As the core component of the vehicle braking system, the correct installation and maintenance of truck brake pads directly affect driving safety. Whether it is new car assembly or daily maintenance, it is crucial to master scientific operation methods. This article will systematically introduce the operation points of truck brake pads from four aspects: installation, inspection, replacement and maintenance.
1. Preparation before installation
Before installing the brake pads, make sure that the brake system is in a clean state. First, remove the old brake pads and thoroughly clean the surface of the brake caliper and brake disc to avoid residue affecting the performance of the new pads. At the same time, check whether the brake disc has excessive wear or cracks, and replace it in time if any problems are found. In addition, lubricating the contact points of the sliding pin and return spring of the brake caliper can reduce friction noise and extend the life of the components.
2. Correct installation of brake pads
During installation, the brake pads and caliper slots must be strictly aligned to ensure that the fixing bolts or retaining springs are firmly locked. Some high-end models use a floating brake pad design, and attention must be paid to the direction to avoid reverse installation and brake failure. After installation, manually return the caliper piston to leave enough clearance for the brake pads. Finally, tighten the fixing bolts slowly in multiple times to prevent deformation caused by uneven force.
3. Regular inspection and replacement standards
It is recommended to check the thickness of the brake pads every 20,000 to 30,000 kilometers. When the wear is reduced to 1/3 of the original thickness (usually 3-5 mm remaining), it needs to be replaced immediately. Abnormal wear such as eccentric wear, cracks or metal friction sound is a direct signal for replacement. It is recommended to operate in pairs when replacing, that is, replace two brake pads on the same axis at the same time to maintain the balance of braking force.
4. Daily maintenance precautions
Avoid long-term frequent braking to cause overheating of the brake pads. When driving in mountainous areas, low gear can be used with engine braking. Clean the oil or foreign matter on the surface of the brake pads regularly. If brake fluid leakage is found, stop and repair immediately. In addition, the new brake pads need to go through a running-in period of about 200 kilometers to achieve the best braking effect. Avoid sudden braking during this period.
Scientific operation and maintenance can not only extend the service life of the brake pads, but also significantly improve driving safety. It is recommended that drivers combine the vehicle manual to develop a personalized maintenance plan to ensure that the braking system is always in the best condition.
