Description
What does an ALB repair kit do?
This repair kit is designed to overhaul the automatic load sensing (ALB) valve, which regulates brake force in the pneumatic braking system of heavy commercial vehicles. By replacing the internal components that undergo wear, technicians can restore the valve's ability to graduate brake pressure according to axle load back to factory tolerances.Vehicle and system compatibility
The kit is compatible with WABCO and Knorr-Bremse type ALB load sensing valves. It is also fitted to Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks heavy trucks. These components ensure that braking force remains proportional to the load, reducing the risk of wheel lock-up or instability during transit.Installation and maintenance
To ensure proper function, technicians should inspect the diaphragm, piston, O-ring set, seal, spring assembly, and control pin during installation. Maintaining these sealing elements helps prevent air leaks and ensures the mechanical signal from the axle suspension is accurately translated into pneumatic pressure for the brake chambers.System performance benefits
Regular inspection of the ALB valve assembly can prevent system failure. Replacing the internal components is a highly efficient way to maintain braking performance without replacing the entire valve unit. Check the compatibility list.Related Products

FAQ
What components are included in this repair kit?
The kit contains a diaphragm, piston, O-ring and seal set, spring assembly, and a control pin to restore internal valve functionality.
Which braking systems are compatible with this kit?
This kit is designed for use with WABCO and Knorr-Bremse type ALB load sensing valves found in heavy commercial vehicles.
Why is it necessary to replace the ALB valve seals?
Replacing worn seals helps maintain correct pneumatic pressure regulation based on axle load, preventing wheel lock-up or trailer sway.
Can this kit be used for all heavy vehicle brake valves?
This kit is specifically for ALB (Automatic Load Sensing) valves; it is not suitable for other types of pneumatic brake valves.
