Understanding Brake Pads: Answering 6 Key Questions

With nearly 90% of households in large cities owning one or two cars, road safety is paramount. The quality of a car’s brake pads directly impacts the driver’s safety. As seasoned drivers, let’s delve into these essential brake pad questions:

How Often Should Brake Pads Be Replaced?

Brake pad lifespan varies based on driving habits. Good driving practices extend pad life.

Frequent highway driving results in longer brake pad life due to less frequent braking compared to city driving.

Regularly check brake pad wear. Replace them when they reach the wear limit.

What Is the Wear Limit for Brake Pads?

New brake pads typically measure around 1-1.5 centimeters in thickness.

With use, thickness gradually decreases. The wear limit is approximately 3 millimeters.

When brake pads are only about 1/3 of their original thickness (around 0.5 centimeters), immediate replacement is necessary.

Do New Brake Pads Need Break-In?

Yes, new brake pads require break-in.

Drive at 50 km/h on a straight road, gently apply the brakes for 3-5 seconds to stop the vehicle. Accelerate back to 40-50 km/h and repeat.

After about 10 repetitions, when you feel the ABS system engage, the break-in process is complete.

Why Do Brake Pads Make Noise?

Brake noise has various causes.

Foreign objects between the brake pad and rotor can create friction and noise, usually not requiring repair.

Wet brake rotors may also cause noticeable noise; simply wipe them dry.

Why Does Brake Performance Deteriorate?

If braking feels weaker, and you need to press the pedal deeper, it indicates worn brake pads.

At this point, braking requires more effort than before. Check if replacement is necessary.

What Should You Do When the Brake Pad Warning Light Activates?

Some vehicles have brake pad warning sensors, but not all wheels are equipped with them.

Don’t rely solely on the warning light. Regularly inspect brake pads to ensure safety.

Remember, brake pads are critical for safe driving.
