| Zusammenfassung: | The invention provides a drum brake friction plate abrasion display device. The drum brake friction plate abrasion display device comprises a fixation mark, an initial installation mark and an abrasion limit mark, wherein the fixation mark is arranged on a camshaft bracket of a brake, the initial installation mark and the abrasion limit mark are arranged on the camshaft of the brake, the fixation mark and the initial installation mark are located in the same plane during installation of the camshaft, and the abrasion limit mark and the fixation mark are located in the same plane when a brake friction plate is abraded to an outer end surface of a head portion of a rivet. The drum brake friction plate abrasion display device has the advantages that the drum brake friction plate abrasion display device is convenient to use and capable of accurately displaying rotation angles of the camshaft, namely, the abrasion degree of the friction plate; when the friction plate is abraded to the outer end surface of the head |
