I am in the process of swapping my leaky master cylinder with only 2 holes for a sierra one with 3 holes.

if i were to fit a brake bias knob (Adjustable) where would it be fitted in terms of where in the brake line?

do you need to plumb the system differently when one is fitted, i guess that all the braking force front and rear is put through this device then it exits to the front and the rear and allows control over the braking forces applied either front or rear,

Hope i explained my question well enough!

Have a look on Austens(MK9R) build site.
Hes got it all detailed in there.

cheers Gordon,

From MK9rs lsite i assume it only governs the amout of pressure to the rear brakes and has nowt to do with the front at all?

Yes, it has nothing to do with the front at all.

Be a little wary about adjustable brake bias valves and SVA. It must pass at both extremes of settings.

I'm going to lock it up for the sva.
