Product Introduction

This Rear Axle Brake Chamber, L=270 WG9000360600 is an OEM heavy-duty dual-diaphragm brake chamber, specifically designed for the rear axle brake system of Sinotruk heavy-duty trucks and commercial vehicles. Constructed with a high-strength steel housing and reinforced rubber diaphragms, it delivers reliable, consistent braking and parking force under heavy-load, long-haul, and harsh operating conditions.

Performance

• High-Strength Steel Housing: The rugged, gray-painted steel housing provides exceptional impact and vibration resistance, protecting internal components from damage in rough terrain and heavy-duty applications.

• Reinforced Dual Diaphragms: Heavy-duty, heat-resistant rubber diaphragms ensure consistent force output and long service life, even under repeated high-pressure cycling for both service and parking brake functions.

• Precision-Machined Components: The clevis, pushrod, and mounting hardware are precision-machined from high-grade steel, ensuring a secure fit and smooth operation with the brake linkage.

• Corrosion Resistance: The durable paint finish and zinc-plated hardware provide long-lasting protection against rust and corrosion, extending service life in all weather conditions.

Core Function

1. Converts compressed air pressure into mechanical force, actuating the brake linkage to apply the rear axle service brakes and providing spring-applied parking brake force—a core part of heavy duty truck brake parts.

2. Delivers consistent, reliable braking force to ensure responsive stopping performance under all operating conditions.

3. Withstands repeated mechanical stress and pressure fluctuations, maintaining reliable performance over millions of brake cycles.

Frequently Asked Questions (FAQ)

1. What exactly does the Rear Axle Brake Chamber WG9000360600 do?

This dual-diaphragm brake chamber converts compressed air pressure into mechanical force that pushes the brake shoes against the drum on the rear axle. Additionally, its integrated spring mechanism provides parking brake force when air pressure is released — keeping the truck securely stationary on inclines.

2. How do I know if WG9000360600 fits my truck?

This part is designed for Sinotruk HOWO, HOWO A7, T7H, and SITRAK models equipped with the standard rear axle drum brake system. To confirm compatibility, simply provide your vehicle’s chassis number or current part number, and our team will verify the match.

3. What is the stroke length “L=270” and why does it matter?

The “L=270” refers to the 270mm maximum push-rod stroke. This dimension determines how far the brake actuator can travel to fully engage the brake shoes. Using the correct stroke length is critical — too short means incomplete braking; too long can cause over-travel and component damage.

4. How long does this brake chamber typically last?

Under normal operating conditions and with proper maintenance, a quality rear axle brake chamber like the WG9000360600 can last 200,000–400,000 km. However, factors such as overloading, contaminated air supply, and extreme temperatures can shorten its lifespan. Regular inspection of diaphragm condition and air-tightness is recommended.

5. What are the signs that this brake chamber needs replacement?

Common indicators include: air leaks around the chamber body, sluggish or uneven rear braking response, the parking brake failing to hold on grades, visible cracks or swelling in the diaphragm (during inspection), and excessive push-rod travel beyond the adjustment range.

6. Is this an original Sinotruk part or aftermarket?

Mettlead supplies OEM-equivalent brake chambers manufactured to the same specifications and quality standards as the original factory parts. They are fully interchangeable with the genuine WG9000360600 and undergo strict quality control testing before shipment.

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

Absolutely. We offer white-label and custom packaging services. You can supply your own artwork and branding requirements, and we’ll package the product accordingly — ideal for distributors building their own aftermarket brand identity.
