MAN 81511306013 brake master cylinder

Description

The MAN 81511306013 is a brake master cylinder, a critical component of the braking system in commercial vehicles. It's responsible for converting the force applied to the brake pedal into hydraulic pressure, which then operates the brakes on all wheels. This master cylinder is designed for use in MAN trucks and buses, ensuring reliable and efficient braking performance. Its robust construction and precise engineering contribute to a consistently firm pedal feel and dependable stopping power, enhancing both safety and driver control. The dimensions of this cylinder are 60 x 95 x 250 mm.

Key Features & Benefits

This thing is really the heart of your braking system. Basically, when you push the brake pedal, you’re pushing on a piston inside the master cylinder. That piston then pushes brake fluid through the lines to the brakes at each wheel. It builds pressure, and that pressure is what actually clamps down on the rotors or drums to stop the car. It also holds the pressure in the lines when you’re sitting still, so you don’t lose your brake power. Some have one piston, some have two, depending on the vehicle. Think of it as the starting point for everything brake – related. It takes the force from your foot and multiplies it, sending it along to all four corners of the car. Without it working correctly, you simply won't be able to stop. It’s a pretty critical component, clearly. It's also usually mounted right up on the firewall, sort of hidden away.

Symptoms, Risks & Replacements

It's important because, well, it controls stopping. If the master cylinder fails, you’ll likely notice if you have a spongy brake pedal, or if it slowly sinks to the floor when you're holding it. Sometimes, you'll get a complete loss of brakes, which is obviously a big deal. It’s something you really don’t want to mess around with. A failing master cylinder acts like a shield slowly crumbling – you might have some braking ability at first, but it’ll steadily get worse. You can find replacements pretty easily, sites like Fixparts Online have a good selection. It’s one of those things that’s worth keeping an eye on and addressing immediately if you suspect an issue.
