Perhaps the most essential part of your brake system is the master cylinder. This component is responsible for compressing fluid and directing it to each corner of your vehicle for fast effective stopping. Internal seals in your Mercedes GL-Class master cylinder can wear out over time causing a soft brake pedal or even total brake failure. If you suspect you have a faulty unit it is best to step up to a brand new Mercedes GL-Class master cylinder. Here at Andy's Auto Sport we have a full selection of Mercedes GL-Class master cylinders for you to choose from. With many models from all of the top brands you are sure to find the perfect master cylinder for your needs in our extensive collection.

In the early days of automobiles brake systems were 100% mechanical. They relied on either cables or push rods to operate the brakes. These systems proved inadequate and dangerous and lead to the invention of hydraulic brakes. Utilizing a master cylinder, hydraulic brake setups allowed the driver to deliver tremendous brake pressure with relatively little pedal effort, which drastically reduced stopping distances. While a standard master cylinder may be perfect for your application, if you want a little added flash there are also flashier chrome and stainless steel units that will give your engine bay an extra custom touch.

Q: What is a brake master cylinder? Why buy one?
A: Brake master cylinders are the components that take the mechanical force of your foot stepping on the brake pedal and convert it into hydraulic pressure which physically operates your brakes and causes your car to stop. Over time dirty brake fluid can cause the seals inside of your master cylinder to wear out. This can have varying results from a slow leak in the system to a complete loss of brake pressure. Losing your brakes is one of the most dangerous failures that can occur on your vehicle. Do not gamble with your own safety. Affordable replacement cylinders are available that will have your car stopping like new again. In addition master cylinders are offered with different bore sizes which can give improved pedal feel when used with the appropriate brake setup. Numerous finishes are also available to add a custom touch to your engine bay.
