When should brake pads be replaced based on their original size?

Brake pads are critical components of a vehicle's braking system, and their replacement is essential for maintaining optimal braking performance and safety. When assessing when to replace brake pads, their wear relative to their original size is an important factor.

The recommended practice is to replace brake pads when they have worn down to about a quarter (1/4) of their original thickness. At this point, they may not provide adequate stopping power and could lead to increased stopping distances. Additionally, worn pads can cause damage to the rotor, leading to more extensive repairs and costs.

Choosing to replace the brake pads at this stage ensures that there is enough material to maintain effective braking and avoid potential safety hazards. This guideline helps in timely maintenance, ensuring that the vehicle remains reliable and safe for operation.
