What Causes the Restricted Brake Booster System in Golf 7?

If the brake booster system in Golf 7 is restricted, check the vacuum pump or whether there is any air leakage in the pipelines. Additionally, inspect the vacuum pressure sensor. The brake booster system refers to the vacuum booster, but some models use an electric booster instead. Therefore, if the brake booster system fails, the brake pedal will feel heavier when pressed. Definition of Brake Booster: It is a brake assist device widely used in light to medium-duty vehicles, which can be roughly categorized into vacuum boost, hydraulic boost, and pneumatic boost. It includes a hydraulic cylinder, support arm, pressure arm, and brake plate. The feature is that the hydraulic rods at both ends of the hydraulic cylinder are connected to the support arm and pressure arm, with a rubber-wheeled brake plate installed on the pressure arm. Working Principle of Brake Booster: This utility model can be installed between the two wheels of the vehicle chassis without affecting normal driving. The hydraulic cylinder opens an angle between the support arm and the pressure arm through the extension of the hydraulic arm, causing the brake plate to contact the ground. This increases the friction between the brake plate and the ground, ensuring the vehicle stops quickly.

Avoid emergency braking; 3. Prevent overloading; 4. Avoid long-distance trips; 5. Do not drive at high speeds; 6. Use high-quality gasoline; 7. Do not remove the speed limiter prematurely; 8. Shift gears promptly; 9. Properly adjust the ignition and fuel supply systems. The break-in period generally refers to the process where mechanical components make initial contact, friction, and engagement during early operation. Successfully completing the break-in period plays a crucial role in determining the vehicle's future durability, frequency of issues, fuel efficiency, and other performance indicators.
