Brake Bias bars setup
Morning all (techinically afternoon i know)
I was just having a look at my brake setup. it's using a bias bar like the one shown below
I'm abit concerned as i think the bar could slip and move out of place, and there doesn't appear to be a circluip to hold it in place.
admittedly it only goes in from one side and has a fairly good friction fit in the middle but does appear to move out with a gentle tap (the bearing
to the holder), also how have people locked it off to pass SVA? can a couple of Nyloc nuts be used? one each end of the bar?
any comment will be much appriciated.
best regards

Generally, well in our setup and I think others, the bar is allowed to move along the tube. It is retained in the tube by the joints to each master
cylinder fitting fairly closely to each end of the tube. As you turn the bar it moves along the tube to give the differing bias. Not, as i think you
believe, the bar staying fixed in the tube and the joints moving along the bar when rotated.
Hope this makes sense!

When fitted the two screwed yokes which connect to the cylinder operating rods will be pretty much up against the central tube in the brake pedal
unless your cylinders are unusually far apart. This prevents the bar moving. Rally design catalogue and has a lot of useful information and drawings
on this in their tech tips.Here

Hi and dont forget that the bar will need some form of locking to stop itself from turning and altering bias as you go.
Altho i would think that that was coverd on the sva anyhow.

That was another of my questions how to do this?
is a couple of nyloc nuts one on each end ok?

Hi can be done by using a tube over the thread that will push up to the pivot and a lock nut up to the tube but make shure the tube dosnt catch the
outer part of the pivot if that makes sence.

Can having a bias adjuster on dash which is some how lockable suitable for the locking purposes?

I read in one of the magazines that it does suffice but obviously it depends upon the examiner interpretation of the rules...
