morning folks, hope this is the correct section, if not mods feel free to move it.

is anyone on here running a big brake kit (front), 25mm brake M/C & clio servo?

i fitted both a 25mm M/C & clio servo (with uprated pads & discs on the rear) earlier in the year (not driven the car yet) & replaced all the fleix lines with braided steel lines & the hard lines wit kunifer & i was wondering if i would need a brake bias valve?

reason being i have read quite a few posts online about folk running a BBK, 25mm M/C & smaller (clio/mk1 golf) servo & on a few of the posts they have mentioned the above set up causes the rear brakes to lock up pretty quick.

most of the posts suggest that using a bias valve (screw or lever type) will help to alleviate this.

so, does anyone on here with a similar set up use one? bare in mind this is a "fast" road car.

i've got a screw type bias valve already.

so, any experience? thoughts??
if it's got t*ts or wheels it's bound to be trouble...............prove me wrong.
