   Installed all my new brake lines from front to back and all the front lines too, new 2-port MC and bias valve.
   I have unscrewed the bias valve all the way so it has maximum brakes to the back but its still not enough, I need more power to the back?
   Had it on some brake test rollers at mates garage and the readings werent great, werent back but not as good as expected and would only just scrape through an MOT.
   Is there any way of adjusting my bias valve more?
   I have this one....

   No. If it's fully wound out and the brakes are still shit you have another problem. Load compensator still on the beam?

   Wouldn't matter if it was if he has by passed it.
   
   What are you trying to achieve with the rear brakes?
   In the real world they do very little braking anyway

    Wait...
    
    You wanted more rear braking so you fitted a bias valve that can only ever reduce rear braking by design?

    They're not cos before, majority of the braking went to the back and they locked up very easily!
    Also extra 10bhp for being more race car
