Brakes are an essential part of any vehicle, and their proper functioning is crucial for your safety on the road. One of the key components of a brake system is the brake fluid. It is responsible for transmitting the force from the brake pedal to the brake pads, which in turn stop the vehicle. Over time, brake fluid can become contaminated, and it is important to change it regularly to ensure optimal brake performance.

Why Change Your Brake Fluid?

Brake fluid naturally absorbs moisture from the air over time, which can cause it to become contaminated. This can lead to reduced brake performance, as moisture in the fluid can cause corrosion in the brake system. Additionally, high temperatures can cause the fluid to break down, reducing its effectiveness even further. Changing your brake fluid regularly will help ensure that your brakes are working as they should.

When Should You Change Your Brake Fluid?

Manufacturers typically recommend changing brake fluid every two years or 24,000 miles, whichever comes first. However, if you frequently drive in stop-and-go traffic or in mountainous areas, you may need to change your brake fluid more often. Additionally, if you notice any signs of brake fluid contamination, such as a spongy brake pedal or reduced braking performance, you should have your brake fluid changed immediately.

How to Change Your Brake Fluid

Changing your brake fluid is a relatively simple process that can be done at home with the right tools. Here are the steps involved: 1. Gather your tools: You will need a wrench, a turkey baster or syringe, a container to catch the old fluid, and a new bottle of brake fluid. 2. Locate the brake fluid reservoir: This is typically located on the driver’s side of the engine compartment. 3. Remove the old fluid: Use the turkey baster or syringe to remove as much of the old fluid as possible from the reservoir. 4. Refill the reservoir with new fluid: Pour the new fluid into the reservoir until it reaches the “full” line. 5. Bleed the brake system: Starting with the brake farthest from the reservoir, use a wrench to open the bleeder valve and allow the old fluid to drain out. Once the fluid runs clear, close the valve and move on to the next brake. Repeat this process until you have bled all four brakes. 6. Check the fluid level: After bleeding the brakes, check the fluid level in the reservoir and add more fluid if necessary.


Regular brake fluid changes are a vital part of car maintenance that can help ensure your brakes are working as they should. By following the steps outlined above, you can change your brake fluid at home and keep your vehicle safe on the road. Remember to check your owner’s manual for specific recommendations on when to change your brake fluid, and don’t hesitate to seek professional help if you are unsure about the process.
