Easy Guide to Brake Fluid Change

Brake Fluid Change

To keep your vehicle safe. It’s important to pay attention to a part that often gets forgotten – brake fluid.

Brake fluid change is important for your car’s brakes to work well. It helps transmit the force from the brake pedal to the brake callipers. Which then stops your vehicle by holding the brake rotors.

If you don’t take care of your brake fluid. It could lead to potential brake failure and put your safety at risk.

So, how often should brake fluid be changed?

Most experts agree it’s a good idea to do it every 2 years. But there are other factors to think about too.

Now let’s talk about why brake fluid is important, when, and how to change old fluid.

Why Is Brake Fluid Important?

Brake fluid plays a vital role in making your brakes work efficiently.

  • When you press the brake pedal. It helps transfer the movement and force needed to stop your vehicle.
  • Braking generates a lot of heat. Which can create moisture in the brake system. Brake fluid absorbs this moisture. Preventing it from causing problems like brake failure.
  • It also acts as a lubricant for moving parts and stops them from corroding. The fluid needs to stay liquid in all temperatures to do its job well.

Remember, adding brake fluid isn’t something you regularly do.

If your brake fluid is low. It could mean your brake pads are wearing out and need changing soon. A sudden drop in fluid signals a problem with your brakes. So, it’s a good idea to have brake fluid checked by a mechanic check them if you’re not sure.

4 Types of Brake Fluid

Brake fluid is important for your vehicle’s brakes to work well. It connects the brake pedal, brake line, and brake callipers. Making sure that force is transferred smoothly.

There are several types of brake fluid. The Department of Transportation (DOT) separates brake fluids into four types:

  1. DOT 3
  2. DOT 4
  3. DOT 5
  4. DOT 5.1

Each type has its boiling point and mix. Which makes it right for different types of vehicles.

Most cars use DOT 3, DOT 4, or DOT 5.1. They absorb moisture from the air.

DOT 5 is different. It doesn’t absorb moisture. And is often used in cars that stay parked for a long time. Like collector cars or military vehicles.

To keep your brake system working its best and ensure safety. It’s important to use brake fluid that meets your car-specific standards.

Brake Fluid has a High Boiling Point

When you brake. High temperatures (up to 204° to 260°C) hit the wheel cylinders and callipers. Despite the high heat, brake fluid must work well. Brake fluid has a high boiling point to withstand the heat generated during braking.

If brake fluid reaches its boiling point, it turns into vapour in the brake line. This makes the fluid compressible and unable to transfer braking force properly.

Why Change Brake Fluid Regularly?

Brake fluid is special because it doesn’t easily turn into vapour when things get hot. Which is great for braking.

But it has a downside.

  • It attracts moisture over time, making it less effective.
  • If moisture builds up in the brake fluid. It can make the brake pedal feel soft. And it can harm the brake system. Including the brake lines, master cylinder, and callipers.
  • If the brake fluid gets too hot. It can boil and mess up your brakes. Causing them to not work well. Brake failure is something you definitely want to avoid.

That’s why it’s important to change your brake fluid regularly.

Brake Fluid Facts: 7 Tips to Keep in Mind

  1. Only use DOT 3 or DOT 4 fluid in your car.
  2. Don’t use any other fluid instead of brake fluid.
  3. Wash your hands after touching the brake fluid.
  4. Never use DOT 5 fluid if your car uses DOT 3 or DOT 4.
  5. DOT 5 doesn’t mix well with glycol fluids in cars with ABS brakes.
  6. Avoid spilling brake fluid as it can harm painted surfaces and finishes.
  7. You can use DOT 4 in a car that uses DOT 3. But NOT the other way around.
