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.
