How to Flush Brake Fluid
Your vehicle uses tons of different fluids to run smoothly and safely on the roads of Westwood, Dedham, Needham, and Norwood, Massachusetts. One of them is brake fluid, helping all the moving parts of this vital system move seamlessly—but just like other fluids in your ride, it must be changed.
Whether you do it yourself or have it done professionally, brake fluid needs to be switched out around every 30,000 miles. In this guide, the team at the Mercedes-Benz of Westwood Service Center will go over how to flush brake fluid and why it’s essential, so you can stay steady behind the wheel.
What Is Brake Fluid?
Did you know that every time you bring your vehicle to a stop, your braking system utilizes brake fluid? In fact, without this essential substance, your brakes won’t work. What exactly does brake fluid do, though?
In order for your brakes to have enough stopping power when you press on that pedal, brake fluid is needed. It takes the force from the pedal, turns it into pressure, and sends it to the front and back brakes, allowing the vehicle to stop.
However, if there isn’t enough brake fluid, or if the brake fluid has become too dirty, it can’t do its job correctly. This is when a brake fluid flush is needed.

How to Flush Your Car’s Brake Fluid
A brake fluid flush is needed when the fluid has become too contaminated or when new brake components are installed. This provides a better overall brake performance!
While this service can be done at home, it’s best to have it performed by a professional to reduce the risk of possible damage.
When you bring your vehicle to our industry-leading service center, our certified technicians will do the following…
- Empty the master cylinder: Our technicians will start by removing all the fluid that’s currently in your vehicle’s master cylinder reservoir. They use a special pump that ensures all the liquid is completely drained.
- Fill with new brake fluid: Next, our team will fill the reservoir with fresh, clean brake fluid. This gives your vehicle the hydraulic fluid it needs to provide stopping power while on the road.
- Bleed the brakes: With the new brake fluid, the technicians will bleed the brakes to ensure no bubbles are in the brake lines. Starting in the back of the vehicle, they’ll bleed out the back two calipers and wheel cylinders. They’ll then move to the front, re-checking the master cylinder reservoir along the way.
- Perform a final top-off: After the brakes are bled, our techs will fill the reservoir with more brake fluid until it reaches the “fill” line.
