BRAKE SYSTEM

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.

CAUTION
Use only DOT-approved brake fluid as an assembly aid
for all procedures described in this chapter to prevent
brake system contamination. DO NOT USE
LUBRICANTS OF ANY KIND FOR ASSEMBLY, AS
THEIR USE CAN CAUSE RUBBER COMPONENTS
TO SWELL.
