There is no fixed standard for the service life of Truck Brake Discs. It is mainly affected by five factors: load capacity, driving habits, road conditions, brake pad matching and maintenance conditions. The details are as follows:
First is the truck's load capacity. When the truck is overloaded or heavily loaded, the Truck Brake Disc has to bear greater braking pressure and friction, which will accelerate the wear of the disc surface. For example, the service life of brake discs for heavy-duty trucks that are fully loaded for a long time may be 30%-50% shorter than that for lightly loaded trucks.
Second is driving habits. Frequent sudden braking will cause the temperature of the brake disc to rise sharply in a short time. Repeated alternation of cold and heat is likely to cause cracks and deformation on the disc surface, shortening its service life. On the contrary, driving at a constant speed and braking gently can reduce the wear of the brake disc and extend its service life.
Third is road conditions. When driving on mountain roads or ramps for a long time, trucks need to brake frequently to control the speed, so the Truck Brake Disc is used more frequently and wears faster. When driving on flat highways, the number of brakes is less, so the service life of the brake disc is relatively longer.
Fourth is brake pad matching. Using brake pads with excessively high hardness or poor quality will aggravate the wear of the brake disc. It is necessary to select compliant brake pads that match the material of the brake disc to reduce excessive wear on the disc surface.
Fifth is maintenance conditions. If the dust and foreign matter on the surface of the brake disc are not cleaned for a long time, or brake system faults (such as abnormal brake clearance) are ignored, it will lead to abnormal wear of the brake disc. Regular inspection and cleaning can timely prevent the aggravation of wear and extend the service life.
