Description
What does an ALB valve repair kit do?
This repair kit is designed to overhaul the internal components of an Automatic Load Sensing (ALB) valve, which regulates brake pressure based on axle load. By replacing the internal wearing elements, the valve can accurately graduate air pressure sent to the brake chambers, ensuring braking performance remains proportional to the load of the vehicle.Compatible vehicles and systems
The kit is compatible with WABCO systems and is used in heavy commercial vehicles including Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. These components help maintain stability by preventing wheel lock-up or trailer sway during varying load conditions.Installation and maintenance
A technician should inspect the diaphragm, piston, O-ring set, seal, spring assembly, and control pin during routine brake system maintenance. Replacing these high-strength components can restore the valve to factory-level tolerances without requiring a full valve replacement. Check the compatibility list for specific fitment details.Troubleshooting and maintenance
Regular inspection of the ALB valve ensures that the pneumatic signal from the suspension is correctly translated into brake pressure. If the braking force feels inconsistent during heavy loads or empty runs, renewing the internal seals and piston assembly is a recommended maintenance step.OE cross-reference
303.06.0001.01 (ALB Load Sensing Valve Repair Kit) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 4757109002.Other OEMs
