1976 Honda CB550F · Front caliper service Buying guide

Inspect the caliper body before choosing the repair scope

Use the original caliper reference and removed piston to identify the replacement. Keep the piston, hydraulic sealing ring, adjuster hardware and protective bleed cap distinct when planning an individual-parts rebuild.

Compare the internal parts with the removed assembly

The separate piston and ring replace different references and are ordered individually as products. Compare their application with the fitted front caliper, especially after a front-end change. Inspect the body before rebuilding: replacement internals cannot repair stripped threads or a damaged hydraulic sealing surface.

Allow for assembly and supporting hardware

The complete replacement includes the main listed components, but may need final assembly before installation. The linked caliper adjuster contains its bolt, spring, washer and nut; the separate mounting set contains two bolts and two washers. Confirm the existing hardware arrangement and complete the brake service using the Honda manual.

Front Brake Caliper Parts FAQs

Is the piston supplied with a new hydraulic sealing ring?

The featured piston and sealing ring are separate products. Match piston reference 45107-323-020 and ring reference 45108-300-003 to the fitted caliper, then order the required service pieces rather than assuming they form one kit.

Does the replacement caliper need final assembly?

It may require final assembly. The package lists the body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. Have the assembly correctly completed, installed, inspected and bled; its supplied contents do not replace the full brake service procedure.

What should I check before replacing the bleed screw?

Confirm the installed caliper and replacement reference 45224-579-013, then inspect the body threads and screw seat. A new screw will not repair damage in those locations. The bleed cap protects the screw externally and is a separate type of component.
