Brake calipers as cores

Brake calipers are a growing reman segment. The cast housing lasts a vehicle lifetime; pistons, seals and guides wear. With the spread of the electric parking brake (EPB), the value of the cores rises because the actuator is part of the caliper.

Why this part is valuable as a core

Housing and carrier are cleaned, tested and re-coated. Pistons, seal kits, guide pins and bleed valves are renewed.

With EPB calipers the electric actuator is added. Complete cores with intact actuator are in corresponding demand.

What we buy

  • Floating calipers front and rear, cars and vans
  • Fixed calipers (multi-piston) for premium and sports vehicles
  • Brake calipers with electric parking brake (EPB)
  • Calipers with or without carrier

Typical failure causes that make a core valuable

  • Seized piston due to corrosion
  • Leaking piston seal, brake fluid loss
  • Stiff or seized guide pins
  • Defective EPB actuator, parking brake does not release

Acceptance criteria

  • Housing without cracks, threads not stripped
  • Piston present, may be seized
  • For EPB: actuator fitted, connector undamaged
  • Brake pads and carrier may be missing
  • Manufacturer or OE marking legible

Questions about this part

Do you accept seized brake calipers?

Yes. Seized pistons are the most common reason for replacement and are corrected during remanufacturing.

Do you buy EPB calipers with a defective actuator?

Yes, as long as the motor is fitted and the housing is intact.

How should brake calipers be packed?

Drained, ports capped, in mesh boxes or on pallets. We provide packaging material if required.
