Pedal Box - Brake Bias Bar IVA Lock
daveb666 - 4/7/13 at 04:51 PM

Failed my IVA today because the tester wasn't happy with the nylocks on my bias bar. He suggested fitting split pins.

To confirm if I fit split pins where the red dots are

..should that be OK?

What else have other people done?

Wire locking is easiest, and mentioned in manual as acceptable.

I used roll pins and that was OK.

Sorry, not sure what wire locking is?

Drill a hole and put a piece of wire through essentially! Same as a split pin etc

You drill a small hole through the corner of a nut head, pass wire through it, twist it and lock it to a suitable point, in your case wire together a nut either side of the clevis. It means you don't have to drill through the threaded bar
I have wire locked my sump plug

A link to this guide was posted a while back which is pretty useful.

I have a spool of stainless lock wire, how much do you want?

daveb666 - 5/7/13 at 02:18 PM

I only needed enough to do that tbh mate, but I've already ordered it now. £9 for 30m on Ebay, so that should last my lifetime I think! haha

Don't those nuts you're using as spacers stop the bias bar from pivoting? I thought you'd need a thin 'tube' spacer to screw the lock-nut against. If it can't pivot freely, you've got no bias setting - it's just acting straight on the master cylinder by binding on the side of the clevis.

In an ideal world I would say yes but the bias bar is 7/16 and the clevis isn't much more so there is no room to put any sleeve in. Any sleeve would sit against the clevis shoulders much like the nuts. There is some slack in the nuts and the bearing is not fixed in the pedal so there is some side to side movement. As long as you keep it greased it should move fine.
