Buy brake fluid online – Safety for your vehicle

Whether you need brake fluid for a regular change, for upcoming maintenance or as a replacement: the range covers the common DOT specifications as well as products for different vehicle types and applications. This way you can quickly find the right brake fluid for your car or motorcycle – conveniently from home. High-performance products for sporty driving and motorsport use are also available.

Brake fluid by DOT class

For older vehicles, DOT 3 or DOT 4 is often suitable, while modern vehicles with ABS and ESP frequently require DOT 4 or DOT 5.1. The DOT class indicates the dry boiling point and viscosity of the brake fluid. In motorsport and under heavy loads, special high-performance brake fluids with a particularly high boiling point are used, which ensure consistent braking performance even under extreme conditions.

Changing brake fluid – Maintenance & care

Brake fluid is hygroscopic and absorbs moisture over time, which lowers the boiling point and can impair braking performance. A regular change in accordance with manufacturer specifications contributes to the safety and longevity of the braking system. Choosing the right brake fluid and observing the appropriate change intervals helps to avoid expensive repairs and keep the braking system in perfect condition.

Who is this category suitable for?

The category is ideal for vehicle owners, DIY mechanics and workshops in Switzerland who need brake fluid for a scheduled change, for maintenance work or for complete refilling after a repair. At the same time, motorsport enthusiasts and drivers of high-performance vehicles will find special high-performance products that are often difficult to obtain in local retail stores.

Quality, safety & selection

When buying brake fluid, it is worth paying attention to the correct DOT specification, the vehicle manufacturer approvals and a high dry as well as wet boiling point – this ensures the braking system works reliably even under heavy loads. High-quality brake fluid also protects against corrosion and vapour bubble formation in the hydraulic system.

Frequently asked questions

What is brake fluid and what is it needed for?▾

Brake fluid is a hydraulic fluid that transfers pressure from the brake pedal to the brake pads. It ensures that the braking system works reliably and precisely – an essential component for the driving safety of every vehicle.

What DOT classes are there and what do they mean?▾

The DOT class indicates the dry and wet boiling point of the brake fluid. Common classes are DOT 3, DOT 4 and DOT 5.1. The higher the DOT class, the higher the boiling point and the better the heat resistance – important under heavy braking loads.

How often should the brake fluid be changed?▾

Most vehicle manufacturers recommend a change every two years, as brake fluid absorbs moisture over time. A regular change maintains full braking performance and protects the braking system from corrosion.

How can I tell that the brake fluid needs to be changed?▾

Signs that a change is needed include a spongy brake pedal, longer braking distances or a dark discolouration of the fluid. The warning light in the cockpit or an excessively high water content in a test can also indicate this.

Can I mix brake fluids of different DOT classes?▾

As a general rule, only the DOT class approved by the vehicle manufacturer should be used. DOT 4 can be used in DOT 3 systems, and DOT 5.1 is miscible with DOT 3 and DOT 4. DOT 5, however, is silicone-based and must not be mixed with other classes.

Which brake fluid is the right one for my vehicle?▾

You can find the right brake fluid in your vehicle's owner's manual. The DOT specification and any manufacturer approvals are decisive. If in doubt, a look at the service booklet or consulting a specialist workshop will help.

What is the difference between DOT 4 and DOT 5.1?▾

DOT 5.1 has a higher dry boiling point and lower viscosity than DOT 4. This makes DOT 5.1 particularly suitable for vehicles with modern braking systems such as ESP and ABS, as well as for sporty driving with high braking loads.

How do I dispose of old brake fluid properly?▾

Old brake fluid does not belong in household waste or wastewater. It must be disposed of as hazardous waste at a municipal collection point, a workshop or a recycling centre. In Switzerland, proper disposal is required by law.
