What is a brake booster?

A servo is a vacuum amplifier that increases the pressure on the brake master cylinder. This allows the driver to brake effectively with less effort.

What is a brake force regulator?

The equalizer is a pressure regulator in the rear circuit that adjusts the braking force to the vehicle load and prevents the rear axle from locking.

How does brake booster work?

The system uses the pressure difference (vacuum approx. 0.6–0.9 bar) to increase the pressure transmitted to the brake master cylinder.

Does the servo work with the ABS system?

Yes. The servo assists in generating pressure, and the ABS/EBD system electronically controls its distribution between the wheels.

What are the symptoms of a faulty servo?

The most common symptom is a hard brake pedal and increased force required to stop the vehicle.

Why is a brake booster important?

It is responsible for the vehicle's stability during braking, especially during sudden stops and with changing vehicle loads.

How to choose the right servo for your car?

Please take into account the model, year, engine version and compatibility with the brake master cylinder and ABS system.
