REAR MASTER CYLINDER

Overview

Polaris disc brake systems are light weight, low maintenance and perform well in the conditions ATVs routinely
encounter. However, there are a few things to remember when replacing disc brake pads or performing brake system
service to ensure proper system function and maximum pad service life.
• Perform a brake burnishing procedure after installing new pads to maximize service life.
• Optional pads are available to suit conditions in your area. Select a pad to fit riding style and environment.
• Do not over-fill the master cylinder fluid reservoir.
• Make sure the brake lever and pedal returns freely and completely.
• Adjust stop pin on caliper (if applicable) after pad service.
• Check and adjust master cylinder reservoir fluid level after pad service.
• Make sure atmospheric vent on reservoir is unobstructed.
• Test for brake drag after any brake system service and investigate cause if brake drag is evident.
• Make sure caliper moves freely on guide pins (where applicable).
• Inspect caliper piston seals for foreign material that could prevent caliper pistons from returning freely.
