About the Honda CB400T2

Front-caliper, intake and clutch repair choices for the disc-brake Hawk II.

Honda Motorcycle Logo

The CB400T2 is the Hawk II version of Honda’s early 400 twin. Its original front disc brake distinguishes it from the drum-brake Hawk I, even where both models share selected fuel-system and clutch parts.

Separate caliper guide hardware from hydraulic parts

The front shaft boots protect moving guide hardware; the piston and its hydraulic seals perform different jobs. This guide links T2 caliper components, then separates intake holders and carburetor kits for fuel-system work.

Choose the model and repairHawk II front-caliper components compared

1978–1979 Hawk II caliper repair choices
Component Function Confirmed supplied form
Hawk II front caliper shaft boots Protect the caliper guide/shaft area from dirt and moisture. Pack of four boots; not hydraulic piston seals.
Honda caliper piston listed for Hawk II Moves within the matching caliper bore. Genuine Honda piston, 38.1 × 38.1 mm, sold individually; seals are separate requirements.
Hawk II front caliper bleed screw Opens and closes the caliper bleed passage. Sold individually; match thread, length and seat style.

The Hawk I guide covers a different original front-brake arrangement.

Frame, engine & fitted componentsHonda CB400T2 identification checklist

Use these details to match your motorcycle and any replacement assemblies before ordering.

  1. Record the frame/VIN, T2 designation and model year, plus the engine number.
  2. Identify the fitted front disc, caliper and master cylinder; note any replacement front-end parts.
  3. Copy the carburetor body markings before choosing a rebuild kit.
  4. Check the tank’s fuel-tap mount and cap style; for clutch work, list steel plates, friction plates and springs separately.
Need help identifying your CB400T2?

Contact PartsNMore with clear photos of the frame/VIN, engine number and the part’s markings, plus any known component changes.

Honda CB400T2 parts questions

Do the Hawk II caliper shaft boots replace the piston seals?
No. The linked shaft boots protect caliper guide hardware and come in a pack of four. Hydraulic piston seals perform a different function and need their own application. Both the guide boots and piston should be inspected during caliper service.
Which caliper piston is shown for CB400T2 1978–1979?
The guide links a genuine Honda caliper piston with a stated 38.1 × 38.1 mm specification and explicit CB400T2 1978–1979 applications. It is sold individually. Match the installed caliper, piston diameter and length, and required seals before ordering.
Can I buy Hawk II intake holders separately from the carb kit?
Yes. The linked intake holder with rubber O-ring lists CB400T2 1978–1979 and is sold individually. It seals the intake connection to the engine. The separate carburetor rebuild kit does not establish that holders are included.
Are Hawk I and Hawk II front brake parts interchangeable?
Their original front-brake systems differ: the Hawk I uses a drum and the Hawk II a disc. Shared carburetor or clutch applications do not establish front-brake interchange. Use the identity of any replacement front end when selecting service parts.
