Do i need a brake bias valve?

[RobMatthews]

Hey guys hoping to fit my kad 6 pot front brakes this weekend,along with a bigger master cylinder(the 929 1" jobby) and have already got the bigger rz rears on the as well,abs has also been deleted in the past,my question is will i need to fit a brake bias valve to compensate for the bigger front brakes?
If so how much should i look at spending on one and where would be the best place to get it?

Thanks for your help:cheers

edit: the car is an fd.

Especially if your going to use the car on track then yes adjustable bias braking will defiantly make your system work better,

Personaly I feel that six pots on the front will be too much to give you a ballenced system on the road, indeed with insuficient braking on the back the system may actualy be worse than the stock system with a good pad and disc upgrade,

"If" you are really serious then the next stage would be to fit your old FD callipers on the back, bias box and if you still want the car MOT\'able a spot calliper for the hand brake.

Hope this helps

Sorry just read this again,

You will really need a bias box to make this system work because with a "strangle" it valve the only way you will increase your rear braking is to put it in the front brake line from your master and restrict fluid to the front,

The only way this valve may work is to put the FD calipers on the rear then strangle the fluid going to the back to give you the correct brake bias
