Description
What does an ALB repair kit do?
This repair kit is designed to overhaul the internal components of an ALB load sensing valve, ensuring the pneumatic braking system maintains precise pressure regulation. By replacing the internal wearing elements, technicians can restore the valve's ability to graduate brake force proportional to the axle load, which is critical for preventing wheel lock-up and maintaining stability.Compatible vehicles and systems
The kit is engineered for use in heavy commercial vehicles, including Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. It is also compatible with Wabco and Knorr-Bremse systems. These components ensure that braking performance remains consistent whether the vehicle is carrying a full load or traveling empty.Maintenance and installation
For efficient maintenance, technicians should inspect the diaphragm, piston, and seal set during routine brake system servicing. Replacing these high-wear components—including the spring assembly and control pin—is an economical solution to prevent system degradation. Check the compatibility list for detailed fitment information.Troubleshooting and selection
Regular inspection of the ALB valve assembly helps prevent uneven braking force across axles.FAQ
What components are included in the repair kit?
The kit typically contains a diaphragm, piston, O-ring and seal set, spring assembly, and a control pin to restore the valve's internal function.
Which systems are these kits compatible with?
These kits are designed to be compatible with Wabco and Knorr-Bremse type ALB load sensing valves used in heavy commercial vehicles.
Can this kit fix uneven braking?
Yes, by replacing worn seals and diaphragms, the kit restores the valve's ability to regulate brake pressure according to axle load.
When should I replace the ALB valve seals?
Replacement is recommended when there is a loss in pressure regulation capability or visible wear on the internal diaphragm and seals.
