two years have passed since the last change
Most manufacturers prescribe a brake fluid change at regular intervals (usually two years) regardless of how "clean" the fluid looks — its protective properties lose their effect gradually and unnoticed.

Why it matters
Why does brake fluid need to be changed?
Brake fluid is hygroscopic — it gradually absorbs moisture from the air even through a closed system.
Water lowers the boiling point
At a water content of only around 3 % the boiling point drops so far that heavy or prolonged braking can create a vapour bubble in the system. The result is a soft, spongy brake pedal, or even loss of braking effect at the critical moment.
Water causes corrosion
Water in the fluid also corrodes the internal parts of the ABS/ESP unit, the wheel cylinders and the calipers — repairs to these components are among the most expensive on the whole vehicle.
Preventive vehicle maintenance
Preventive vehicle maintenance
Changing the brake fluid regularly at the recommended interval is one of the cheapest forms of prevention on the whole vehicle. We recommend combining it with a regular check of brake pad and disc thickness — together the two checks give a complete picture of the brake system condition.
Request an appointmentWhen to act
When is a brake fluid exchange recommended?
Based on our experience, we recommend an exchange in cases where:
the brake pedal is softer or travels further
At a water content of around 3 % the boiling point drops so far that heavy or prolonged braking can create a vapour bubble in the system — the result is a soft, "spongy" pedal, or even loss of braking effect at the critical moment.
the fluid is dark, cloudy or has a high water content
Water in the fluid corrodes the internal parts of the ABS/ESP unit, the wheel cylinders and the calipers — repairs to these components are among the most expensive on the whole vehicle.
Products used
ATE equipment and fluid used for the brake fluid exchange
ATE FB 5EV
An electric unit for filling, flushing and bleeding brake systems, suitable also for modern electronic systems (ABS/ESP). It generates a pulsating flow of fluid for better flushing and bleeding, with adjustable working pressure up to 2.0 bar. Automatic shut-off when the canister empties prevents air from re-entering the system.
ATE brake fluid
The ATE brake fluid we use is selected according to the specification set by the manufacturer of the particular vehicle (DOT 4, or low-viscosity DOT 4 class 6 for vehicles with ESP/ABS).
How it works
How is the brake fluid exchange performed?
The machine brake fluid exchange with the ATE FB 5EV unit keeps your brake system in perfect condition at all times.
Diagnostics — the brake pedal condition is checked, along with a visual inspection of the system for leaks.
The water content of the original brake fluid is measured with a tester.
The level and condition of the fluid in the reservoir are checked.
The ATE FB 5EV unit is connected to the reservoir using a suitable adapter.
The working pressure is set according to the type of brake system in the vehicle.
The old, contaminated fluid is drawn out of the reservoir.
The system is filled with new ATE fluid matching the manufacturer specification.
The circuits are bled and flushed wheel by wheel in the prescribed order.
The colour and cleanliness of the fluid coming out at each wheel are checked continuously.
The reservoir is topped up to the correct level.
The unit is disconnected and a final visual check of all joints for leaks is made.
Test drive and a check of the function and feel of the brake pedal.
