T30/30 Four-Stud Flange DD Brake Chamber
This model uses a four-hole flange mounting design, with the four mounting bolts evenly arranged. Part number 925322005 corresponds to a specific axle mounting platform, with hole spacing precisely measured and reproduced for direct alignment during installation. As a dual-chamber product, it combines both service and parking brake functions, making it suitable for drive axles and other locations with higher brake reliability requirements. The four-hole fixing method also shows better fatigue resistance than a conventional two-hole structure during long-term heavy-duty transport.

Compared with a two-hole or three-hole structure, it provides more balanced load support under full-load and emergency-braking impact, reducing the risk of deformation from localized stress concentration on the flange; it can be installed by direct alignment without drilling additional holes.
Suitable for drive axles and other locations with high brake reliability requirements.
Mounting hole drawing confirmation service can be provided to wholesalers and repair chains with a clear axle platform fitment need, avoiding return and exchange costs from incorrect model selection.
