What needs to be replaced when the brakes are not working well?

When the brakes are not working well, the brake pads or brake discs need to be replaced. Here is some relevant information about brakes: 1. Brakes: The braking system generates friction between the brake pads and the drum or disc, converting the kinetic energy of the moving vehicle into heat during this process. Common types of braking systems include "drum brakes" and "disc brakes." 2. Applying brakes: When braking, release the brake before the vehicle comes to a complete stop. Continuously pressing the brake can cause a significant impact force when the vehicle stops. Therefore, release the brake once before the vehicle fully stops, then gently apply the brake again until the vehicle comes to a halt.

As a mechanic with over a decade of experience, I must emphasize that brake issues are nothing to take lightly. Common causes include excessively worn brake pads, uneven brake disc surfaces, or deteriorated brake fluid leading to a spongy pedal. When replacements are needed, start with the brake pads—they're wear-prone components that thin out with frequent use. Next, inspect the brake discs; replace them if deeply scored or below minimum thickness. Don't overlook brake fluid—aged fluid compromises the hydraulic system, causing delayed braking. A bi-annual replacement is safest. Issues like leaking lines or ABS pump failures are more complex—never attempt DIY fixes; leave them to professionals. Remember: safety outweighs cost. Sudden brake failure while driving is extremely hazardous. Regular maintenance prevents major headaches.

As an experienced car enthusiast who often tinkers with my own vehicle, I always prioritize checking easily replaceable parts when the brakes aren't performing well. Last time my car had braking issues, the problem turned out to be severely worn brake pads - replacing them made an immediate difference. If you notice longer pedal travel or unusual noises, the brake discs might be cracked and need replacement, though this is more costly. Contaminated brake fluid is also common - over time it gets dirty and affects pressure, so regularly test its water content; if it exceeds 3%, it's time for a change. More serious issues like leaking connections in the brake lines require complete replacement of the affected section. I recommend checking brake pad depth monthly yourself. If anything feels off, don't wait - take it to a professional repair shop immediately. They can use force gauges to precisely identify faulty components. Safety comes first - don't risk it to save a few bucks.

As a seasoned driver who has been driving all my life, I understand the risks of brake failure. Most of the time, it's due to worn-out brake pads or warped rotors, and replacing them with genuine parts will do the trick. If the brake fluid is dirty, it needs to be changed too, otherwise the pedal will feel spongy and unresponsive. Simple issues like pads and fluid can be handled by yourself and don't cost much; for more complex problems like a faulty pump or ABS sensor, leave it to the mechanics. Address the issues promptly—don't delay, as it's a matter of life and death and not something to take lightly.
