Product Details

The Cardone Unloaded Caliper w/Bracket line focuses on remanufactured brake hydraulics built to OE specifications. Part number 19-B2858 is remanufactured from an original equipment core, then updated with new EPDM rubber seals, durable piston components, and corrosion-resistant finishing to help maintain proper brake function. For Mazda 6 rear brake service, this caliper assembly provides the correct mounting bracket and hardware kit for a cleaner replacement process.

This part cross-references Mazda GKYA2699ZB and GKYA2699ZC for the same application.

Common Brake Issues It Can Address

  • Brake drag from a sticking rear caliper
  • Uneven rear braking on the Mazda 6
  • Leaking caliper seals or damaged bleeder threads
  • Corrosion on the caliper body or piston area
  • Poor brake pedal response caused by caliper wear

Installation Notes and Tips

Fits 2003-2005 Mazda 6, rear left. Confirm the inlet port size is M10x1.0 and the bleeder port size is M7x1.0 before installation. Use the brake fluid specified by the vehicle manufacturer, and bleed the system thoroughly after replacement. Floating caliper pins should be lubricated with silicone grease, and all brake connections should be checked for leaks after service. Part number 19-B2858 is supplied as an unloaded caliper, so brake pads are not included.

Quality Assurance

Cardone remanufactures this caliper to rigorous quality and performance standards, then pressure-tests each unit before release. The process uses new premium components and reduces energy and raw material use compared with manufacturing a new part.
