Key Features
- Complete Dual-Side Overhaul: Includes both the left and right side calipers, ensuring even braking pressure and preventing the vehicle from "pulling" to one side during hard stops.
- Premium Aluminum Construction: Forged from high-quality aluminum to provide the perfect balance of strength and weight reduction, while naturally resisting rust and corrosion.
- Optimized Thermal Management: The aluminum body effectively dissipates heat generated during braking, reducing the risk of fluid boiling and brake fade on long rides.
- Precision Hydraulic Response: Engineered for a smooth, linear feel at the lever, allowing riders to modulate their speed accurately on technical trails or loose terrain.
- Direct Bolt-On Fit: Standardized 50mm mounting spacing and 10mm bolt holes make these calipers a "drop-in" replacement for the majority of Chinese-made youth ATVs and pit bikes.

Before ordering, compare your original part with the photos and check the caliper bolt spacing, brake hose length, master-cylinder bore, lever side, banjo fitting angle, drum/hub dimensions, and handlebar diameter. Recheck listed specs such as 50mm Spacing, Mounting Hole Spacing: 50mm (1.97"), Banjo Bolt Diameter: 10mm (0.39").
