1980 Honda CB900C Custom · Caliper Repair Parts Buying guide

Inspect the caliper before choosing seals or pistons

Match the 1980 Custom caliper by year and brake position, then inspect its piston surfaces, seal grooves and sliding hardware. A seal kit cannot restore badly damaged metal parts.

Use the correct piston and kit

The 1980 front piston is 38.12 × 35.15 mm; the rear piston is 42.8 × 41 mm. The front kit serves two front calipers, while the rear kit is separate.

Rebuild the cause of sticking or leakage

Inspect the whole caliper rather than replacing seals blindly. Damaged pistons, corroded grooves and sticking sliding parts need attention. Confirm the kit contents and separately source any required pistons or hardware; do not assume a seal kit includes them.

Practical questions

Can fresh seals make a pitted piston serviceable?

No. A damaged working surface can damage the new seal or continue leaking. Inspect and measure the piston and caliper against the correct service information before deciding what can be reused.

Why does the brake still drag after pad replacement?

Sticking pistons or other hydraulic restrictions may remain. Check caliper movement and lever or pedal return, and diagnose the hydraulic system before replacing more friction material.

What should be checked before riding after a caliper rebuild?

Bleed the opened circuit, check for leaks and establish a firm lever or pedal. Confirm the brake applies and releases correctly. If it remains soft, leaks or binds, keep the motorcycle out of service until the fault is resolved.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
