Front Brake Disc - Torque Settings for Bolts

[element137]

Hi everyone , I have had a look at the Haynes manual, but cant see the torque values for the four bolts/nuts that pass through the  front wheel hub and front brake discs, also assume these are thread locked  - as standard , there is no retaining tab washers ? ( as per the rear sprocket nuts )

Might be worth checking the downloadable Honda workshop manual on this site.

My 400 has lock washers, a paired arrangement iirc.

Thanks - I could not find it in the workshop manual - and I have seen conflicted images reference the lock tab washers - some with - some without ?- not sure if it changed on model years ?

Got it - many thanks for that -

Actually looking at that service bulletin, it looks like CB350 had the lock tabs - 400 not fitted ?

Might be worth checking the 400 parts book.🤔

Correct, 400f uses flanged locknuts instead.

Considering the damage a bolt would do I’d be inclined to fit the tab washers myself or failing that some nyloc nuts

[exvalvesetdabbler]

You would need a longer bolt for extra tab washers or for a nyloc to have something to grip

Without the washer or flange in this case the existing bolt should be ok.

Whilst I agree that they are not cheap, for such a safety critical part, the genuine flange nuts are available.

[Oddjob]

Have they got the serrated flange Mick? If so loads available in stainless steel

[Skoti]

Nyloc nuts not really suitable for high temp use such as brake discs, metal lock nuts are more appropriate.

Better safe than sorry.

I'm only going by the pics on the DSS site, which shows them as being smooth, but, listed as genuine parts.
