The foundation of safe and reliable heavy-duty vehicle operation lies in a responsive and powerful air brake system. The genuine 1314020472A023 Rear Brake Chambers from SANY are critical actuators designed to convert air pressure into the mechanical force needed to engage the rear brake shoes. As an essential and safety-focused SANY parts, this complete set ensures balanced and synchronized braking force across the rear axle. The OEM chamber set 1314020472A023 is engineered for durability, consistent performance, and resistance to harsh environmental conditions, providing the dependable stopping power required for fully loaded SANY trucks in demanding applications.

In an air brake system, the brake chamber is the final and crucial component that initiates physical braking. When the driver presses the brake pedal, compressed air is routed to the rear brake chambers, specifically identified by part number 1314020472A023. This pressurized air enters the chamber and acts upon a flexible rubber diaphragm. The diaphragm, constrained by a heavy-duty metal housing, expands forcefully, pushing against a pressure plate connected to a pushrod.
This linear motion of the pushrod is then transferred through the slack adjuster to rotate the brake camshaft. The rotation of the camshaft forces the brake shoes apart and against the inner surface of the brake drum, creating the friction necessary to slow or stop the vehicle. The set 1314020472A023 ensures that both rear wheels receive identical and simultaneous actuation force, which is vital for maintaining vehicle stability and preventing uneven brake wear or dangerous pulling during braking maneuvers. Their reliable operation is non-negotiable for vehicle safety.
The SANY Rear Brake Chamber 1314020472A023 is built to endure the constant pressure cycles, road vibrations, and exposure to elements typical in heavy trucking. The main housing is typically constructed from two stamped steel halves that are crimped or bolted together to form a sealed unit. This design must be robust enough to contain high air pressure without deformation. The internal diaphragm is made from a multi-ply, reinforced synthetic rubber compound, engineered for exceptional flexibility, tear resistance, and longevity despite millions of expansion and contraction cycles.
The design is compact yet powerful, delivering a specific stroke length and force output that is precisely matched to the braking requirements of the SANY vehicle’s rear axle. Using the correctly sized and spec-matched genuine chamber, such as 1314020472A023, is critical for maintaining proper brake balance and compliance with vehicle safety regulations.

Replacing rear brake chambers with the 1314020472A023 set is a precise task that directly impacts braking safety. Before starting, the vehicle’s air system must be fully depressurized by draining the air tanks. The old chamber is disconnected by removing the air supply line and unbolting it from its mounting bracket on the axle. The clevis pin connecting the chamber’s pushrod to the slack adjuster must also be removed.
The new chamber from the 1314020472A023 set is positioned on the bracket. It is crucial to ensure the pushrod is at the correct angle and length to connect properly to the slack adjuster without binding. The chamber is bolted securely to the bracket, the air line is reconnected, and the clevis pin is installed with a new cotter pin for safety. After installation, the air system must be re-pressurized and checked thoroughly for leaks using a soapy water solution. Finally, the brake adjustment must be checked and set correctly to ensure the chamber’s stroke is within the legal and operational limits.
A failing brake chamber exhibits clear warning signs. A loud, continuous air leak heard near the wheel when the brakes are applied (or sometimes when released) often indicates a torn or ruptured diaphragm, which is a severe failure for component 1314020472A023. Reduced braking power on one side of the axle, causing the vehicle to pull during braking, can point to a chamber that is not generating full force due to an internal fault or external leak.
Visible damage to the housing, such as deep dents or cracks, compromises the chamber’s integrity. During routine maintenance, it is imperative to check the chamber’s stroke length with a ruler while an assistant applies the brakes. Stroke beyond the manufacturer’s specification indicates excessive wear in the foundation brakes or a malfunctioning automatic slack adjuster, causing the chamber to overstroke, which can lead to diaphragm fatigue and failure. Regular visual inspection for external corrosion, damaged air lines, and secure mounting is a key part of preventative maintenance for the brake system utilizing chambers like 1314020472A023.
Supplied as a matched set, the two chambers in 1314020472A023 are guaranteed to have identical performance characteristics. This ensures equal force output to both rear wheels, which is fundamental for straight-line stopping stability, preventing jackknife scenarios, and ensuring even brake lining wear.
Manufactured with precision seals and a high-quality diaphragm, the genuine chamber maintains a perfect air seal over its service life. This reliability ensures immediate and full brake application force is available every time the pedal is pressed, a critical safety factor that inferior chambers may not guarantee.
The corrosion-resistant housing and robust internal components of the 1314020472A023 are built to withstand vibration, moisture, and road debris. This results in a longer service life and reduced risk of unexpected failure compared to non-OEM alternatives, providing greater operational uptime and safety.
The SANY Rear Brake Chambers, provided as set 1314020472A023, are not just replacement parts; they are vital safety components that form the critical link between the driver’s command and the vehicle’s stopping power. Their consistent and reliable performance is a cornerstone of commercial vehicle safety, impacting not only the driver but also other road users. A compromised brake chamber directly compromises the entire braking system’s effectiveness.
Therefore, choosing the genuine OEM set 1314020472A023 for maintenance or repair is a decision that prioritizes compliance with safety standards, vehicle reliability, and peace of mind. It ensures perfect compatibility, dependable performance, and the durability required for the severe demands of heavy transport. For fleet managers and technicians committed to the highest safety standards, this chamber set is the definitive and responsible choice for maintaining optimal rear brake system integrity.
Brake system work, including chamber replacement using set 1314020472A023, must be performed by qualified personnel. Always fully depressurize the air system before beginning work. Never attempt to repair a damaged brake chamber diaphragm; always replace the unit or the service kit with genuine parts. After installation, a full brake system check, including stroke measurement and a dynamic brake test, is mandatory to ensure safe operation. Regular inspection and maintenance of the entire air brake system, as per the manufacturer’s schedule and DOT regulations, are required by law and are essential for safe vehicle operation.
