Safe system for reliable braking performance

The brake fluid reservoir is a central component in the brake system: it continuously supplies the brake master cylinder and wheel brake cylinder with brake fluid and compensates for fluctuations in the fill level. Defective seals, leaking connections or faulty sensors can impair braking performance or lead to failures.

Suitable spare parts for your brake circuit

In our store you will find expansion reservoirs in various designs, seal kits and cable repair kits for brake fluid reservoir sensors. These components are specifically designed for brake systems and enable maintenance, repair or replacement with high precision and reliability.

Brake fluid reservoir

What should you look out for when buying:

COMPATIBLE DESIGN AND CONNECTION

The reservoir must fit your brake system exactly, both in terms of shape and the number and size of the connections.

GASKET SET QUALITY

A high-quality seal set prevents leaks and ensures long-term tightness even under pressure and temperature changes.

SENSOR AND WIRING REQUIREMENTS

If your system has a level sensor, check whether the cable repair kit is included in the range and fits the existing connector geometry.

Expert Guide: Everything You Need to Know About Brake Fluid Reservoirs & Parts

The reservoir (expansion tank) continuously supplies the master cylinder and wheel cylinders with brake fluid and compensates for fluctuations in fluid level—such as those caused by pad wear or temperature changes. It is therefore a key component for consistent, reliable braking performance.

The system includes the expansion tank itself, the cap, gaskets, and—if present—the brake fluid level sensor with its associated wiring. Suitable gasket kits and wiring repair kits are available for maintenance and repair.

Typical signs include a dropping fluid level, visible leaks or damp spots on the reservoir and at the connections, a brake warning light coming on, and a fluid level sensor that no longer triggers reliably. Since this is a safety-critical component, such symptoms should be checked immediately.

The reservoir must match the brake system exactly in terms of shape, as well as the number and size of the connections. Only then can it be installed securely and without leaks. A different design will result in leaks and jeopardize the function of the entire brake system.

A high-quality seal kit prevents leaks and remains permanently airtight even under pressure and during temperature fluctuations. If your system has a level sensor, check to see if a compatible cable repair kit is available and fits the existing connector configuration.

We carry expansion tanks in various designs, as well as seal kits and cable repair kits for brake fluid level sensors for all major commercial vehicle brands, such as MAN, Mercedes-Benz, Scania, Volvo, DAF, and Iveco.
