Brake fluid is a liquid used in cars to help stop the wheels when you step on the brake pedal.

It helps reduce how much force goes through your car’s brakes, which reduces wear and tear over time.

Brake fluid also helps keep dust and other particles out of your brake system.

This article discusses what brake fluid does, why it’s important to change it regularly and provides instructions for changing your own brake fluid!

We have described the functions of the brake fluid here in this article in brief detail.

What is brake fluid

Brake fluid is used to prevent the metals inside components like calipers, wheel cylinders, master cylinders, and ABS control valves from corrosion. Moisture must also be protected against.

Additives (corrosion inhibitors) are added to the original brake fluid to assist with this.

Brake fluid is the liquid that is used to provide hydraulic pressure to the brake system of a car or any vehicle.

Working mechanism of fluid brakes

When you step on the brakes of vehicles, brake fluid is forced through lines and pushed into calipers.

Brake fluid also helps keep dust and other particles out of your brake system.

The working mechanism of a liquid type brake system is as follows:

Brake fluid comes out of the master cylinder and fills the lines connected to wheel cylinders with pistons inside. When these pistons move into place, they press against the brake pads attached to the wheels.

This causes resistance on your car’s brakes, so you can slow down or stop if necessary. The brake fluid works as a lubricant to keep the brake system from grinding or squeaking.

When you step on the brakes, your car’s pressure-sensitive brake sensor detects this and sends an electrical impulse that travels along flexible metal lines (also called hardlines) until it reaches the ABS control unit.

The information is then examined and sent back to each wheel so it can be acted upon.

Here’s a step-by-step guide on how brake fluid works in a hydraulic braking system

  • The motorist applies the brake pedal.
  • The brake caliper is compressed by a pedal inside.
  • The brake fluid is pushed from inside the lines to outside through this compression, raising the pressure within the brake lines and causing them to move.
  • When the brake fluid is released, it forces the brake rotors to squeeze down on the brakes. The connection between the brake pads and the wheels causes them to slow and eventually stop the wheels’ rotation and the vehicle itself.

There are two types of brake fluids – petroleum-based and silicone-based

The two types of brake fluids or liquids are:

Petroleum-based brake fluid is usually dark red in color, while silicone-based brake fluid is noticeably pink.

Additionally, petroleum-based fluids have a much higher boiling point than their alternative – making them more suitable for extreme weather conditions.

Silicone-based brake

fluid is biodegradable, making it environmentally friendly and decreasing the chance of spilling on your garage floor.

However, you should never use silicone-based fluids in place of petroleum-based fluids or vice versa because each type has its own high boiling point with different ranges.

Silicone-based brake fluids are better for stopping on these types of surfaces because they have higher boiling points than petroleum-based liquids.

Aerospace and aircraft operators use silicone-based fluids as a standard operating procedure because it does not break down or freeze at extremely low temperatures.

Additionally, if your car breaks down on an icy road at night time with no lights, the brake fluids will not freeze.

Petroleum-based fluid

Is made of ingredients that are able to withstand high temperatures and resist water absorption – whereas silicone-based fluid comes with an extra safety feature because it’s biodegradable!

This makes it environmentally friendly and safe for use in all conditions.

However, you should never switch the two types of brake fluid because each type has its own high boiling point (the petroleum-based fluid’s boiling point is roughly 400 degrees Fahrenheit, while the silicone-based brake fluid has a much higher boiling point at 1000 degrees).

Petroleum-based brake fluids can be found in most cars, but they may not be as effective on some surfaces like asphalt.

WHEN BRAKE FLUID IS LOW

Any leaks or issues with the brake fluid may lead to a low fluid level. When the brake fluid of your vehicle is low, then you’ll notice:

  • Brake light with a built-in LED flashlight.
  • Reduced stopping capabilities
  • Brake pads are wearing faster than normal.

You need new brakes

Brake fluid is the lubricant that keeps your braking system running smoothly and quietly. It also helps keep dust and other particles out of the system.

When it’s time for you to change your brake pads, make sure you check your brake fluid level before buying new parts. You’ll save money by doing this, and it will help extend the life of your braking system!

FAQS

What happens when the brake fluid levels drop?

A low brake fluid level may cause the brake light to come on. Leaks in the system are significant since they provide little or no stopping power while driving.

A difficult-to-stop or mushy brake pedal is a telltale sign of low brake fluid. When you apply pressure on the brake pedal, it will feel spongy and soft.

Is it possible to drive without brake fluid?

It isn’t! Brake fluid is the intermediary “middleman” that connects your brake pedal to your brakes.

Your pedal pressure is transmitted through the brake lines’ fluid to the pads by the fluid. Your brakes will not function without this fluid.

How long does brake fluid last?

If kept in excellent condition, your brake fluid will last approximately two years after being unopened.

Only the amount of fluid required for your car should be purchased since it deteriorates in quality as soon as it is opened.

Is low brake fluid considered an emergency?

Your car’s brakes allow you to stop safely, especially in emergency situations.

If your Brake Warning Light comes on, you should pay attention and contact your mechanic right away.

Your brake fluid level might be low at times, which means it must be refilled or new fluid supplied.
