1975 Honda CB360T · Front Caliper Parts Buying guide

Rebuild a sound caliper or replace the assembly

A piston and sealing ring suit component-level repairs. The replacement caliper supplies a broader group of parts, but still requires correct preparation, assembly and brake-system checks.

Make the condition check first

Inspect the caliper body before purchasing only a piston and seal. The replacement piston is specified at 38.15 mm diameter and 34 mm height. A damaged or incomplete body can change the decision toward the broader replacement assembly rather than a collection of separate internals.

Review the assembly and hardware

The replacement caliper includes body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. It may require final assembly. The linked fastener set separately contains two bolts and two washers; compare your needs before duplicating components in the order.

Ordering questions

What comes with the replacement caliper?

It includes the body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. Final assembly may be required, followed by correct installation, bleeding and brake-system inspection before use.

How do I check the replacement piston size?

Compare the fitted piston with the listed 38.15 mm diameter and 34 mm height, and reference 45107-323-020. A changed caliper should be identified independently of the motorcycle’s model tag.

Can I buy just the seal if the piston looks usable?

Inspect the piston surface, caliper body and sealing area before deciding. The ring is available separately, but a worn or damaged mating part can make a seal-only repair inappropriate.
