am thinink of removing it altogether and putting in either low spec corsa pressure dependant type in
or
manual adjustment motorsport ones

coz my weight dependant vale seems fucked i feel this coz whenever i have braked hard ive ended either sideways or the rears have locked

i had 3 different grages look and ajust clean my rear brakes and its still shafted

mines always done it
unlowered lowered makes no difference
so i thinkim gonna take the set up of a lower model the pressure dependent type or a 1.2 and just use new valves i doubt they would be as much as my current valve £143.00 without fitting !

you will also need to get brake lines made up also, and you cant buy these from vaux, they have to be specially made.

yes definately cos you will need to limit the rear brakes from what they are or else it will be worse than it is now.
