The Hand Brake Valve 500028944 is used in compatible heavy-duty trucks and commercial vehicles equipped with pneumatic braking systems.
The hand brake valve allows drivers to manually control the parking brake by directing compressed air within the brake circuit. It plays an important role in maintaining vehicle stability when parked, especially for heavy trucks, trailers, and vehicles operating on slopes or uneven surfaces.
A faulty hand brake valve may cause issues such as air leakage, delayed brake response, difficulty engaging or releasing the parking brake, or unstable brake holding performance.
During replacement, technicians should inspect the air lines, connectors, pressure system, and related brake components to ensure the entire pneumatic circuit functions correctly.

Hand Brake Valve 500028944 is a pneumatic brake control component used to manually operate parking brake functions in compatible commercial vehicles.
It controls compressed air flow within the braking system, allowing the driver to engage or release the parking brake.
Typical symptoms include air leakage, slow brake response, difficulty releasing the parking brake, abnormal valve operation, or insufficient brake holding force.
Yes. Since it controls parking brake operation, a malfunctioning valve may affect vehicle stability when parked or during specific braking operations.
No. Brake valves are application-specific. Vehicle model, pneumatic system design, port configuration, and pressure requirements must be confirmed before ordering.
Provide the 500028944 part number together with the vehicle model, brake system information, original valve photograph, air port details, or physical sample.
Yes. Bulk supply is available for truck parts distributors, wholesalers, brake repair workshops, fleet maintenance companies, and international importers.
For qualified OEM and high-volume projects, customization can be evaluated for valve structure, pressure requirements, port design, materials, and packaging.
Yes. An original sample helps verify dimensions, port configuration, mounting structure, sealing requirements, and operating characteristics.
The air lines, fittings, seals, pressure system, mounting brackets, and other pneumatic brake components should be checked during replacement.
Proper installation, clean compressed air supply, regular inspection, avoiding contamination, and maintaining correct system pressure can help improve durability.
Yes. Customer labels, individual packaging, branded cartons, product markings, and export packaging can be arranged according to project requirements.
Please provide 500028944, required quantity, vehicle model, brake system information, destination country, and packaging requirements. An original valve photograph, sample, or technical drawing is recommended for accurate matching.
