the brake system. It’s essential to add brake fluid to the recommended level only and ensure that the brake fluid reservoir is clean. Regularly checking your brake fluid level can help improve safety, save you money on repairs, and prolong the life of your brakes. Always use the recommended fluid for each system and avoid mixing brake fluid with power steering fluid.
