The methods for judging the wear degree of brake pads mainly include the following:
Observe the thickness: The thickness of new brake pads is usually about 1.5 cm. When the brake pads are worn to only 0.5 cm, that is, the thickness is reduced to 1/3 of the original, you need to consider replacing them. Especially when the thickness of the brake pads is less than 5 mm, they should be replaced immediately, because the braking effect will be significantly weakened at this time.
Check the warning light: Some vehicles are equipped with a brake pad wear reminder function. When the brake pad warning light on the dashboard lights up, it means that the brake pad wear has reached the critical value and needs to be replaced immediately.
Listen to the sound: If you hear a harsh metal friction sound when you step on the brakes, this is usually a signal that the brake pads are worn to the limit. At this time, the limit marks on both sides of the brake pads will make an abnormal sound when they touch the brake disc, prompting the owner to replace the brake pads.
Feel the braking effect: If you feel that the brake pedal becomes light when you step on it, or the braking force is insufficient, you may need to replace the brake pads. A good brake system can provide stable braking effect, and regular inspection and maintenance can help maintain the best braking performance.
The impact of different models and driving habits on brake pad wear: Different models and driving habits will affect the wear rate of brake pads. Generally speaking, you need to consider replacing brake pads after driving about 60,000 kilometers. In addition, frequent emergency braking or long-term driving on rough roads will also accelerate the wear of brake pads.
