Rear Hydraulic Disc Brake System Caliper for ATV Quad - Reliable

In this review we test the Rear Hydraulic Disc Brake System Caliper for ATVs and quads to see who it suits and why it stands out. The bottom line: this is a practical upgrade for riders of Chinese-made 50cc to 250cc ATVs who need a ready-to-install left rear hand brake assembly with a long hydraulic cable and master cylinder. The kit ships with a caliper, brake pads, a 1450mm high compression hydraulic cable, a lever and master cylinder, and its precision castings make it a durable, serviceable option for recreational riders and small utility users.

Key Features

• Complete rear hand brake assembly: Arrives with a caliper, brake pads, lever and master cylinder so the left rear brake can be replaced or upgraded without sourcing extra parts.
• 1450mm hydraulic cable: The long high compression hydraulic cable gives flexibility for routing and fits a wide range of frame layouts on many small ATVs.
• Wide model fit: Designed to fit most Chinese-made ATV models from 50cc to 250cc, making it a convenient universal replacement for TaoTao, Buyang and similar machines.
• Durable construction: Precision castings promise solid mechanical strength and consistent braking performance under typical trail or utility use.
• Includes brake pads: Pads are included so installation can be completed immediately without an extra trip to buy components.
• Lifetime guarantee: The unconditional lifetime assurance reduces risk and supports long-term ownership confidence.

Who It's For

This assembly is best for owners of smaller ATVs and quads who need a straightforward left rear hydraulic brake replacement or an upgrade from mechanical systems. It suits hobby riders, backyard mechanics and small fleet operators who run models like TaoTao, Buyang, Coolsport, Kazuma or Roketa and want a plug-and-play kit that includes pads and a master cylinder.

Riders who should look elsewhere include those with non-Chinese custom frames or unusual brake geometries where precise fitment cannot be confirmed from the pictures and specs, and high-performance racers seeking premium billet components tuned for competition braking feel.
