  • Weight: 10.30 lbs (4.67 kg)
  • Type: Brake piston — Carraro rear axle
  • Carraro DPN: 141259
  • Application: Brake piston — applies hydraulic pressure to the brake disc assembly in the Carraro rear axle, engaging the disc brake system to slow, stop, or hold the machine on applicable Cat 424B backhoe loaders
  • Note: Confirm your machine's serial number and axle configuration before ordering
  • Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when brake performance is reduced or inconsistent, the machine is not holding position on a grade, the brake piston is leaking hydraulic fluid, or the piston bore is worn and causing brake drag or incomplete release — a failed brake piston prevents reliable hydraulic brake engagement in the Carraro rear axle disc brake system on applicable Cat backhoe loaders.
