Description
What does an ALB repair kit do?
This repair kit is engineered to restore the functionality of the automatic load sensing (ALB) valve, which is critical for regulating brake pressure according to axle load. By replacing the internal wearing elements, technicians can ensure that braking force remains proportional to the load, preventing wheel lock-up and maintaining stability during heavy-duty operations.Compatible vehicles and systems
The kit is compatible with WABCO and Knorr-Bremse type ALB load sensing valves used in Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks heavy commercial vehicles. These components ensure the pneumatic signal from the suspension is correctly translated into graduated air pressure for the rear-axle brake chambers.Maintenance and installation
To maintain optimal braking performance, it is recommended to inspect the diaphragm, piston, and seals during routine pneumatic system maintenance. Replacing these internal parts with a high-strength component kit is a precise way to restore valve tolerances without replacing the entire assembly. Check the compatibility list.Troubleshooting guidance
Proper installation ensures the spring assembly and control pin work in harmony with the piston to prevent uneven braking force across axles.FAQ
What components are included in this repair kit?
The kit includes the essential internal elements: a diaphragm, piston, O-ring and seal set, spring assembly, and a control pin to restore valve function.
Which systems is this kit compatible with?
This kit is designed for WABCO and Knorr-Bremse type ALB load sensing valves used in various heavy commercial vehicles.
What are the symptoms of a worn ALB valve?
Worn components can lead to improper brake pressure graduation, potentially causing wheel lock-up or instability depending on the axle load.
Is it better to replace the whole valve or use a repair kit?
Renewing the internal parts like the diaphragm and seals is often a highly efficient way to restore factory tolerances more economically than replacing the entire unit.
