The bias brake valve (may be called something different) adjustment is a case of adjusting a spring. When the car is heavierly loaded the spring adjusts the amount of power fed to the rear drums so not to allow the rear brakes to lock up. If you ve lowered your car this will only improve performance of brakes hence they will never load lock up. I have a GSI so the ABS system acounts for the wheels locking up but otherwise the chances of brakes locking up is reduced because the car sits lower.
Your comments are welcome !

If u adjust the valve after lowering then it will be fine.......
Lowering the car and not adjusting it is gonna make the rear brakes more likely to lock up, especially when cornering...

Well people read the haynes manual & it basically tells you what it doea as i wrote above it should nt effect your break system as its designed to reduce the chances of wheels locking up so it should nt cause a problem.

Sorry mattyboy i dont want to argue but your wrong. youve got it arse about tit.
My haynes manual has the following description: - (i hope this dont break copywrite law)
"the idea of the break bias valve is that, when the car's lightly loaded over the rear wheels, the breaking efort to the rear is limited, to prevent the wheels locking up. With the boot full of luggage, the back end sinks down, and the valve lets full breaking preassure through to the rear. When you slam the suspesion, the valve is fooled into thinking that the car is loaded up, and you might find the rear breaks locking up unexpectedly - could be a nasty suprise on a wet roundabout"
Oh yea, and why is this thread in the classified and wanted forum?

also if its a 1.2 16v or less then it dont need adjustin cos the vale is in the brake line, not affected by lowering (also says that in max/hayes)
