the bias valve is on the drivers side on the beam and is operated by a spring
when the car is loaded up it adds tension so more braking power to the back,
thus when lowered the valve thinks the car is loaded when it isnt, hence why the rear's lock up

you adjust it by losening the adjuster bar off when the car is flat level and not jacked up, set of grage ramps are helpfull"

then while the spring is under a tiny bit of tensoin "no slack" tighten it up and your done

if the valve is fooked or shit remove it and fit a set of brake lines and pressure valves from a 1.2 8v "these have independant pressure vlaves 1 on each side

for once im glad i have a 1.2 8v when i had the 1.4 it had the bias valve and it was shite
