New hydraulic disc brake calipers for the front axle, compatible with 150cc, 200cc and 250cc ATVs/Quads, universal upgrade kit for the lower front brake cylinder.

Universal compatibility for medium and large displacement engines: This product is specifically designed for 150cc, 200cc, and 250cc quads, ATVs, and UTVs, providing braking performance and heat dissipation optimized for these engine sizes. Improved front brake system: As an actuator (lower pump) for the front wheel's hydraulic disc brake system, this product is designed as a direct replacement for stock calipers with insufficient braking performance, stuck pistons, or damaged calipers. It significantly improves front wheel braking performance and serves as a key component for brake system upgrades. Guaranteed high-performance braking: Typically equipped with one or two opposing pistons, it provides ample and consistent braking force. When used with heavy-duty brake pads, it ensures stable and reliable braking on any terrain, including beaches and dirt roads. Ready-to-install kit: This product is a complete brake caliper assembly, typically including the caliper body, piston, dust cap, brake pads, and mounting bolts. No additional parts are required, making installation quick and easy.
