I've fitted one of these http://www.compbrake.co.uk/Brakes/Brake-valves/BIAS-VALVE-knob-WITHOUT-UNIONS/prod_969.html
to the ka, and the system bled out fine to the valve , but nothing would pass through it? Have I the input and outlet pipes mixed up , or does that matter? The front is all bled out fine. :confused:

There are a bit weird when you wind it all the way open they close again. I had to take mine off to figure it out.. But then I set it to the middle and worked from there you have to be careful with them!

there was nothing tho coming through , either wound down or wound out?

hmm... I swirtched the input pipe to tjhe other side.. and now it flows . But when I tightenm (clockwise) in the direction of "More Pressure" , it reduces the flow . Guess more pressure , means more mto the front?

Tristan - My brother and I fitted one of those to a 309 a few years ago, at least I think it was a compbrake one. Never seemed to work right. From memory difficult to adjust flow and seemed to stick as well. In the end we changed it out for a Wilwood valve which was much more reliable, unfortunately though more than twice the price at the time. Philip

thanks for the input . it seems to be working now , but if it does give trouble I'll dig deep and get an AP or similar .
