Frequently Asked Questions – Brake Caliper R AZ4007443020

What trucks does the Brake Caliper R AZ4007443020 fit?

This right-side brake caliper is specifically designed for Sinotruk Sitrak heavy-duty trucks equipped with disc brake systems. It matches the OEM part number AZ4007443020, so it’s a direct bolt-on replacement — no aftermarket adapters needed.

Is this caliper for the left or right side?

This particular unit is the right (R) brake caliper. If you need the left-side counterpart, please contact us with your requirements and we’ll confirm availability.

What material is the caliper housing made from?

The housing is constructed from high-strength cast iron, which provides excellent heat dissipation and resistance to cracking under the thermal stress of heavy braking. Additionally, it features an anti-corrosion surface treatment to extend its service life in harsh road conditions.

How do I know when this brake caliper needs replacement?

Common signs include uneven brake pad wear, the vehicle pulling to one side during braking, brake fluid leaks around the caliper, or a seized piston that prevents proper pad retraction. If you notice any of these symptoms on the right-side disc brake, this caliper is likely due for replacement.

Can I order this caliper with my own brand packaging?

Absolutely. Mettlead offers both neutral (white-label) and fully custom packaging options. This is especially useful for distributors and aftermarket brands who want to maintain their own product identity while sourcing factory-direct quality.

What quality checks does this brake caliper go through before shipping?

Each unit undergoes a multi-point inspection process that includes dimensional accuracy verification of piston bores, surface finish assessment, mounting bracket alignment checks, and a final visual inspection for casting defects. Only calipers that pass every stage leave our facility.
