What are the symptoms of a faulty car brake pump?
2 Answers
When a car brake pump fails, it can cause symptoms such as brake pulling, brakes not releasing, and brake failure. Below are the specific symptoms of a faulty car brake pump: Brake Pulling: When braking, the car pulls to one side, especially in vehicles without ABS (Anti-lock Braking System), making it difficult to control the direction. Brakes Not Releasing: When pressing the brake pedal, it feels unusually high and stiff or lacks free travel, making it hard to start the car or causing difficulty while driving. Brake Failure: While driving, pressing the brake pedal once or multiple times results in the pedal going all the way down with no braking effect, indicating sudden brake failure. In such cases, replacing the piston seals of the master and slave cylinders or directly replacing the brake pump may be necessary.
I remember that time driving home when suddenly the brake pedal felt spongy, offering no resistance when pressed. The car slowed down as if sliding on ice, almost hitting the vehicle in front. Upon inspection, it turned out the brake master cylinder was faulty—it's responsible for pushing brake fluid to generate pressure, and its failure caused hydraulic loss, significantly increasing braking distance. Early signs might include brake fluid leakage, such as small oil stains under the parking spot accompanied by a distinct smell. It's advised to immediately drive slowly to a safe area with hazard lights on, avoiding sudden brakes to prevent loss of control. Regularly monitor pedal feel and check brake fluid color and level during daily driving. If any abnormality is detected, head to a repair shop immediately—safety comes first.
