Brake boosters and force regulators for optimal pressure distribution
Optimal servos and braking force correctors
Brake servo and brake boosters are key components of the braking system, supporting its efficiency and improving driving safety. A brake booster increases braking power, reducing driver effort, while a brake booster optimizes the distribution of force across the vehicle's axles, preventing wheel lockup. At Global Parts, you'll find a wide selection of used car parts , including brake boosters and brake boosters, ideal for BMW , Audi , Mercedes , Volkswagen , Mini , and more .
What are servos and brake force correctors – definition and principle of operation
A brake booster (vacuum booster) is a component of a brake assist system that uses pressure differential (usually vacuum generated by the engine or a vacuum pump) to increase the force applied to the brake master cylinder. In practice, this means the driver can generate up to 3–5 times more braking power with the same pedal pressure. Standard servos range in diameter from 7 to 11 inches, which directly affects the power assist. The brake force regulator (rear axle pressure regulator) dynamically adjusts rear brake pressure based on vehicle load. In vehicles without electronic EBD, it operates mechanically or hydraulically, limiting pressure on the rear wheels during heavy braking. This maintains directional stability and traction. In modern designs (e.g. in the BMW 3 Series, Audi A4 or Volkswagen Passat models), the function of the classic equalizer is often supported by the ABS/EBD system, but the controller itself is still responsible for the basic calibration of the braking force distribution.
What are the functions of servos and braking force correctors ?
Servos and brake force regulators play important roles in the braking system:
- Increased braking power – The servo increases the pressure on the brake pedal, which facilitates effective braking.
- Optimised brake force distribution – Brake force regulator prevents the rear wheels from locking, especially in low grip conditions.
- Improved driving comfort – Thanks to the smooth operation of the braking system, driving becomes more comfortable and safe.
Technical parameters and compatibility with the braking system
In practice, the compatibility of the servo and the brake force corrector depends on several technical parameters:
- servo diameter (e.g. 8", 9", 10"),
- type of attachment to the front bulkhead,
- length of the pin cooperating with the brake master cylinder,
- pump type (1- or 2-circuit),
- type of system (ABS / ABS + EBD / without ABS).
Example operating parameters
| Element | Function | Typical parameters | Impact on safety |
|---|---|---|---|
| Brake servo | Pressure force support | Vacuum 0.6–0.9 bar, diameter 7–11" | Shortening the braking distance by up to several meters at 100 km/h |
| Brake force corrector | Rear axle pressure adjustment | Proportional pressure reduction with load increase | Traction stability and slip limitation |
Correct matching of these components to the vehicle model directly affects braking efficiency, even wear of pads and discs, and optimal operation of the entire hydraulic system.
Why is it worth taking care of servos and braking force correctors ?
Malfunctioning brake boosters and regulators can lead to reduced braking performance and increased road safety. Typical symptoms include:
- Hard brake pedal – May indicate a brake booster failure.
- Uneven braking – Problems with the brake booster can cause excessive braking on one axle.
- Noises when braking – A damaged servo or equalizer can produce unusual noises. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full efficiency to your braking system.
Step-by-step procedure for system operation during braking
- The driver presses the brake pedal.
- The servo uses vacuum to increase the pressure on the brake master cylinder.
- The pump generates hydraulic pressure in the brake lines.
- The brake force regulator regulates the pressure ratio between the front and rear axles.
- The calipers press the pads against the discs, generating friction and reducing the vehicle's speed. In a properly functioning system, the braking force distribution is on average around 60-70% front / 30-40% rear, which ensures stability and optimal use of tire grip.
How to choose the right servos and braking force correctors ?
When choosing servos and brake force correctors, there are several key aspects to consider:
- Vehicle-specific fit – Every braking system has its own specific technical requirements. At Global Parts, you'll find brake boosters and brake boosters perfectly matched to BMW , Audi , Mercedes , Volkswagen , Mini , and more .
- Technical condition – Used parts should be free from leaks, mechanical damage and pneumatic system defects.
- Brake System Compatibility – Make sure the components you choose are compatible with your vehicle's design and specifications.
Fit, OEM, VIN and integration with other components
The selection of a brake servo and brake booster should take into account design compatibility with the brake master cylinder, brake lines, and ABS system. In practice, matching is based on the vehicle's model, year, engine version, and VIN. These elements work directly with:
- brake pump,
- brake fluid reservoir,
- ABS/ESP module,
- calipers and brake cylinders. Proper compatibility ensures not only safety, but also savings in operating costs – proper pressure distribution reduces uneven wear of friction elements and improves the durability of the entire system.
Why is it worth choosing used servos and braking force correctors ?
Used car parts , such as used servos and brake force correctors , is a practical solution that allows you to save money while maintaining high quality. By choosing used braking system components, you gain:
- Lower costs – Used components are much cheaper than new ones, but offer equally high quality.
- Ecology – Recycling parts supports environmental protection and reduces waste.
- A wide range – In our store you will find used servos and braking force regulators for the most popular car brands.
How to take care of servos and braking force correctors ?
To ensure that servos and brake force correctors function reliably for a long time, it is worth following a few rules:
- Regular inspections – Check the condition of braking system components during periodic technical inspections.
- Maintain proper brake fluid level – Low fluid levels can damage the servo and other components.
- Respond to symptoms of malfunction – Noises, uneven braking or problems with the brake pedal are signals that faulty parts need to be replaced. If replacement is necessary, Global Parts has the right used car parts to restore the effectiveness and reliability of your braking system.
FAQ – Frequently asked questions about servos and brake force regulators
| Question | Answer |
|---|---|
| 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. |
