1977 Honda CB550F · Front caliper parts Buying guide

Decide what the front caliper repair needs

A piston and sealing ring address internal service, while the replacement assembly supplies the listed major components. Adjuster hardware and the bleed screw are separate choices; inspect those pieces alongside the caliper being repaired.

Compare the service parts with the removed caliper

The piston measures 38.15 mm in diameter and 34 mm in height, replacing 45107-323-020. The separate ring replaces 45108-300-003. Inspect the body and seal area as well as the piston before choosing these parts; a damaged body needs assessment beyond ordering a new piston and seal.

Account for assembly and supporting hardware

The featured replacement assembly includes the major pieces listed on its card but may need final assembly before fitting. The linked adjuster set supplies its bolt, spring, washer and nut; the linked caliper fastener set supplies two bolts and two washers. Compare what is retained and use the correct assembly, installation and bleeding procedure.

Front Brake Caliper Parts FAQs

Does the replacement caliper arrive fully prepared for installation?

It includes the body, pads, piston, piston rubber, bleed screw, bolts and bleed cap, but may require final assembly. It still needs correct installation and bleeding. Compare the supplied components and existing brake with the appropriate service information.

How do I compare a replacement piston with the old one?

The featured piston measures 38.15 mm in diameter and 34 mm in height and replaces 45107-323-020. Compare those details with the removed piston and caliper identity, especially after a brake conversion; consult the service procedure for fitting.

Does the caliper adjuster set supply the mounting bolts too?

The linked adjuster set contains an adjusting bolt, spring, washer and nut. The two-bolt-and-two-washer caliper fastener set is separate. Identify the pieces needing replacement rather than treating the adjuster hardware as a complete set of caliper mounting fasteners.
