Frequently Asked Questions – Brake Chamber WG9000360613

What does the “R” designation mean in this brake chamber’s name?

The “R” stands for Right Side. This brake chamber is specifically designed for installation on the right-side brake assembly of compatible Sinotruk heavy-duty trucks. For balanced braking, it should be paired with the corresponding left-side chamber on the same axle.

What does the L=242 specification refer to?

The L=242 indicates the stroke length of the brake chamber diaphragm, measured at 242 millimeters. This stroke length determines how far the push rod extends when air pressure is applied, which directly affects braking force output. It’s a critical dimension — using the wrong stroke length can compromise braking performance.

Is this brake chamber an original OEM part or an aftermarket replacement?

This brake chamber is manufactured to OEM-equivalent standards using the original Sinotruk part number WG9000360613. It matches the factory specifications for dimensions, materials, and performance, ensuring a direct drop-in replacement without any modifications needed.

How can I verify that this brake chamber fits my specific truck model?

The most reliable method is to cross-reference the OEM part number WG9000360613 with your vehicle’s parts catalog. If you’re unsure, simply provide us with your truck model, VIN, or chassis number, and our technical team will confirm compatibility before you place your order.

What causes a brake chamber to fail, and when should it be replaced?

Common failure modes include diaphragm rupture (causing air leaks), corrosion of the steel housing, and push rod seal degradation. You should replace the brake chamber immediately if you notice air hissing from the unit, uneven braking, or if the push rod fails to retract fully. Preventive replacement during scheduled maintenance intervals is also recommended for fleet safety.

Can I order this brake chamber with my own brand packaging?

Absolutely. Mettlead offers white-label and custom packaging services. You can supply your own artwork and branding guidelines, and we’ll package each unit accordingly — making it shelf-ready for your market without additional handling on your end.
