Is it necessary to replace the pump when the ABS return pump fails?

[McEleanor]

It is recommended to replace the pump when the ABS return pump fails. Here is a detailed introduction about the automotive ABS system: 1. Overview: The Anti-lock Braking System (ABS) is designed to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding (with a slip ratio of around 20%), ensuring maximum adhesion between the wheels and the road surface. 2. Classification: In ABS systems, the brake pipelines capable of independently adjusting braking pressure are referred to as control channels. ABS systems are categorized into four-channel, three-channel, two-channel, and single-channel configurations based on their control channels.
