製動器要求每個班次檢查一次，經常出現的問題有以下幾種：
 

1、 製(zhi)動(dong)力(li)矩(ju)逐(zhu)漸(jian)減(jian)小(xiao)，這(zhe)是(shi)由(you)於(yu)製(zhi)動(dong)帶(dai)磨(mo)損(sun)，主(zhu)彈(dan)簧(huang)逐(zhu)漸(jian)放(fang)鬆(song)或(huo)製(zhi)動(dong)架(jia)各(ge)鉸(jiao)點(dian)的(de)孔(kong)或(huo)軸(zhou)磨(mo)損(sun)過(guo)大(da)等(deng)原(yuan)因(yin)造(zao)成(cheng)的(de)，如(ru)果(guo)製(zhi)動(dong)帶(dai)磨(mo)損(sun)到(dao)原(yuan)厚(hou)度(du)的(de)一(yi)半(ban)時(shi)就(jiu)更(geng)換(huan)。銷(xiao)軸(zhou)的(de)磨(mo)損量超過原直徑的5%，橢圓度超過1㎜時要更換，孔的磨損量超過原孔徑5%時，可用鉸刀擴孔，並重新配製相應的銷軸用。如果孔磨損很大，可用擴孔後加套或焊糕點後再加工孔的辦法修複。
