About the Honda CM400C
Clutch and brake repairs for the 1981 CM400 Custom.
The CM400C Custom uses Honda’s air-cooled 395 cc parallel twin and a manual-clutch drivetrain. Its factory service information includes C-specific front suspension and brake details. That makes a complete Custom fitment important when comparing it with the more widely shared A, E and T service parts.
A focused clutch and brake repair list
Friction plates, steel plates and springs can be separately for the 1981 C. For the brakes, distinguish rear shoe replacement from work on the front handlebar master cylinder. Carburetor and fork kits need their own confirmed C fitment rather than a nearby CM400 model match.
Model and year comparisonCM400C parts differences
Manual-clutch components
The friction plate, steel plate and spring kit each fit CM400C 1981. Check package quantities separately.
Front brake hydraulics
The 1981 C kit repairs the handlebar master cylinder. Caliper seals, pistons and pads need their own application.
Fork and carburetor details
Retain the C suffix and compare markings. Neighboring CM400 models are not a substitute for a confirmed C part.
