Start with every identifier you already have

A number used by a distributor, rebuilder or another aftermarket catalog may still help locate a candidate kit even when it is not an OE number. Treat it as a cross-reference for identification, not proof of fitment.

  • Existing aftermarket reference
  • Vehicle make, model, year and market
  • Front or rear caliper
  • Left or right side if relevant
  • Caliper manufacturer or casting marks
  • Photos of the old kit and caliper

Photograph the complete kit clearly

Place every component on a clean background and photograph it directly from above. Add close views of seals, boots and unusual profiles. A ruler or caliper gauge should be visible when dimensions are important.

  • One full-kit photo
  • Piston and seal close-up
  • Guide boot profile
  • Bleeder screw and small caps
  • Any mechanical rear-caliper component
  • Package label only when you are permitted to share it

Measure the parts that control sealing and movement

For hydraulic parts, diameter and groove compatibility matter more than a general visual match. For guide-pin kits, pin diameter, working length, boot seats and bolt design should be compared.

  • Piston outside diameter and height
  • Square seal inside and outside dimensions
  • Dust-boot inner and outer seating profile
  • Guide-pin diameter and length
  • Thread size and pitch
  • Boot and bushing dimensions

Use a physical sample when the risk is high

A sample is recommended when the application is unconfirmed, the kit contains many rear-caliper mechanism parts, or previous leakage and fitment problems have occurred. The supplier can compare dimensions and kit contents before quotation.

What Shibao asks buyers to send

Shibao accepts a reference number, product photo, dimensions or physical sample for matching. Vehicle application and OE information are not published as confirmed facts until verification is complete.
