JINGKE Hydraulic Brake Master Cylinder for 90–250cc Go-Kart & ATV — Aluminum Alloy, Direct-Fit Replacement

If your off-road vehicle or kart has a worn or leaking brake master cylinder, this JINGKE aluminum-alloy unit provides a straightforward upgrade or replacement. Built to match common mounting patterns and pedal bolt spacing found on many popular small-vehicle models, the kit arrives with the fasteners needed for installation. The design focuses on corrosion resistance, accurate fitment, and consistent hydraulic performance so you can return to the trail with confidence.

How will this master cylinder fit my specific kart or ATV model?

The JINGKE master cylinder is engineered to fit a wide range of small off-road vehicles, covering many 90cc through 250cc platforms. It matches common mounting bolt centers and pedal attachment spacing used by manufacturers referenced below, but you should compare dimensions with your original part before ordering.

• Compatible with 90cc, 110cc, 125cc, 150cc, 200cc, and 250cc vehicles.
• Works with many Sunl, BMS, Roketa, Kandi, Kazuma, and Kinroad models.
• Specific bolt spacings: brake pedal bolt 20mm, cylinder mounting bolt 60mm.
• Compare images and measurements to your current cylinder for a confident fit.

What materials and construction features ensure durability?

This master cylinder is made from a new aluminum alloy that balances light weight with resistance to rust and wear. The alloy housing and machined surfaces help maintain seal integrity under regular hydraulic pressures encountered in recreational use.

• Lightweight aluminum-alloy body for corrosion resistance.
• Precision-machined contact surfaces for reliable sealing.
• Includes hardware to replace worn or missing bolts and nuts.
• Designed for repeated pedal cycles typical of off-road riding.

What comes in the kit and how easy is installation?

The package includes the hydraulic brake master cylinder plus the accompanying bolts and nuts required for a standard swap; no additional specialty parts are provided. Basic mechanical skills and common hand tools are sufficient for most installations, though bleeding the brake lines and confirming leak-free operation are essential final steps.

• Full master cylinder unit with reservoir and mounting points.
• Included bolts and nuts for immediate installation.
• Typical install requires hand tools and brake-bleeding equipment.
• Follow vehicle service manual torque specs and safety checks.

How should I verify compatibility before buying?

Although the JINGKE unit covers many makes and models, visual and dimensional comparison is the best way to ensure correct fit. Review the supplied product images, note the mounting and pedal bolt spacing, and cross-check with your existing master cylinder.

• Compare the product photos to your current part’s shape and ports.
• Measure your pedal bolt spacing (20mm) and mounting spacing (60mm).
• Confirm fluid port location and hose fitting orientation match.
• Contact seller support if unsure about fitment details.

Who is this for: This replacement is aimed at owners and mechanics of small off-road karts, buggies, and ATVs — particularly riders of Sunl, BMS, Roketa, Kandi, Kazuma, Kinroad and similar brands — who need a durable, ready-to-install hydraulic master cylinder to restore braking performance. Choose this kit if you want an aluminum-alloy replacement with included hardware and compatibility across many 90cc–250cc platforms, but always verify dimensions and mounting points against your original component before purchasing.
