The brakes of your vehicle are one of the most critical safety components, and maintaining them in good condition is essential to ensure a safe and smooth ride. One of the most important aspects of brake maintenance is checking the brake fluid level and its appearance. Brake fluid is a hydraulic fluid that transfers pressure from the brake pedal to the brake calipers, causing the brake pads to clamp onto the rotors and slow down or stop the vehicle. Over time, brake fluid can become contaminated with debris, moisture, and other impurities, which can affect its performance and the overall braking system. In this article, we will explore what brake fluid should look like and how to check it.
What is Brake Fluid?
Brake fluid is a specialized hydraulic fluid designed to withstand the high pressures and temperatures involved in the braking process. It is typically a mixture of glycols, such as ethylene glycol or propylene glycol, and other additives that provide lubrication, corrosion protection, and rust inhibition. Brake fluid is usually colorless, odorless, and has a sweet or slightly bitter taste. It is also non-toxic and non-flammable.
Why is Brake Fluid Important?
Brake fluid plays a critical role in the braking system, and its importance cannot be overstated. Here are some reasons why brake fluid is so important:
- It transfers pressure from the brake pedal to the brake calipers, allowing the brake pads to clamp onto the rotors and slow down or stop the vehicle.
- It lubricates the brake system, reducing friction and wear on the brake components.
- It provides corrosion protection to the brake system, preventing rust and corrosion from forming.
- It helps to maintain the brake system’s hydraulic pressure, ensuring that the brakes function properly.
What Should Brake Fluid Look Like?
Brake fluid should be a clear or slightly yellowish liquid. If it is cloudy, dirty, or has a strange color, it may be contaminated or degraded. Here are some signs that brake fluid may be contaminated or degraded:
- Cloudiness or haziness
- Strange color, such as brown, green, or black
- Sludge or sediment at the bottom of the reservoir
- Foul odor or taste
If you notice any of these signs, it is essential to have the brake fluid changed as soon as possible. Contaminated or degraded brake fluid can cause a range of problems, including: (See Also: Can I Use Any Brake Fluid For My Car? – The Truth Revealed)

How to Check Brake Fluid
Checking brake fluid is a relatively simple process that can be done at home or at a repair shop. Here’s how to do it:
- Locate the brake fluid reservoir: The brake fluid reservoir is usually located under the hood of the vehicle, near the brake master cylinder. It may be labeled “Brake Fluid” or have a picture of a brake fluid canister.
- Check the fluid level: The brake fluid level should be at or near the “MIN” mark on the side of the reservoir. If the level is low, you may need to add brake fluid.
- Check the fluid color: As mentioned earlier, brake fluid should be a clear or slightly yellowish liquid. If it is cloudy, dirty, or has a strange color, it may be contaminated or degraded.
- Check for signs of contamination: Look for signs of contamination, such as sludge or sediment at the bottom of the reservoir, or a foul odor or taste.
How to Change Brake Fluid
Changing brake fluid is a relatively simple process that can be done at home or at a repair shop. Here’s how to do it:
- Locate the brake fluid reservoir: The brake fluid reservoir is usually located under the hood of the vehicle, near the brake master cylinder. It may be labeled “Brake Fluid” or have a picture of a brake fluid canister.
- Drain the old brake fluid: Use a brake fluid drain pan to catch the old brake fluid as you drain it from the reservoir. Be careful not to spill any of the old fluid on the ground or on your skin.
- Add new brake fluid: Use a brake fluid that meets the manufacturer’s specifications. Add the new brake fluid to the reservoir, making sure not to overfill it.
- Replace the reservoir cap: Once the new brake fluid is in the reservoir, replace the cap and make sure it is tightened securely.
Conclusion
Brake fluid is a critical component of the braking system, and its appearance can indicate its condition and performance. By checking the brake fluid level, color, and signs of contamination, you can ensure that your brakes are functioning properly and safely. If you notice any signs of contamination or degradation, it is essential to have the brake fluid changed as soon as possible. Remember to always use the correct type of brake fluid for your vehicle and to follow the manufacturer’s guidelines for maintenance and repair.

FAQs
What happens if I don’t change my brake fluid?
If you don’t change your brake fluid, it can lead to a range of problems, including brake failure, reduced braking performance, and corrosion in the brake system. It is essential to change your brake fluid regularly to ensure the safety and performance of your vehicle.
Can I use any type of brake fluid?
No, you should only use brake fluid that meets the manufacturer’s specifications. Using the wrong type of brake fluid can cause damage to the brake system and affect its performance.
How often should I change my brake fluid?
The frequency of brake fluid changes depends on the manufacturer’s recommendations and the vehicle’s usage. Typically, brake fluid should be changed every 30,000 to 50,000 miles, but it’s best to consult your owner’s manual or a repair shop for specific guidance.
What are the signs of brake fluid contamination?
The signs of brake fluid contamination include cloudiness, strange color, sludge or sediment at the bottom of the reservoir, and a foul odor or taste. If you notice any of these signs, it’s essential to have the brake fluid changed as soon as possible. (See Also: Which Brake Pads Produce Less Dust? – Top Picks Revealed)
Can I check my brake fluid level myself?
Yes, you can check your brake fluid level yourself. Locate the brake fluid reservoir under the hood of your vehicle, and check the level against the “MIN” mark on the side of the reservoir. If the level is low, you may need to add brake fluid.
