Frequently Asked Questions About Bushing AZ400744006012

What vehicles does the Bushing AZ400744006012 fit?

This bushing is specifically designed for Sinotruk Sitrak heavy-duty trucks. It serves as a direct OEM replacement in the brake system assembly, fitting the same mounting points and dimensions as the original factory-installed component.

What is the function of this bushing in the brake system?

The Bushing AZ400744006012 sits between moving metal components within the brake linkage. Its primary role is to reduce metal-on-metal friction, absorb operational vibrations, and prevent accelerated wear on more expensive surrounding parts. Essentially, it acts as a sacrificial wear surface that protects the integrity of the entire braking assembly.

How do I know when this bushing needs replacement?

Common signs include unusual noises during braking (clunking or squeaking at pivot points), increased play or looseness in brake linkage components, uneven brake pad wear, and visible scoring or deformation when the bushing is inspected during routine maintenance. If you notice any of these symptoms, timely replacement prevents cascading damage to adjacent parts.

Is this bushing identical to the original Sinotruk factory part?

Yes. The AZ400744006012 is manufactured to OEM specifications — same materials, same dimensions, same tolerances. It drops directly into the original mounting position without any modification required.

What material is the inner lining made from, and why does it matter?

The inner lining uses a low-friction composite material specifically chosen for its self-lubricating properties and heat resistance. This matters because it significantly reduces the maintenance frequency — the bushing performs reliably over extended service intervals without requiring external lubrication in most applications.

Can I order this bushing in bulk with custom packaging?

Absolutely. Mettlead supports white-label and custom-branded packaging for distributors and aftermarket retailers. Simply contact our sales team with your volume requirements and branding specifications, and we’ll provide a tailored quotation.

How should I store this bushing before installation?

Store the bushing in its original packaging in a dry, cool environment away from direct sunlight and corrosive chemicals. Although the anti-corrosion coating provides protection, proper storage ensures the component remains in perfect condition until it’s ready for installation.
