The purpose of this study is to prevent the release of the return spring of the impact bar on the built-in disk brake in the parking brake.;The research includes a fixed nut of the fixed rod (11) on the camshaft (13) of the built-in elevator brake pad of the parking brake and a combined anti-skid rod return spring (19) between the parking rod (11).The return spring (19), which is combined with the outer covering of the fixing nut (33), has a flange (35) with a diameter larger than the diameter. On the internal disc brake of the parking brake characterized by the outer covering of the fixing nut (33), an anti falling device of the return spring of the waterproof rod is provided.;In the above study, a banner was formed by the nut used to fix the lever. With the start of the mooring rod, the return spring was pressed to suppress the phenomenon of the return spring leaving. As a result, accidents caused by parking brake failure can be prevented.
