defo your brake bias valve mate .. when you lower the car you are meant to adjust this, look in haynes i think its in there,
best get this done asap before ya kill yaself, braking on the rear more than the front can make the back step out well easy matey...also shite for performance, many of the trackday lot (like me) adjust it to alsmost front only, as do many race cars

yeah seems like mines back only as iv had the backend out asif im doing a handbreak plus when i lock up in a straight line the backend will slide out and its easily contorlled with the front because they still have traction same again like doing a handbreak lol i will have a look thanks mate. just one question though how do i know where to adjust it to?

hey just had a look in the haynes and it only has a guide on removal and refiting of the rear break regulating valve cand see anything about adjusting?

Right mate this is how i did it on mine.

1. There are 2 springs attached to a lever on the back of the bias valve, 1 spring is attached to the lower arm. Now this spring is what adjusts the bias because if the car's lower then it thinks theres weight in the car and applies more rear brake.

2. My springs were seized solid so i was forced to disconect BOTH springs and adjust the bias valve manually.

3. The lever will be seized but persist with the WD40 and you will suceed.

4. When its freed up move it all the way back until it is about 7mm from the rear brake line (youll see what i mean when you do it).

5. Now hunt down some new springs, but for now your car wont try and kill you.

Trial and Error with this 1, dont go braking too hard the first time, just incase there is a severe problem with you front brakes.

Hope it helps
