What Are the Reasons for Ineffective Braking?

The reasons for ineffective braking: 1. Excessive wear of brake pads: Brake pads have a service life. Once they are excessively worn, they should be replaced promptly. Otherwise, it can easily lead to ineffective braking and may also affect the brake discs. In severe cases, it can cause damage to the braking system. 2. Deterioration of brake fluid: Over time, brake fluid absorbs moisture from the air, which lowers its inherent boiling point. When the boiling point drops significantly, it can affect the vehicle's braking performance, resulting in ineffective braking. 3. Driving too fast in rainy conditions: In rainy weather, a layer of water film forms on the tires, which can slightly reduce their braking performance. If you drive at high speeds under these conditions, ineffective braking may occur. 4. Newly replaced brake pads: Newly installed brake pads have not yet been properly broken in with the vehicle.

I have over a decade of driving experience. That time when driving on the highway in the rain, I noticed the braking wasn't very effective when I pressed the brake pedal, almost causing a rear-end collision. After stopping to check, I found the brake fluid level was low due to a small leak in the system, which over time had reduced the fluid and affected braking power. Another common issue is excessive wear on the brake pads; once the metal layer is worn through, friction decreases, requiring new pads. Sometimes, air gets into the brake system, making the pedal feel spongy, necessitating a bleed. Wet roads or shallow tire tread can also cause slipping and reduce braking effectiveness. It's advisable to regularly check the condition of the brake fluid and pad thickness, not waiting until an accident occurs to pay attention. Make it a habit to have a technician inspect the brakes during every maintenance session—safety first to avoid accidents.

Experiencing a situation where the brakes fail to stop the car is quite frightening. I immediately slowed down and pulled over. There could be various reasons, such as warped or uneven brake discs causing vibrations when pressed, affecting stopping distance; or issues with the brake pump leading to insufficient pressure, or dirty and clogged brake fluid lines. An ABS system malfunction might also prevent effective anti-lock braking. Start with the basics: open the hood and check if the brake fluid reservoir is at the proper level—top it up with specialized fluid if low; listen for any unusual noises near the wheels to assess pad wear. Avoid overloading the vehicle or sudden acceleration and braking to reduce stress on the system, ensuring reliable braking in critical moments. Promptly sending the car for repairs is essential—don’t delay.

I encountered a situation where the brakes weren't performing well when I was a new driver. The repair shop owner mentioned several main factors: the brake pads had worn thin and needed replacement; the brake fluid had aged, absorbed moisture, and became diluted, reducing pressure; or the tires were worn out, leading to poor grip and skidding. Another possibility was air entering the brake lines, causing no feedback when pressing the pedal. He suggested performing simple monthly checks: visually inspect the fluid level between the marks; use a flashlight to check the remaining thickness of the brake pads; and lightly press the pedal after starting the car to feel its firmness. If any issues are found, address them promptly and avoid driving at high speeds, especially on slippery rainy roads where extra caution is needed. It's important to enhance safety awareness while driving.
