Daily Maintenance And Replacement Suggestions For Brake Pads
Brake pad wear judgment
Thickness inspection
Brake pads worn to less than 3 mm must be replaced.
You can observe through the gap between the wheel hubs, or remove the tires to measure (it is recommended to check every 5,000 kilometers).
Abnormal signal
Metal warning sound: When the wear limit is reached, the brake pad warning iron sheet rubs against the brake disc and makes a sharp sound.
The brake foot feels soft or the braking distance is extended.
The brake warning light on the dashboard lights up (some models have sensors).
Visual inspection
Uneven wear, cracks or dents on the surface of the brake pads need to be dealt with in time.
Replacement cycle reference
Ordinary metal brake pads: 30,000-50,000 kilometers (faster wear in congested urban roads).
Ceramic/composite materials: 50,000-80,000 kilometers (high temperature resistance but higher cost).
Influence of driving habits: Frequent emergency braking, driving in mountainous areas, and heavy-loaded vehicles require a shorter cycle.
Replacement precautions
The brake pads on both sides of the same axis need to be replaced at the same time to avoid uneven braking force.
When replacing the brake pads, check whether the brake disc is scratched or deformed (normal thickness should be > 22 mm).
Clean the brake caliper guide and apply special grease to prevent sticking.
Daily maintenance suggestions
Avoid long-term heavy braking: It is recommended to use engine braking on downhill sections.
Clean the brake system: Remove brake dust regularly to prevent corrosion.
Run-in after replacement: New brake pads require 200-300 kilometers of gentle braking to achieve optimal performance.
Professional tips
If there is still abnormal noise or vibration after replacement, it may be that the brake disc is not smooth or improperly installed, and needs to be returned for repair.
Electronic handbrake vehicles require special equipment to retract the motor, and it is recommended to be operated by professional technicians.
Timely maintenance of the brake system can avoid more expensive brake disc damage and ensure reliability during emergency braking. If you are unsure of the operation, be sure to go to a regular repair point for processing.
