Brake pads should generally be replaced after the vehicle has traveled 80,000 kilometers or approximately 4 years, although the replacement time may vary depending on the vehicle's usage. Situations that require brake pad replacement include: 1. When the thickness of the brake pads is reduced to below 0.5 centimeters; 2. When the vehicle produces squealing or hissing noises during braking; 3. If you notice reduced braking efficiency, the brake pedal feels heavy, or the braking distance becomes excessively long, it's time to replace the brake pads. Brake pads are a crucial component of the automotive braking system, typically composed of a steel plate, friction material, and an insulation layer. They function by creating friction against the brake disc when the brakes are applied, thereby achieving the braking effect. As a key safety component, the quality of all braking performance is decisively influenced by the condition of the brake pads.

As a car owner, I usually pay close attention to the feel of the brakes while driving. When the brakes start making a sharp hissing sound, like metal rubbing against metal, it's a signal that the brake pads are nearly worn out. Last time, I noticed it after the brakes became softer—stepping on them didn't slow the car down as quickly as before, and it took a much longer distance to stop. In such cases, it's crucial to address the issue immediately, otherwise, completely worn-out brake pads can damage the brake discs, doubling the repair costs. Generally, it's advisable to check the brake pad thickness every 10,000 to 15,000 kilometers and replace them if they're too thin. Developing a habit of checking the brake fluid level is also beneficial, as maintaining the overall system ensures driving safety. Don't wait until the brakes fail completely to panic—that could lead to rear-end collisions, endangering yourself and others.

I always prioritize safety. Severely worn brake pads can have serious consequences: they may fail to stop the vehicle effectively during rainy weather or on downhill slopes, increasing the risk of collisions. I've experienced a similar situation where the braking distance noticeably increased, nearly causing a collision with the vehicle ahead. This is a red flag, and timely replacement is crucial. Beyond listening for unusual noises, regularly measuring the thickness of the brake pads is essential—replace them if they're thinner than 3mm. Vehicles carrying heavy loads or frequently driven in congested areas experience faster wear, necessitating more frequent inspections. Neglecting replacement can also affect the ABS system, leading to more extensive repairs. Safety is no joke; if you notice any issues, take your vehicle to a professional shop immediately.

When I first started driving, I was completely clueless about brake pad replacement. Later, I learned a bit on my own: when the brake pads look too thin, it's time to replace them; if you hear squeaking noises, it means they're almost worn out. Feeling sluggish brake response while driving is also a sign. Just check them every 10,000 kilometers or so—simply measure the thickness with a caliper. Don’t skimp or delay, or you’ll end up paying more for brake rotor damage repairs. Get them checked at a reputable auto repair shop—they have professional equipment and won’t rip you off. Remember, the braking system is crucial—keeping it updated ensures a smooth journey.

Considering the cost, I try to replace the brake pads as soon as they show signs of wear. Once they're completely worn out, they may damage the brake discs, and replacing them could cost thousands; whereas timely replacement of brake pads only costs a few hundred, saving a lot in the long run. Observing thinning thickness or increased noise during braking are common indicators. Regular checks can prevent unexpected expenses, such as visiting an auto repair shop every 10,000 kilometers. Avoiding hard braking and frequent sudden stops can also extend their lifespan, and good habits help protect the vehicle's overall economy.
