Description

Scania Foot Brake Valve 1942899 – Spare part

The Scania foot brake valve is the central command unit for your truck’s pneumatic braking system. It acts as the primary interface between the driver and the air brakes, regulating the flow of compressed air to the brake chambers to ensure immediate, modulated, and safe deceleration.

At Cascade Overseas General Trading, we supply 100% genuine Scania Foot Brake Valves (1942899) along with premium aftermarket options from DT Spare Parts (1.18907).

We also offer high-quality OEM-grade aftermarket parts from KTK Germany and Swedish Lorry Parts (SLP), ensuring reliable performance and global export standards. Whether you are maintaining a single vehicle or a large commercial fleet, our high-performance valves are engineered to withstand high-cycle operations in demanding environments.

Quick Technical Specifications

Why Is This Part Essential for Fleet Safety?

The foot brake valve does more than just “stop” the truck. It manages the balance between the front and rear circuits.

• Precision Modulation: Translates pedal force into exact air pressure signals.
• Durability: Built with high-grade alloys to prevent internal corrosion from moisture in the air lines.
• Interchangeability: Also replaces Scania Reference Nos: 1442938, 1793024, 1867518, and Knorr-Bremse K044696.

Troubleshooting: When to Replace Your Foot Brake Valve

Waiting for a complete failure is a major safety risk. Look for these “Table of Signs” to determine if your Scania 1942899 valve needs replacement:

Common Failure Symptoms

Technical Standards & System Integration

Compliance with Global Safety Standards

The Scania Foot Brake Valve is engineered to meet the most stringent international regulations for heavy vehicle safety.

• ECE R13 (Braking Regulation): This part complies with the UN Regulation No. 13, ensuring uniform performance for braking systems in category M, N, and O vehicles. This guarantees that the valve provides the necessary graduated braking required for heavy-duty Scania trucks.
• ISO 7638 Standards: While the foot brake valve is primarily pneumatic, it works in coordination with the electrical braking system. Compliance with ISO 7638 ensures that the pneumatic signals from the 1942899 valves are perfectly synced with the ABS/EBS power connectors, maintaining electronic stability during deceleration.

What else should you inspect when replacing a Scania brake valve?

The foot brake valve does not act alone. To ensure a complete and safe repair, it is essential to inspect the following related Air Brake System Components:

• Brake Chambers: These act as the final executors, converting the air pressure released by the 1942899 valve into mechanical force to engage the brake shoes or pads.
• Relay Valves: Because the foot brake valve is located at the front of the cab, Relay Valves are used to “speed up” the air delivery to the rear axles. They receive a signal from the foot valve and immediately dump high-pressure air from the Air Tanks to the rear chambers.
• ABS Modulator Valves: In modern Scania trucks, the air from the foot brake valve passes through ABS Modulator Valves. These valves prevent wheel lock-up by rapidly “pulsing” the air pressure if the sensors detect a skid.
• Air Tanks (Reservoirs): These are the storage vessels for the compressed air. The foot brake valve draws its supply from these tanks through Ports 11 and 12. If your tanks contain moisture or oil, it will cause the internal seals of the foot valve to fail prematurely.

Frequently Asked Questions 

Is the DT 1.18907 valve a direct fit for the Scania 1942899?

Yes. The DT Spare Parts 1.18907 is a high-quality aftermarket equivalent designed to match the original manufacturer’s dimensions, port configurations (7 ports), and operating pressure (12.5 bar).

How do I prevent my foot brake valve from sticking?

Sticking is often caused by moisture and sludge in the air system. Regularly replacing your Air Brake Dryer Cartridge is the most effective way to protect the internal seals of the foot brake valve from contamination.

Can a faulty foot brake valve cause the “Low Air” warning?

Absolutely. If the internal seals are damaged, the valve can leak large volumes of air back through the exhaust port whenever the pedal is depressed, causing a rapid drop in reservoir pressure and triggering dashboard alarms.

What is the difference between a foot brake valve and a treadle valve?

In heavy-duty trucking, they are the same thing. The “treadle valve” specifically refers to the pedal and valve assembly together, while “foot brake valve” describes the pneumatic component itself.
