How to Check if Brake Pads Need Replacement

[LaLuna]

Here is a detailed introduction to methods for checking whether brake pads need replacement: 1. Check thickness: New brake pads are generally about 1.5 cm thick. When worn down to one-third of their original thickness (less than 5 mm), immediate replacement is recommended. 2. Listen for sounds: If metallic scraping noises occur during braking, this may indicate the brake pads have worn down to their minimum thickness, causing the wear indicators on both sides to contact the brake disc and produce abnormal sounds, requiring prompt replacement. 3. Check warning indicators: Some vehicle models feature brake wear sensors. Excessive pad wear will cause the sensor wire to contact the brake disc, altering resistance and generating current. This detected signal triggers a brake pad warning light on the dashboard. 4. Feel the pedal: If the brake pedal feels too light or braking requires excessive effort with reduced stopping power, this indicates severe brake pad wear with insufficient thickness, also necessitating immediate replacement.
