PCT No. PCT/EP92/00955 Sec. 371 Date Feb. 19, 1993 Sec. 102(e) Date Feb. 19, 1993 PCT Filed May 2, 1992 PCT Pub. No. WO93/00237 PCT Pub. Date Jan. 7, 1993.The invention relates to a load-sensitive twin brake power controller whose change-over pressure is determined by a lever through a rocking element. The housing is extruded. Traditionally, a large-volume cylindrical chamber for the accommodation of the rocking element and a circular dust cover seat are mill cut into the housing. Such a loss of material is avoided by the present invention in that in conjunction with the extruded profile section two housing projections are molded which are each provided with one groove. Between the latter the dust cover is pressed with a sheet metal ring against the housing until the sheet metal ring comes to be locked in the grooves.
