left hand rear locking up on heavy braking..

[broken willy]

how do you set the rear load sensing valve? im aware its ajustable but which way do i need to ajust it and how much?

THINK you need to unscrew the nut, if its not rusted up.

Just have a look at it and work it back in your head which way it moves when the arse end of the car is lower
