Here's what Will Happen If You’re Mercedes' Brake Fluid Level Falls Too Low

If the brake fluid level in your Mercedes drops below the recommended level, it will take longer to stop than usual. That's because the brake system won't be able to function as well as it should if there isn't enough hydraulic fluid. In addition to bad braking efficiency, a declining brake fluid level is often accompanied by a few other telltale symptoms.

In this blog post, we will go through some of the most common causes and symptoms of a drop in brake fluid level in a car. Plus, you will learn the consequences of driving a vehicle with a low brake fluid level.

What Can Cause Mercedes’ Brake Fluid Level to Drop?

It is dangerous to operate a car that’s running low on brake fluid. Therefore, it is best to know the reasons ahead of time so you’ll know how to avoid major braking system issues or when to call a mechanic. So, what exactly can cause a Mercedes’ brake fluid level to drop?

Well, a leak in the system typically causes the brake fluid level in a vehicle to drop. Whether the leak is in the master cylinder, brake lines, hoses, or any other parts- if left unaddressed- can make the braking system of the vehicle inefficient. So, if you notice a drop in brake fluid level in your Mercedes, look for the pinhole from where the fluid is leaking out. If you are unable to locate the leak's source, consult a mechanic right away.

Signs Your Mercedes’ Brake Fluid Level Is Declining

A brake fluid leak in a car is often easy to notice- if you know where to look. If there is a leak in your Mercedes braking system, you might experience one of the following signs.

1- Liquid dripping from car

If you notice a light yellow-colored fluid dripping from your Mercedes, it's probably from the braking system. The fluid that is dripping from your vehicle may also be transmission fluid, motor oil or windshield wiper fluid. In any case, you need to find out where the fluid is leaking from and take analogous actions. The pinhole responsible for the dripping of brake fluid should be identified and fixed as early as possible.

2- Dashboard warning lights

That’s right… brake fluid level, if drops below the recommended level, will prompt the onboard diagnostic system to alert the driver by activating different types of dashboard warning lights such as brake and ABS warning lights. So, if you are seeing any of these warning lights while driving your Mercedes, check the brake fluid level and if it is on the decline, find out the reason behind it. Just so you know, numerous other things can trigger those warning lights.

3- Spongy brake pedals

A good way to tell if your car is low on brake fluid is to depress the brake pedal to see how hard/soft it is. If it feels spongy… the cause could be a declining brake fluid level. Brake pads with thin friction materials can also result in such a problem. Whatever the cause may be driving with spongy brakes is not safe. Find out what's wrong with the braking system of your car as soon as possible.

Consequences of Driving a Car with Low Brake Fluid

Increased stopping distance

The brake fluid is something that we often take for granted. But, it is the lifeblood of a vehicle's braking system. It essentially transmits force applied on brake pedals to brake pads. In the event that the brake fluid level in a car drops below the recommended level, its stopping distance will increase. Some other factors that can increase the stopping distance of a vehicle are brake pads with thin friction material, air bubbles in brake lines, etc.

It is unsafe

It is simply not safe to drive a vehicle that’s low on brake fluid. Check your vehicle’s brake fluid quality and quantity from time to time and if necessary replace or replenish it.

To Put It In A Nutshell…

A sufficient amount of brake fluid is required for a vehicle's braking system to function. So, keep an eye on your Mercedes’ brake fluid level. If you suspect a leak in your vehicle’s braking system, take it to a nearby car repair center to have the braking system serviced.
