Product Overview
Brake drag, uneven pad wear and leakage around the piston or bleeder are common reasons to replace a caliper. Flush contaminated fluid and inspect hoses, rotors and master-cylinder operation during the repair.
Polaris parts diagrams identify 1912277 as the left-hand rear caliper and 1912278 as the right-hand rear caliper. Fitment spans multiple UTV platforms, so part-number verification is the safest check.
