What is the standard thickness of brake pads?
1 Answers
The standard thickness of brake pads is generally around 1.5cm, and it will gradually decrease due to friction during braking operations. The critical thickness for brake pads is typically around 2 to 3 millimeters. If the brake pad thickness is less than 3 millimeters, it must be replaced. The thickness of brake pads can often be visually inspected, as some brake pads are visible through the gaps in the wheel hub. If the brake pads have worn down to one-third of their standard thickness, replacement is recommended. However, due to the wheel hub design in some car models, it can be difficult to check the brake pad thickness without removing the tires, which can be quite troublesome. Some car models are equipped with an indicator light on the dashboard (usually near the handbrake light) that alerts the driver when the brake pads are too thin. There are also specialized tools available for measuring brake pad thickness, which can provide a more accurate assessment. Additionally, drivers can rely on their senses to judge; if the brake feels hard, it may indicate that the brake pads are too thin and lack sufficient friction, requiring immediate replacement to avoid accidents. The replacement cycle for brake pads depends on the vehicle's operating environment and driving habits. Generally, replacement should be considered after driving approximately 40,000 kilometers. If visual inspection reveals that the brake pads have thinned or braking becomes difficult, timely replacement is advised, preferably at a professional repair shop for inspection and replacement.
