Do brake pads need to be replaced all four at once?

[EmersonAnn]

Brake pads do not necessarily need to be replaced all four at once. You can replace all four simultaneously, or just the front two or rear two. However, brake pads should not be replaced individually; it's best to replace them in pairs. Otherwise, differences in braking force may cause issues like pulling to one side. Typically, new brake pads are about 1.5 cm thick, and there is a raised indicator at both ends of the pad, approximately 3 mm high. If the brake pad thickness wears down to this indicator level, immediate replacement is required. Brake pads, also known as brake linings, are critical safety components in a vehicle's braking system, playing a decisive role in overall braking performance.
