Tools and Parts Needed - Polaris Sportsman Brake Pad Change

Tools

  • Ratchet and 15mm socket
  • 5mm Allen
  • Flathead screwdriver

NOTE: The Polaris brake pad kits contains 2 brake pads, and you'll need a separate kit for each wheel. The front and rear brake pads are identical on the Sportsman 850XP, so this Polaris brake pad kit is compatible with either wheel.

Replacing Polaris Sportsman 850XP Front Brake Pads

Step 1. Remove the wheel.

Step 2. Compress the brake piston back into the caliper by inserting a flathead screwdriver between the caliper and the outer brake pad, and levering against the caliper.

NOTE: The piston must be compressed into the caliper so there is enough room to fit the new brake pads over the brake disc.

Step 3. Remove the 5mm Allen cap at the rear of the caliper, followed by the two 15mm brake caliper mounting bolts, and then slide the caliper assembly off the brake disc.
