If you are an owner of a Mercedes-Benz, it is important to know almost every inch of your vehicle. As you know, you are driving more than just a car, you are driving an experience. With that said, Mercedes-Benz has gone above and beyond to make sure that their cars drive and operate at optimal levels. This means having intricate and high-efficiency components inside the engine of the car. One of the most important aspects is the brake system within a Mercedes-Benz vehicle. These systems consist of interconnected components that help operate the system with precision over a wide range of operating temperatures and weather conditions.

As mentioned in our previous blog brake fluid helps operate the brake pads during transportation and can absorb moisture, air, and dirt. If not tended to, the moisture can create corrosion within the internal rake components and decrease the boiling point of the brake fluid. This can cause the brakes to not function at optimal levels, which can be a dangerous risk while operating the vehicle.

When Should I Get My Mercedes-Benz Brake Fluid Changed?

While most cars tend to have recommendations of 36 months or 24,000 miles, for Mercedes-Benz we recommend every two years or 20,000 miles to be on the safe side. The procedure for changing the brake fluid on your Mercedes-Benz is a little different than most cars. Be sure to contact a trained technician as they use approved pressure bleeding machines and “DOT 4 plus” brake fluid. Since the brake system is known for its precision, the machines these technicians use are designed to properly flush out old fluid while not harming the any of the precision braking parts. The machine also ensures that the new brake fluid enters the system with no moisture or air.

It is important to have Mercedes-Benz approved parts and fluids being used when getting your car worked on. This is what Boston Motor Werks takes pride in as we are trained technicians with a passion for BMW, Porsche, and of course Mercedes vehicles, ensure that each customer leaves happy.

What Is A Brake System Flush?

It is well known that brake fluid is a very important aspect of your car’s daily operation. As you press down on the brake pedal, the fluid causes the brake pads to press against the rotors to slow your car down to a complete stop.  Over time, just like with transmission lines, the brake fluid will start to absorb air, moisture, sludge, dirt and other contaminants as you drive your car days on end. No matter if you drive a Mercedes, Porsche, or BMW your car will need to have a brake system flush at some point in the cars life cycle to keep the brakes working at optimal levels.

What Does a Brake Flush Consist Of?

A brake system flush for Mercedes, Porsche, or BMW vehicles includes removing the existing fluid and moisture out of the system. It is the replaced with new, clean, contaminant-free fluid. By having a brake flush performed on your car, you are ultimately ensuring proper performance of your brake system so there are no issues while driving and it also increases the lifespan of the system.

Brake System Flush Steps

  • Remove contaminated brake fluid.
  • Add new brake fluid.
  • Bleed the brakes.
  • Clean any surfaces where brake fluid has spilled during the bleeding process.
  • Check for fluid leaks.
  • Inspect brake pads, rotors, and hoses.
  • Test drive car with new fluid.

When Should I Get A Brake System Flush?

As each car is different, you will want to refer to the manufacturer’s manual for maintenance guidelines for fluid maintenance. However, common and good practice is getting your car checked for a brake fluid flush every 36 months or 24,000 miles. It is always good practice to have this service done by a trained professional as they will use the correct fluid for your car.

4 Warning Signs You Need To Get Your Brakes Replaced

Brakes are one of the most important aspects of your vehicle whether you have a BMW Porsche, or Mercedes or any other type of car. This is because these devices keep you safe as well as preventing the car from driving through unwanted places or things. When it comes to brakes, the only sure fire way to know if you need new brakes is if you take your care for a scheduled inspection and get results back saying you need a replacement. There are other factors to look out for while driving that are actually warning signs that you need new brakes.

Here are some signs of brake problems to look out for. If you experience any of these you should visit your repair shop or see a specialist as soon as possible.

Reduced Responsiveness or Fading

If your brakes are not responding as they normally would and should then this could be taken as an indication of a leak in the braking system. Another sign of a leak is if the pedal sinks towards the floor of your car. The type of leak could be either air or brake fluid but both require an inspection. The oldest way to figure out if your brake fluid is leaking is if you notice a small puddle of fluid when your car is parked.


If you are braking and your car starts to pull to one side it may be a sign that the brake linings are wearing unevenly. Another cause of this pulling motion is if there is some sort of foreign matter in the brake fluid. If either of these reasons are causing any pulling while you brake then you may need a brake adjustment or to have your fluids drained and replaced.

Grinding or Growling

If you start hearing a grinding or growling sound while you apply brakes to your car then your brake pads have been worn down completely beyond replacement. This noise is caused when the two metal pieces of the brake rubbing together. The longer you drive with worn down brake pads, the more likely you are to “score” or scratch your rotors and creating an uneven surface. Once the rotors are uneven, you will need to have them “turned” by a professional or replaced depending on the damage.


If you are driving, applying the brakes and notice a vibration or pulsating brake pedal then it is a sign your have warped rotors. Not to be confused from vibration when your vehicle is our of alignment, if the vibration occurs during braking situations when the anti-lock brakes are not engaged then it is a sign of warped rotors. This vibration is felt because the brake pads are not able to grab the surface easily.

BMW Break Repair

Breaks are probably one of the most important part of your car; without proper brakes, you put yourself and others in danger. Here at Boston Motor Werks, we will inspect and repair brakes on  BMWs; we have worked and repaired on BMW models from the early 1980s all the way to the 2014 models.

We only use BMW parts, pads and rotors on all break repair services; there is simply no other part, that compares to the reliability, bite, noise suppression, and performance of original BMW pads and rotors.

The rotors we use are made from high quality steel and alloy, and resist brake warping, scoring, and rust. Generic or aftermarket products don’t last as long, they are poorer quality, and they will actually cost you more money in the long run because you’ll have to repair them more frequently!
