Bromsrum

Bromsrum is a Swedish term used in automotive and rail engineering to refer to the space or enclosure where braking components are housed within a vehicle. The concept focuses on the physical volume that contains parts such as calipers, discs or drums, brake shoes, actuators, and the associated hydraulic or pneumatic lines, rather than the components themselves.

The word is formed from broms, meaning brake, and rum, meaning room or chamber. In Swedish maintenance manuals, engineering drawings, and spare-part catalogs, bromsrum serves as a generic label for the brake housing area. The exact scope of what is included in bromsrum can vary between manufacturers, vehicle types, and braking system designs.

In practice, the meaning of bromsrum can differ by context. For drum brake systems, bromsrum often denotes the housing behind the brake drum. In disc brake arrangements, it may refer to the hub or caliper mounting area. In pneumatic or hydraulic air-brake systems, bromsrum can describe the brake chamber or its immediate mounting enclosure. Because of these variations, the term is mainly used within Swedish-language technical literature and is sometimes translated into English as brake housing or brake chamber, depending on the specific design.
