Got a PBR replacement 180b master cylinder, which is running into the 180B Brake NP Valve. As shown.

I want to run disc brakes all round and have been informed that I need to replace this NP Valve with one suited to disc brakes all round. However is it possible to remove the valve from this unit which holds the pressure in the rear line for the original drum brakes?

This would be an easier option that making new lines and fitting the new unit in the confined space of the engine bay.

Cheers
