Brakes can be one of two types -- either disc or drum. Both have master cylinders and one or more pistons, and their network of lines and hoses fills with brake fluid when the brake pedal is pressed. How both systems work is simple: pistons move along the cylinder's bore, pressurizing the fluid as they travel, and it goes down the lines and hoses.
However, where drum brakes use a combination of brake drums and brake shoes, disc brakes use brake calipers with brake pads installed on them, as well as brake rotors. In drum brake systems, the fluid makes the drum and shoe clamp together. In disc brake systems, the rotors clamp to the calipers and pads. Both processes create friction, and the resistance helps a vehicle slow and stop.
Unfortunately, with use for long enough, and plain old age, ending up with a worn-out brake is likely sooner or later. Which of its parts needs replacing depends on the outcome of a brake inspection. The question of how long brakes last, then? It really depends on the condition of brake parts rather than particular mileage. Luckily, there's a way you can tell if your front or rear brakes are going bad, though: look for symptoms. They include:
- Shuddering, strange sounds, and drifting sideways during braking
- An unusually soft- or low-feeling brake pedal
- Reduced brake grip, coupled with taking longer to slow and stop than usual
- Warning lights on the dashboard
Grinding noises are a worst-case scenario. They usually indicate direct rotor contact with calipers because of worn-out pads.
