🔧 Product Highlights

• Complete Set of 2 — Left and Right Master Brake Cylinders: This listing includes 2 master brake cylinders (left + right) — the complete pair required for a full brake system restoration on Case 580 / 590 / 570 / 585G–588G applications. Replacing both cylinders simultaneously ensures balanced braking performance and eliminates the risk of one-sided brake pull on the worksite
• Direct OEM Replacement: Built to match the original Case 182445A1 / D143162 / D141150 specifications — ensuring proper bore size, seal compatibility, and hydraulic pressure output for the Case 580 / 590 / 570 series brake system
• Case 580 Series — The World’s Most Widely Used Backhoe Loader Lineup: The Case 580 series (580K / 580L / 580M / 580SL / 580SM) is one of the most widely used and trusted backhoe loader lineups in the world — deployed by contractors, municipalities, utilities, and rental fleets globally for excavation, trenching, grading, and material handling. The Case 580 has been the backbone of the global construction and infrastructure industry for decades
• Case 590 Series — Case’s Extended-Reach Backhoe Loader: The Case 590 series (590SL / 590SM) is Case’s extended-reach backhoe loader — trusted by contractors for deeper digging and greater versatility on demanding construction sites
• Master Brake Cylinder Failure — A Safety-Critical Issue on Heavy Construction Equipment: A failed or leaking master brake cylinder causes spongy brakes, reduced stopping power, brake fluid leaks, and potential complete brake failure on heavy construction equipment. On a backhoe loader operating on slopes, near trenches, or around workers, brake failure is a serious safety hazard. Immediate replacement is essential
• Case 585G / 586G / 588G — Case’s Heavy-Duty Rough-Terrain Forklifts: The Case 585G, 586G, and 588G are Case’s heavy-duty rough-terrain forklifts — trusted for material handling on construction sites, lumberyards, and agricultural operations
• Restores Full Brake System Performance: Corrects spongy brakes, brake fluid leaks, reduced stopping power, and brake imbalance caused by worn or failed master brake cylinders on all compatible Case 580 / 590 / 570 / 585G–588G equipment
