Why Does the Brake Pump Fail?
2 Answers
Brake pump failure can occur due to the following reasons:1. Quality issues with the brake pump: The brake caliper is not a wear-prone component, and its failure is mostly due to quality defects. Dirty brake fluid can clog the brake lines, increasing pressure on the master cylinder. Over time, this leads to ineffective braking and potential damage to the pump.2. Caliper damage from delayed replacement of brake discs and pads: Continued use of worn-out brake discs and pads beyond their limits can cause caliper damage.3. Poor quality or aged brake fluid: Inferior or deteriorated brake fluid can corrode the master cylinder's sealing diaphragm, leading to poor sealing over time. This results in the inability to maintain oil pressure, ultimately causing pump failure.
That time my car was driving on the road, when I stepped on the brake, it felt unusually hard, and I almost rear-ended someone, which gave me a scare. Later, I took it to the repair shop for inspection, and the technician said the brake pump was broken, mainly because I hadn't changed the brake fluid for years. The deteriorated fluid caused internal parts to rust and corrode, and the piston got stuck. This thing needs careful maintenance. If you hear unusual noises or the pedal travel becomes longer while driving, it might be a sign the pump is about to fail. An experienced driver friend reminded me to check the fluid level and quality during every maintenance check. If it fails on the highway, the consequences could be unthinkable. Remember to change the fluid regularly, generally every two years or 30,000 kilometers, which can greatly reduce the risk.
