brake bias bar thread size/type

[martinlaw]

I need to put either a nyloc or locking nuts on my brake bais bar to stop it 'self adjusting'.

Does anyone know the size and thread type used?

Thanks,
Martin.

You need to talk to the factory as they have a special lock plate for them.
It will probably need to be adjusted then drilled and pinned to pass SVA/IVA.

Steve, Is this a new SVA requirement or has been for a while?

Whatever, would this not have been in the std kit, or is this one of those 'options'?

Hate to think I missed someting so fundamental for SVA?

cheers

it's an sva requirement that's always been there. If you have an adjustable brake bias bar, this must be locked off so that you cant adjust it. If you also have an adjuster, then the tester must not be able to see it.

The factory tend to mention it when you go for your safety check, pre sva.

As Dave said, it has always been a requirement.
SVA (and IVA) requires it to be locked in such a way that it cannot be unlocked again with normal workshop tools. They will require it to be locked then drilled and pinned.
If you are doing this for yourself then you will need to take great care to get the setting right before drilling it. The front brakes must lock before the rear so this is the adjustment you must achieve.

When I did the Dakar I drilled and pinned the brake compensating valve after it had passed the SVA brake test. Even though I was doing this whilst the tester wrote out the MAC he still wanted to inspect the pin before he handed over the paperwork.

once you get it adjusted cant you just replace the floating bar with a solid bar and washers/spacer to suit. lock this up with a couple of lock nuts and then it will be non adjustable.

later ononce you get home you could then replace the original balance bar?

That's what i want to do, but the thread looks very fine and none of my stock nuts fit hense asking what thread and size the bar is.

Does anyone know??
