which brake balance is the best to use,sierra which has to be at 75 degrees or a fiat uno one that is adjustable.

The Sierrra 'G-valve' is not suitable and will not work properly on a Locost.

Which braking components do you have on the front and rear axle? It may be that you don't need a valve.

I have Girling M16 front calipers and MkII Escort 8" drums on the back axle and my car manages very well without a valve.

sierra front and rear discs,and master cylinder

Hi

As u are running rear discs u will need one I used the uno one like most

i am led to believe that a valve as fitted to mondeos and 90's fiestas are as good as anything so have opted for one of these

after sva i will fit an adjustable bias valve for when on track
