Description
What does an ALB repair kit do?
This repair kit is designed to overhaul the ALB (automatic load sensing) valve, which regulates brake force in the pneumatic braking system of heavy commercial vehicles based on axle load. By replacing the internal wearing elements, the valve's ability to graduate air pressure remains proportional to the load, preventing wheel lock-up and instability.Vehicle and system compatibility
This component set is compatible with WABCO and Knorr-Bremse systems used in heavy commercial vehicles such as Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. It provides an efficient solution for maintaining braking performance across various heavy-duty applications.Installation and maintenance guidance
The kit includes a diaphragm, piston, O-ring and seal set, spring assembly, and control pin. When installing these high-strength components, technicians should ensure all ports are clear and seals are seated correctly to maintain factory-level pressure regulation. Check for uneven brake wear or trailer sway as symptoms that indicate a need for valve maintenance.Troubleshooting brake regulation
Regular inspection of the pneumatic signal path and internal seals helps prevent sudden pressure loss in the braking system.Related Products

FAQ
What components are included in the repair kit?
The kit contains essential wearing elements including the diaphragm, piston, O-ring and seal set, spring assembly, and control pin.
Which systems is this repair kit compatible with?
This kit is designed to be compatible with WABCO and Knorr-Bremse type ALB load sensing valves.
When should I replace the ALB valve seals?
If you notice uneven braking force or instability in the vehicle's pneumatic system, it may be time to replace the internal seals.
How does an ALB valve regulate braking force?
It uses a mechanical or pneumatic signal from the axle suspension to graduate air pressure sent to the rear-axle brake chambers.
