1976 Honda CB360T · Front Caliper Parts Buying guide

Assess the caliper before choosing internal parts

The featured piston, sealing ring and bleed screw are separate service choices. A related complete caliper provides another option when the body or several components need replacement, subject to inspection and final assembly.

Choose components after inspecting the body

The replacement piston references 45107-323-020 and the separate ring references 45108-300-003. Their availability does not establish that the existing caliper is rebuildable. Have corrosion, sealing surfaces and damaged threads assessed before committing to a parts-only repair.

Read the assembly option as a parts package

The linked assembly includes a body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. It may require final assembly before installation. Compare it with the installed caliper and have the completed hydraulic system properly assembled, bled and checked.

Common buying questions

Does the replacement piston include its sealing ring?

The piston and sealing ring are listed as separate products here. Add the appropriate seal to the order when the repair requires it, rather than assuming it comes with the piston.

When should I consider the complete caliper?

Consider the linked assembly if the original body is damaged or multiple components need replacement. Have the old caliper assessed first; a fresh piston and seal cannot resolve every body or thread defect.

Is the caliper assembly ready to fit straight from the box?

It contains the main caliper components, but final assembly may be required. Inspect the package, compare the fitted arrangement and have installation and hydraulic checks completed correctly before riding.
