BMW E90 F01 F02 F07 F10 F11 F12 Brake Servo Vacuum Pipe Hose Line N55 7575774

BMW E90 F01 F02 F07 F10 F11 F12 Brake Servo Vacuum Pipe Hose Line N55 is an original component from the Lines, hoses and pipes group, designed for the brake booster vacuum system in BMW vehicles equipped with the N55 engine. It enables stable transmission of vacuum to the brake servo, which translates into predictable brake pedal response and safe operation of the entire system.

Application and function in the braking system

The vacuum pipe for the brake servo in the N55 engine is responsible for transporting vacuum from the power unit to the brake servo. A properly selected and airtight component:

• ensures stable brake assistance across the full range of engine loads,
• reduces the risk of a drop in braking efficiency during rapid acceleration,
• minimizes the possibility of errors related to the vacuum system.

Thanks to the factory geometry of the pipe, the correct routing in the engine bay is maintained, which limits stress, friction against other components, and potential leaks.

Compatibility with BMW models

The pipe has been designed specifically for the N55 unit used in the BMW E90 series as well as the F01, F02, F07, F10, F11, and F12 models. This means that it:

• fits factory mounts and vacuum system ports,
• requires no modifications or length adjustments,
• maintains the original installation path in the engine bay.

Such fitment facilitates quick installation and maintains consistency with other components of the braking system and engine accessories.

Characteristics of the original BMW pipe

The original BMW vacuum pipe from this group is made of materials resistant to temperature and the vacuum generated by the N55 engine. The design of the pipe has been developed to:

• maintain proper rigidity while providing installation flexibility,
• reduce the risk of micro-cracks and delamination during long-term use,
• ensure a tight connection with the servo ports and the vacuum source.

As a result, the pipe can be used as a functional replacement for the factory-installed component in BMW vehicles from the listed series.

Condition, installation, and benefits of use

The item comes from disassembly and is offered as a used brake servo vacuum pipe, which allows for an economical repair of the braking system while maintaining the manufacturer's original specifications. Pipe replacement is recommended in the event of:

• a noticeable drop in brake assistance,
• suspected leaks in the vacuum system,
• visible mechanical damage or signs of material aging.

Selecting an original pipe from the same product group reduces the risk of fitment issues and helps maintain predictable operating parameters of the braking system.
