Brake Pads: what it does & when to replace it
Brake pads are the friction material that presses against the rotor to slow the wheel. They are a wear item — most last 40,000–70,000 km depending on driving style and pad compound. Replacement signs include a high-pitched squeal from the wear indicator, a grinding noise (metal-on-metal, meaning the pad is gone), longer stopping distances, or a brake-warning light. Front pads wear faster than rear because the front brakes do most of the work. A competent DIY mechanic can replace pads in about an hour per axle; have a shop do it if you are unsure, since brakes are safety-critical.
DIY difficulty: Moderate DIY (1–2 hours per axle, basic hand tools). Always confirm the correct part for your exact build by VIN before buying.
