Rear Brake Master Cylinder for Polaris
This rear brake master cylinder is for Polaris Trail Blazer and Trail Boss 250 and 325 ATVs, controlling rear brake hydraulic pressure when the rear brake is applied.
Overview
This rear brake master cylinder is a hydraulic replacement for the rear brake system on Polaris Trail Blazer and Trail Boss 250 and 325 models. The rear brake master cylinder sends pressurized fluid to the rear caliper, so the rear wheel can be slowed and stopped. This rear brake master cylinder is used when the rear brake pedal becomes soft, leaks, or fails to return normally.
Built For Performance
- Generates the hydraulic pressure needed to push the rear caliper piston during braking
- Creates a sealed rear brake fluid circuit to maintain lever and pedal response
- Returns the hydraulic bore to a closed position through the master cylinder internal release action
- Provides the fluid displacement required to apply the rear brake caliper on trail and utility machines
- Replaces a leaking or seized rear master unit in the existing rear brake line
Fits These Machines
- for Polaris Trail Blazer 250
- for Polaris Trail Blazer 325
- for Polaris Trail Boss 250
- for Polaris Trail Boss 325
On-The-Job Use
- Replacing a rear master cylinder that fails to hold pressure during ATV brake service
- Repairing a rear brake fluid leak that leaves the rear brake pedal unresponsive
- Restoring rear brake pedal feel on trail solid machines with worn cylinder internals
- Servicing the rear brake circuit during routine ATV maintenance

Good To Know
Q: Will this Polaris rear brake master cylinder fit a Trail Boss 250? A: It is designed for the Polaris Trail Blazer and Trail Boss 250 and 325 rear brake circuit. Confirm the rear brake line fitting style and ATV serial number before ordering.
Q: What needs to be done after installing this rear master cylinder? A: The rear brake system must be bled to remove trapped air. After bleeding, the rear pedal should be firm and should hold the rear brake without sinking.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
