Avid car enthusiasts know the dangers of running low on your brake fluid. Braking may begin to feel bouncy or soft, and you won’t decelerate immediately. Your brakes will also begin to squeak when your foot hits the pedal.
One way to get ahead of any problems is by checking your brake fluid color. The color of that fluid can tell you a lot about how well your vehicle is running. Additionally, any changes in the color may suggest that you need fresh brake fluid in your car.
Here’s your guide to brake fluid color and what it means.
What Color is Brake Fluid?
First of all, vehicle owners should know what color their brake fluid is supposed to be. This all depends on the type you’ve purchased and what your vehicle needs.
The two main types are DOT 3 and DOT 4. DOT 3 breaks down faster and needs to be changed more often than DOT 4.
You can expect DOT 3 brake fluid to appear in faint colors of anything ranging from yellow to blue. DOT 4 fluid is mostly clear but can have a tinge of yellow or red.
DOT 5 and DOT 5.1 fluids are available for classic cars. The former looks purple, while the latter is either yellow, blue, or clear.
What Affects Brake Fluid Color
Yellow brake fluid is normal, but it may degrade and change color if exposed to too much moisture, high temperatures, and contamination with dirt and other debris.
Brown brake fluid is often due to aging or contamination. Oxidization due to exposure to high temperatures will cause it to darken.
You may also want to pay attention to the consistency of your brake fluid. Oily brake fluid suggests that it has come into contact with other types of fluid, such as engine oil or transmission fluid.
Why You Should Replace Old Brake Fluid
Brake fluid helps your entire braking system work. If it goes bad, you can expect reduced braking efficiency and component wear and tear. At worst, you’ll develop leaks and have system failures.
Vehicle owners can check their brake fluid themselves and add some if needed. However, fluid replacement will require a professional.
When to Contact a Mechanic
If your fluid levels are low, you can add some more braking fluid. You only need to take your car to a mechanic if the fluid has changed color or consistency or if you’ve noticed that you’re leaking oil.
The same rule applies if your dashboard warning lights turn on or if you hear unusual sounds that aren’t solved by adding more fluid. An ASE-certified mechanic can help solve your issues.
Don’t Put Off Vehicle Maintenance
Brake fluid color can easily go unnoticed if people don’t take the time to check it when they fill up their vehicle. That color can shine a light on if your car has developed certain problems, such as leaks or contamination.
