How to Check if Brake Pads Need Replacement?

[OCaroline]

Brake pad replacement criteria are as follows: 1. Some vehicles have a brake pad wear limit warning light on the dashboard. Generally, when this light comes on, it indicates that the brake pads need replacement. 2. Brake pads typically have a thickness between 1-1.5cm. When the wear thickness is less than 3mm, the brake pads should be replaced. 3. If the brake pedal needs to be pressed deeper than usual (increased braking travel) or the braking feels softer, it may indicate that the brake pads are nearly worn out. 4. If you hear a squeaking or grinding noise during braking, it is likely the sound of metal-on-metal contact between the brake pad and brake disc, signaling the need for replacement. 5. If there is brake caliper leakage contaminating the brake pads, and oil stains remain even after sanding, the brake pads must be replaced regardless of their remaining thickness.
