Core Function

1. Converts pneumatic pressure into mechanical force to actuate brake shoes, a critical part of heavy duty truck brake parts.

2. Provides secure parking brake function via internal spring force, preventing vehicle movement when parked on inclines.

3. Resists fatigue and deformation, ensuring reliable operation over millions of braking cycles.

4. Fully OEM-compatible for seamless replacement, restoring the actuation and parking brake function of the brake system.

Application Scenarios – Where This Brake Chamber Fits

The Brake Chamber 812W50410-6883-2424 is designed as a direct replacement for the original unit installed on Sinotruk Sitrak heavy-duty trucks. Here’s when and where you’ll need it:

Compatible Vehicle Models

• Sinotruk Sitrak C7H – Heavy-duty tractor and cargo configurations
• Sinotruk Sitrak C5H – Medium-heavy logistics and distribution trucks
• CNHTC / HOWO series (where OEM cross-reference applies)

Common Replacement Scenarios

• Diaphragm Failure: Over time, the rubber diaphragm cracks or develops leaks, causing slow brake response or air loss in the system.
• Spring Fatigue: After years of service, the parking brake spring weakens, reducing holding force and creating a safety risk on grades.
• Corrosion Damage: Road salt, moisture, and debris can corrode the housing, leading to structural compromise and eventual air leaks.
• Routine Maintenance Overhaul: During scheduled brake system inspections, fleet managers replace aging brake chambers as a preventive measure to avoid on-road failures.

Whether your trucks operate in mining, long-haul logistics, construction, or port operations, this brake chamber is built to handle the demand. For more Sitrak braking system components, explore our full braking parts catalog.

Frequently Asked Questions – Brake Chamber 812W50410-6883-2424

What type of brake chamber is the 812W50410-6883-2424?

This is a Type 24/24 combined spring brake chamber. It integrates both the service brake function (air-applied) and the parking brake function (spring-applied) into a single unit. The “24/24” designation refers to the effective diaphragm area for both the service and parking chambers.

How do I know when this brake chamber needs replacement?

Common signs include audible air leaks near the rear brake assembly, slow parking brake engagement, the truck creeping on inclines with the parking brake applied, or visible cracks and corrosion on the chamber housing. If your air system loses pressure faster than normal, a failing brake chamber diaphragm is often the culprit.

Is this brake chamber an exact OEM replacement for Sinotruk Sitrak trucks?

Yes. The 812W50410-6883-2424 is manufactured to match OEM dimensions, pressure ratings, and mounting specifications. It installs directly in place of the original factory-fitted brake chamber without any modifications required.

Can I use this brake chamber on other Sinotruk models like HOWO?

While this part is specifically designated for Sitrak models, some HOWO variants share compatible rear brake assemblies. We recommend confirming the OEM part number cross-reference with our team before ordering to ensure a proper fit.

What is the expected service life of this brake chamber?

Under normal operating conditions, with proper air system maintenance and regular inspections, this brake chamber typically lasts 200,000–300,000 km or 3–5 years. Harsh environments (mining, extreme temperatures) may reduce service intervals.

Is the parking brake spring pre-loaded in the unit?

Yes, the internal spring comes pre-loaded from the factory. Proper safety procedures must be followed during installation—never disassemble the spring chamber without using the correct mechanical release tools, as the stored energy in the spring can cause serious injury.
