To determine whether the brake pad has been worn, you can use the following methods:
1. Visual examination method
Observe brake pad thickness:
Normal brake pads should have a certain thickness.
With use, the thickness of the brake pads will gradually decrease. When the thickness of the brake pads is less than the small thickness recommended by the manufacturer (such as 5 mm), replacement should be considered.
Each brake pad usually has a protrusive mark on both sides, the thickness of this mark is about two or three millimeters, if the thickness of the brake pad is parallel to this mark, it is replaced.
It can be checked using a ruler or a brake pad thickness measuring tool.
Check brake pad friction material:
The friction material of brake pads will gradually reduce with use, and there may be wear marks.
Look carefully at the friction surface of the brake pads, and if you find obvious wear, cracks or falling off, it may be a sign that the brake pads need to be replaced.
2. Auditory examination
Listen to the braking sound:
When the brake pads are worn to a certain extent, there may be a harsh scream or metal friction sound when braking.
This sound indicates that the friction material of the brake pads has worn out and needs to be replaced.
Third, sensory examination
Feel the brake pedal:
When the brake pads are worn to a certain extent, the feel of the brake pedal may change.
It may become hard, vibrate, or respond slowly, which indicates that the brake system needs to be checked and repaired.
Fourth, warning light inspection method
Check the dashboard indicator:
Some vehicles are equipped with brake pad wear warning systems.
When the brake pads are worn to the point where they need to be replaced, a specific indicator light on the dashboard (usually a circle with six solid lines on the left and right sides) lights up to alert the driver that the brake pads have reached the critical point of replacement.
5. Inspection method
Regular inspection and maintenance:
Regular inspection and maintenance of the brake system is an important measure to ensure driving safety.
Automotive maintenance technicians can check the wear of brake pads through equipment and tools, and give accurate replacement recommendations.
In summary, determine whether the brake pad has been worn through visual inspection, auditory inspection, sensory inspection, warning light inspection and inspection and other methods. In order to ensure driving safety, it is recommended that the owner regularly check the brake system and replace the worn brake pads in time.
