Vehicle piston clearance adjustment in tandem master brake cylinder - involves shimming of pressure member into bore of driving piston after correct positioning of floating piston

摘要

The floating piston (10) is fitted with two cuffs (11,12) similar to the sealing cuff (14) of the driving piston (13). The distance between the equalising ports (7,8) is measured together with the distance from the edge of the forward cuff (11) to the end of the floating piston (10). The difference is calculated and adjusted before the assembly is moved so that the forward port (7) is closed. The distance (M2) of the end (19) of the bore (22) is subtracted from the set-point value (S). ADVANTAGE - Very tight clearances can be secured with single assembly of all internal components.
