Why does the hydraulic brake fail to stop the vehicle?
3 Answers
Reasons for hydraulic brake failure: Lack of brake fluid in the braking system. Solution for hydraulic brake failure: Simply add brake fluid. More information about the braking system is as follows: 1. The braking system consists of a control system, hydraulic system, and power assist system. 2. The principle of the braking system is to create tremendous friction, converting the vehicle's kinetic energy into thermal energy. 3. The braking system is one of the most critical components of a car. During acceleration, the vehicle converts chemical energy into thermal and kinetic energy, while during braking, the braking system converts the car's kinetic energy into thermal energy dissipated into the air.
I've encountered this situation several times. When driving an old truck, the brakes just wouldn't hold after stepping on them, and I almost hit the guardrail. Later, the inspection revealed that the main issue was low brake fluid, possibly due to a leaking reservoir or not changing the fluid on time. Additionally, the brake pads were severely worn, leaving only a thin layer, which reduced friction effectiveness. If the brake pedal feels spongy or sinks too deep, it indicates there might be air in the system that needs bleeding. I remember trying to save money by not fixing it when I was younger, but now I understand that the braking system is a matter of life and death and must be checked regularly. I suggest checking the fluid level under the hood yourself every six months and listening for any unusual noises from the brakes. Be especially careful before long trips—don't be as careless as I was.
I've seen many cases of brake failure. Typically, there are several key reasons why brakes fail to stop effectively: insufficient or degraded brake fluid leading to inadequate hydraulic pressure; wear and leakage in the master cylinder or wheel cylinders; cracks in the brake lines allowing air to enter; or excessive wear on brake pads and rotors. Symptoms while driving include a longer pedal travel and a spongy feel. It's crucial to address these issues promptly to avoid loss of control during downhill driving or emergency braking. It's recommended to visit a reputable repair shop for a comprehensive inspection of the hydraulic system's integrity and the brake fluid's moisture content. Prevention is better than cure—regularly replacing brake fluid and pads is essential.
