1981 Honda CB650 · Caliper Service Parts Buying guide
Build a caliper repair from inspected parts
The piston is specified at 42.8 mm diameter and 36.5 mm length. Its sealing ring and outer dust boot have separate references; choose each for its actual position and condition.
The selected piston is listed for the 1979–81 standard CB650. Compare the dimensions and reference 45107-425-003 with the fitted caliper. A replaced front end requires its own component identification before this application can be relied upon.
Check the surrounding rubber and hardware
The piston sealing ring and dust boot are separate choices, not an implied complete kit. Inspect the caliper, shaft boot and bleed fitting during dismantling. Use the appropriate service information for cleaning, inspection, assembly and brake-system checks.
Ordering questions
Are the seal and dust boot supplied with the piston?
The piston record does not say whether rubber parts are included. The separate sealing-ring product supplies one hydraulic seal, and the dust-boot product supplies one boot. Confirm the piston package before duplicating parts, then order for the inspected caliper.
Can the piston dust boot replace the hydraulic sealing ring?
No. The hydraulic sealing ring references 45215-533-004; the external piston dust boot references 45109-425-003. They are different components with separate listings, each supplied individually. Match the part and position rather than treating both as interchangeable rubber seals.
What if the caliper has been changed?
Identify the replacement caliper and compare its parts directly. The 1981 standard CB650 listing cannot establish the piston, seal or boot for an unknown aftermarket or transplanted brake assembly.
