It is an individual sealing-support component used in the brake-piston arrangement, not a full brake repair kit or a standard O-ring. The correct component must be selected by exact part number and installation position because the rear brake assembly contains several different seals and backup rings. During overhaul work, confirm the truck serial number, rear brake parts diagram, and all associated seal references before ordering. Ruijueparts supports part-number lookup and multi-item sourcing for mining-truck brake service.\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003c!--TgQPHd||[]--\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"Fsg96\"\u003e\u003c!--TgQPHd||[]--\u003e\u003c\/div\u003e\n\u003ch2 id=\"s0-2-1-25-5-20-1-101[1]-2-3-7[0]-4[0]-3[0]-11[1]-1-5-title\" class=\"section-title__title\"\u003e\u003cspan class=\"ux-layout-section-module-evo__title\"\u003e\u003cspan class=\"ux-textspans\"\u003eItem specifics\u003c\/span\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable width=\"100%\" style=\"width: 100.088%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003ePart Number:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e561-33-71550, 5613371550\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eFits Models:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eHD785-7\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eBrand:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eKomatsu replacement\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eType:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eBrake Backup Ring\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003eSystem: Rear wheel \/ rear axle final brake sealing assembly.\u003cbr\u003eFunction: Supports the specified sealing element within the rear brake-piston arrangement.\u003cbr\u003eEquipment: Selected Komatsu HD785-7 rigid mining dump trucks.\u003cbr\u003eVerification required: Confirm truck serial number, rear brake parts diagram, and exact part reference before ordering.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRigid Mining Dump Truck: HD785-7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.7188%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eSize:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.8534%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eStandard Size\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eFAQ\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e1.
