Title:Vacuum Brake Hose
Issuing Committee:Automotive Brake And Steering Hose Standards Comm
Scope:The vacuum brake hose is intended for use in the power braking systems of vehicles or as connections on transmission lines in combinations of vehicles or systems thereof. For the purposes of clearly identifying hose classification and for specification simplification, vacuum brake hose is divided into two types: heavy-wall Type H, and light-wall Type L.
