How to define a high-quality heavy-duty brake caliper?

In our production base, the production of every batch of trailer or heavy truck calipers must pass a double checkpoint:
1.Spectrometer testing (material qualification): Before pouring and when blanks enter the warehouse, we use a spectrometer to analyze the grade of ductile iron. Only materials that meet the QT450-10 standard or higher can enter the machining process.
2.Brake pad matching test (performance benchmarking): A caliper is not just a metal shell; its clearance with the brake pad and piston thrust directly determine the braking effect.
We know deeply that as factory replacement parts for mainstream brands, the authenticity of materials is the foundation of survival. If you are looking for a heavy-duty caliper supplier with strict quality traceability, welcome to contact us to discuss.
