Ok ill have a go tomorrow when its on the ramps cheers :)

no, you want it loose. you won't lock just the front. and if you do, it's better than the back locking

Ok if i slacken it off to much will it just mean my fronts will lock up :|

It's attatched to a spring that hangs off of the o/s of the rear beam. You slacken it off until the spring is loose. If the spring is tight, then it means you braks will be biased more to the rear and vice versa.

Hi guys, car feels a bit poo under brakeing and under hard brakeing the back steps out now and again, car is lowered quite a bit and ive heard the brake bias valve needs adjusting ... any ideas on how this is done or where its located cheers Rob pics would be helpful..
