Abnormalities in the Vehicle Braking System?

[LeLuna]

Car braking system's condition determines the safety of passengers inside the vehicle. Only when it is in a healthy state can it successfully decelerate or even stop the vehicle according to the driver's intention. Therefore, any abnormalities should be repaired immediately. Here are some common abnormalities in the vehicle braking system: 1. If the warning light on the dashboard lights up, it indicates a problem in a certain part of the braking system. You should go to a 4S shop for inspection and repair immediately. Ignoring it and continuing to use the vehicle may lead to unimaginable consequences. 2. After releasing the brake when starting the car, if you notice friction sounds between the brake pads and the brake disc, this is not an abnormal phenomenon. 3. The handbrake cable will lengthen after being used for a period of time, which is also normal. The handbrake cable is composed of multiple metal wires and has a certain degree of elasticity under force. After some time, it will be slightly longer than when the car was new, but this will not affect the parking brake function. 4. Rust on the brake disc may affect its use. The brake disc is mainly made of iron. If the vehicle is not used for a long time, the brake disc will react with oxygen and moisture in the air, causing oxidation, i.e., rust. However, during driving, the rust will be removed through the operation of the braking system, and it will not affect normal use. 5. The brake disc heats up after use. This is because braking is achieved through friction between the brake disc and the brake pads, during which kinetic energy is converted into mechanical energy and heat energy, thus generating some heat.

Last time I drove my car, I encountered brake issues. The pedal felt unusually soft and spongy, which was very concerning. I immediately pulled over to check and found the brake fluid reservoir level had dropped below the warning line – most likely due to a leak somewhere in the system. Looking back, the brakes had been squeaking badly recently, probably because the pads were worn down close to the wear indicators. The most annoying part was the steering wheel shaking violently while driving – a clear sign of warped brake rotors. A reminder to everyone: if you notice longer braking distances or abnormal pedal feel, don’t delay – get it inspected immediately. Also, always pay attention to whether the ABS warning light is illuminated, because if this system fails, the wheels can lock up during emergency braking.

Speaking of brake system issues, I've had my fair share of experiences. Last winter while driving, the brake pedal felt as hard as a rock when pressed. Later inspection revealed a vacuum booster pump leak. The mechanic even showed me the brake pads - the thinnest part was down to just 2mm, with the friction material almost completely worn away. You need to be extra careful during rainy seasons, as water rusting on brake rotors can reduce braking power, especially feeling less responsive for the first few brakes after going through puddles. If you hear metal scraping sounds, that's definitely the brake pad wear indicator telling you it's time for replacement. Regularly changing brake fluid is particularly crucial - its boiling point decreases when it absorbs water, making brake failure more likely during continuous braking.

Brake abnormalities are no joking matter. The most common issue is reduced braking power due to worn brake pads, at which point the brake discs may already have deep grooves. If the steering wheel shakes violently during braking, it's likely caused by warped brake discs. Additionally, leaking brake lines can result in a longer pedal travel, making the pedal feel soft and lacking in pressure. When the pedal becomes extremely hard to press, it may indicate a faulty vacuum booster. These malfunctions can range from simply increasing stopping distance to complete brake failure. If any abnormalities are detected, it's best to seek repairs immediately - never compromise on safety.
