1976 Honda CB400F Front Caliper Kit and Piston

Rebuild one caliper, replace the piston, or replace the whole assembly. Those are three different purchases. A bleed-cap pack that does not name the CB400F is not the kit.

1976 Honda CB400F · Brake Caliper Rebuild Kits, Caliper Pistons, Bleed Screws Buying guide

One caliper at a time

The kit is sold as one kit for one front caliper. The piston's 2mm lip faces the pad. The assembly includes its own pads, piston, seal, bleed screw, bolts, and bleed cap.

Parts to consider

Names the 1975-77 CB400F along with CB350F and CB550. It is not a pair of calipers.View part Honda CB Front Caliper Piston ~ Replaces 45107-323-020 Caliper piston, 38.15 x 34mmReplaces 45107-323-020.

The assembly is not only a CB400F part

The title also names CB350 and CB550, and the fitment includes this Supersport. Use it when the body is too far gone to rebuild. If the body is fine, the one-caliper kit or the 38.15mm piston is the smaller purchase. The kit does not include a new body.

Caps that skip this model

A pack of ten bleed-screw caps replaces 45108-425-003 and does not name the CB400F. Match 45108-300-003 if you only need the piston sealing ring, and confirm that ring's fitment line before you treat it as this caliper's seal.

Caliper questions

Does the kit rebuild both sides?

No. It is sold as one kit for one front caliper, and it names the 1975-77 CB400F. Buy a second kit only if you are rebuilding a second caliper.

Which way does the piston face?

The side with the 2mm outer lip faces the brake pad. The piston is 38.15mm in diameter and 34mm tall, replacing 45107-323-020.

What comes with the caliper assembly?

Body, pads, piston, piston rubber, bleed screw, bolts, and bleed cap. It replaces 45100-390-405 and names the 1975-77 CB400F among other models.
