1976 Honda CB750A · Caliper Parts Buying guide

Compare a caliper rebuild with a complete replacement

The rebuild kit, separate piston and complete caliper cover different repair scopes. Identify the fitted 1976 CB750A caliper first. The complete replacement calls for the later single-disc style with 51 mm mounting spacing.

Compare the complete contents before adding loose parts

The rebuild kit supplies the sealing ring, two caliper bolts with washers, bleed screw and cap, and adjuster hardware. A piston and pads are not listed in that kit. The complete caliper includes both, so compare its contents before buying duplicate service pieces.

Use measurements to identify the replacement, not assess wear

The listed piston measures 42.8 mm in diameter by 34 mm long; the complete assembly requires 51 mm mounting spacing. These are product-identification details, not wear limits. Have the body condition and repairability assessed using the correct service information and qualified brake-service support.

Questions before ordering

Is a new piston part of the rebuild kit?

No piston is specified in the rebuild kit. Choose the separate 42.8 × 34 mm piston if inspection calls for replacement, or compare the complete caliper if the body also needs renewal.

What dimensions identify the featured piston?

The piston is 42.8 mm in diameter and 34 mm long, replacing Honda reference 45107-392-003. Compare both dimensions and the fitted caliper before selecting it for the repair.

Is the complete caliper genuine Honda or aftermarket?

It is an aftermarket assembly replacing Honda reference 45100-392-003, sold individually. Confirm the later single-disc style and 51 mm mounting spacing; the Honda reference does not identify its manufacturer.
