Description
Maintaining the precision of the pneumatic braking system is critical for heavy commercial vehicle safety and performance. This repair kit is engineered to overhaul the automatic load sensing (ALB) valve, which regulates brake force based on axle load signals to prevent wheel lock-up and instability.
The 303.06.0170.01 is the OE equivalent of the WABCO and Knorr-Bremse type ALB load sensing valve parts used in Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks systems. This kit provides a cost-effective solution to restore valve functionality without replacing the entire assembly.
Technicians should inspect the diaphragm, piston, and seal sets during installation to ensure correct spring assembly alignment and control pin seating. Regular maintenance of these components ensures that braking force remains proportional to the load, whether the vehicle is empty or fully loaded.
Replacing worn internal elements helps prevent uneven brake application across the axle, ensuring consistent performance under varying heavy-duty operating conditions.

FAQ
What does an ALB Load Sensing Valve repair kit include?
The kit contains essential wearing elements including the diaphragm, piston, O-ring and seal set, spring assembly, and control pin to restore valve function.
Which vehicle brands are compatible with this repair kit?
This kit is designed for heavy commercial vehicles from Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks.
What is the function of an ALB valve in a brake system?
The ALB valve senses axle load via mechanical or pneumatic signals and regulates air pressure sent to brake chambers to ensure proportional braking force.
When should the ALB valve components be replaced?
Replacement is recommended when sealing capability degrades or when the braking force no longer adjusts correctly according to the vehicle's axle load.
What OEM systems can this kit service?
This repair kit is compatible with WABCO and Knorr-Bremse type ALB load sensing valves.
