I have just recently lowered the hybrid and I have noticed that the rears lock up before the fronts so want to adjust the bias valve.
Is it essential to do this for the MOT or will it still pass the MOT even if the rears are locking up before the fronts?
In order to adjust them will it be pretty self explanatory when I look at the bias valve itself? Is it just a case of adjusting it by trial and error till I get the balance right?
Cheers.
