When should brake pads typically be replaced?

Brake pads should typically be replaced when they are worn down. This wear can vary significantly based on various factors such as driving habits, the type of vehicle, and the materials of the brake pads themselves. Regular inspection is essential, as brake pads have wear indicators that can signal the need for replacement. Waiting for the pads to wear out completely can lead to reduced braking performance and potential damage to other brake components, such as the rotors. Thus, monitoring the thickness of the brake pads and replacing them before they reach critical wear levels ensures safe and effective braking.

Other options suggest arbitrary timelines or conditions that may not reflect the actual state of the brake pads; for example, replacing brake pads every six months does not take into account individual usage and can lead to unnecessary replacements. Additionally, relying solely on noise can be problematic, as some brake pads may only make noise when they are significantly worn, which could compromise safety. Lastly, timing replacement based on brake fluid changes doesn't directly correlate to pad wear and could disregard the actual condition of the pads.
