What problems can a faulty vacuum booster pump cause?

[McAlina]

Vacuum booster pump failure can lead to brake dragging, and in severe cases, brake failure. It may also cause heavy steering and abnormal steering noises, with the sound becoming louder at low speeds when turning at larger angles. The primary function of the vacuum booster pump is to assist the driver in increasing braking force and reducing the effort required for braking. Once the booster pump is damaged and loses its assist function, the driver will noticeably feel that much more force is needed for braking, and the original braking force cannot be achieved, resulting in extended braking distances. Fault diagnosis and troubleshooting methods for a faulty vacuum booster pump: 1. Lubricating oil: Check the viscosity of the lubricating oil. If it does not meet the standards, replace it with oil of the appropriate viscosity to ensure proper oil viscosity. 2. Pipes: Inspect all pipes for air leaks. If leaks are found, replace the leaking components. 3. Parts: Check for wear on parts. If wear is detected, repair the worn areas or replace the parts with new ones.
