Restore reliable brake caliper performance with the All Balls Brake Caliper Piston Kit, manufacturer part number 18-9034 and vendor part number 21-89034. This precision-machined rebuild kit is manufactured from high-grade 304 stainless steel to provide durable service in demanding powersports braking applications. Stainless steel construction helps reduce thermal conductivity by up to 93% compared with aluminum, supporting consistent caliper operation under heat.
The All Balls 18-9034 kit replaces vulnerable original-equipment piston designs, including plastic composite pistons that can become brittle with age and chrome-plated steel or aluminum pistons that may corrode. The kit also eliminates failure-prone ceramic inserts found on some KTM applications. Each kit includes the piston or pistons needed to rebuild one brake caliper, helping simplify maintenance and caliper restoration.
Fitment includes select Polaris models: 2015-2016 Polaris Sportsman 570 SP, 2017 Polaris Sportsman X2 570 EPS, 2016 Polaris Sportsman Touring 570 EPS, 2016-2017 Polaris Sportsman 570 EPS, 2014-2015 Polaris Sportsman Touring 570, and 2005-2006 Polaris Scrambler 500 4X4. Verify the vehicle model, year, and caliper configuration before installation to ensure proper fit. The All Balls brand is recognized for replacement components designed to support dependable powersports service and repair.
