Vanlison rear brake caliper & master cylinder set for Polaris ATVs — OEM-fit, includes pads & banjos

Vanlison rear brake caliper and master cylinder set replaces worn brake components on compatible Polaris ATVs for reliable stopping power and straightforward installation.

If you need a full rear braking assembly that matches OEM fitment for a range of older Polaris models, this Vanlison kit includes the caliper, brake pads, banjos, and master cylinder so you can restore rear braking without hunting multiple parts. The components are built to OEM specifications with a precision alloy piston and complete mounting hardware for a direct replacement of several Polaris part numbers.

Which Polaris models and years does this kit fit?

This Vanlison set was designed to fit a variety of late-1990s and early-2000s Polaris ATVs, including Magnum, Scrambler, Trail Blazer, Trail Boss, Xpedition, Xplorer, and Sport models. It is intended as a replacement for specific OEM part numbers listed in the product details. Double-check your vehicle year and variant before ordering because a few high-duty or HDS variants are excluded.

• Compatible with Magnum 325 (2000–2001), Magnum 500 (1999–2001)
• Fits Scrambler 400/500 (1998–2004 ranges), Trail Blazer 250/400, Trail Boss 325/330
• Includes fitment for Xpedition 325/425 and Xplorer 250/400; also Sport 400 (1999)
• Not compatible with some 2001 HDS/high-duty specialty variants—verify your model code

How hard is it to install this rear caliper and master cylinder set?

The kit arrives with the caliper pre-loaded with pads, banjo fittings, and the exact mounting bracket, so installation is largely plug-and-play for mechanically experienced owners. Typical tasks include removing the old caliper, swapping brake lines with the supplied banjos, mounting the new assembly, then bleeding the system. If you’re comfortable with basic brake work, this reduces shop time and complexity.

• Caliper includes brake pads and bracket for direct mounting
• Banjo fittings included—reuses your existing brake line routing
• Bleed the brake circuit after installation to remove air
• Contact Vanlison support for installation help or questions

What are the construction and performance highlights of the components?

The caliper uses a precision alloy piston engineered to provide consistent hydraulic pressure and durable operation under typical ATV conditions. The master cylinder is built to match OEM dimensions, enabling predictable lever feel and proper fluid displacement. Both parts are aftermarket replacements manufactured to align with original specifications rather than being generic or universal pieces.

• Precision alloy piston for stable braking pressure
• OEM-spec master cylinder for correct lever travel
• Includes all necessary mounting hardware and banjos
• Aftermarket parts manufactured to OEM tolerances

What does the package include and what warranty is provided?

The shipment contains one rear brake caliper assembly and one rear brake master cylinder—everything needed to replace the rear hydraulic components on compatible models. Vanlison offers a 3-month warranty on this item; reach out to support if you encounter fitment or installation issues. Keep your proof of purchase and vehicle details handy when contacting service.
