Rear bias valves

So if I'm upgrading from drums to discs on the back, and already have inline pressure reducing valves on the 2 outlets on the master-cylinder in the current configuration, would it be worth fitting a load-sensing bias valve too, to compensate for the extra effect of the discs?

If not a load sensing one, then are there any ajustable ones that are dual circuit?

 

you'll need a rear bias valve.... having the rears lock is never fun

 

.. and if you say they're on the 2 outlets o the MC, then they'll be affecting the front aswell, not just rear. aren't they just T-pieces the where lines join?

 

Nah, M/c is 4 outlet 2 front, 2 rear. Just wondering if I'll need any extra biasing as the rear discs would be more effective...
