Brake Fluid: Why should you change it regularly?

Brake fluid is an integral part of your car’s braking system. It transmits hydraulic pressure from the brake pedal to the calipers that push the brake pads. Eventually, brake fluid gets dirty or degrades. If brake fluid change is not done frequently, the performance and effectiveness of brakes in your vehicle can suffer.

How Brake Fluid Functions in Your Car?

Brake fluid works in a hydraulic system. In effect, whenever you step on the brake pedal, you have created some hydraulic pressure that forces the brake fluid through tubes and pipes to the calipers where it squeezes the brake pads against the rotors and brings the car to a halt.

Why You Must Change Brake Fluid

Over time, brake fluid absorbs moisture and becomes less effective. This leads to poor performance, internal corrosion, and brake failure. Here’s what regular brake fluid replacement prevents:

• Moisture buildup that weakens pressure
  

• Degraded fluid that increases stopping distance
  

• Corrosion of brake components
  

• Brake system failure in emergencies
  

• Voiding of manufacturer warranties
  
  

Ignoring this simple service can lead to expensive repairs — or worse, a dangerous accident.

Signs of Low Brake Fluid

The following are several indications of low brake fluid:

• Soft or spongy brake pedal: A pedale being characteristically soft indicates that there are low fluid levels.
• Squeaking or squealing brakes: The sound, although most produced as a result of brake pad wear, can also indicate low brake fluid.
• Brake warning light: If you notice that the dashboard brake warning light is on, then this indicates trouble, which can, among other things, present itself in the form of low brake fluid.
• Leaking brake fluid: Obvious leak points around brake system components signify fluid loss.

Warning Signs of Low or Bad Brake Fluid

If you notice any of the following, it’s time to schedule a brake inspection:

• Soft or spongy brake pedal
  
• Brake warning light on your dashboard
  
• Squeaking or squealing during braking
  
• Leaking brake fluid under the car
  
• Increased stopping distance or delayed brake response
  

Don’t wait for a minor sign to become a major problem.

What Happens If You Keep Driving Without Enough Brake Fluid?

Driving with low or degraded brake fluid is extremely dangerous. Without enough fluid, your brakes may not respond at all. This can result in total brake failure — putting you, your passengers, and others on the road at serious risk.

Types of Brake Fluid

3. Refill with fresh, high-quality brake fluid
   
   
4. Bleed the system to remove air bubbles
   
   
5. Inspect all brake components for leaks or damage

How Often Should You Change Brake Fluid?

Most manufacturers recommend changing brake fluid every 2 to 3 years or 30,000 to 50,000 miles, depending on driving habits. If you’re in frequent stop-and-go traffic or drive a high-performance vehicle, you may need it done more often.
