　　盤(pan)式(shi)制動器的檢(jian)修

　　1 用百分(fen)表檢測制(zhi)動盤的(de)斷面(mian)跳動誤差大(da)于0.06mm,制(zhi)動盤表面(mian)具有(you)明(ming)顯(xian)的(de)磨損臺階及拉傷溝槽(cao),可進(jin)行加工修(xiu)復.

　　2 檢查制動盤的磨損(sun)極限厚度(du)為8mm,厚度(du)過小(xiao)時應換(huan)用新件.

　　3 檢(jian)查制動(dong)蹄摩(mo)擦片(pian)(pian)厚度(du)小于7mm(包括底板)時,必須更換(huan)摩(mo)擦片(pian)(pian),且左,右輪必須成套(tao)更換(huan)(4片(pian)(pian)摩(mo)擦片(pian)(pian),4片(pian)(pian)彈簧片(pian)(pian)).

　　4 檢查制動鉗體,若發現有漏(lou)油之(zhi)處(chu),應換用新的(de)活塞密封圈.
