Brake Bias Adjuster

[Jonny Rochester]

I am fairly certain the the front pipes are not connected to the rear ones in any way on the iron junction block. I got an AE86 one and cut it in half to prove this point.

However the early junction blocks (eg KE30 etc) have a sensor for a warning lamp in them, so there is some connection between front and rear.

The AE86 ones definately dont, as for a fair while i was using one as a T-piece after the PBR brass one cracked.

I was once told by a bloke in a fairly well known brake store that the Wilwood bias valves aren't legal for road use in Australia (I'm in Victoria) as they use tapered pipe threads where only the last few threads actually hold the brake line into the bias adjuster. He said that he only used parts that used Metric or AN type threads, like the Tilton/AP bias valves.


Has anyone ever heard of this?

I have not been able to find any legal information about it and I don't really know whether to believe the guy as he probably just wanted to sell the more expensive part. I do understand where he was coming from but just don't whether to believe if its illegal or not.

i wouldnt be stressing too much about it...

99.9% of modified cars are illegal one way or another...

if ur car is to the point that it needs a bias adjustor...that fair chance ur car is well beyond being a legal road car anyways...

[Andy San]

I'm pretty sure having adjustable bias is illegal anyway

[boh086]

I thought it was only illegal if you could adjust it from the driving position?

[Andy San]

Probably, I'm pretty sure 90% of the rules are debatable anyway

[s14seriesII]

technically anything other than standard parts is illegal, caliper brackets, and all the other aftermarket manufatured stuff is far from legal

[Tim.duncan]

just mount it where no one can see it..... then it will be legal. thats how it works right?

[ke70dave]

"legal" is a grey word

i was under the impression that you couldn't have adjustment from inside the car?

essentially you should only need to adjust it once anyway. unless its a proper racecar and you need to compensate for fuel and tyre wear over 30laps (which i think andy san you race yours?)
