Rear brake bias valve
Hey
I Seem to be having troubles with my pedal getting (spongy'r) every now and then, i have a fiddle with the bias valve and the pedal goes nice, then it gets (spongy'r) again, also seems that the back brakes loose effort, if i tighten the bias valve up it seems to be ok for a while then goes back, theres no leaks and its a brand new master cylinder, System bleeds fine but only when theres weight on the back end. I know they leak for a pastime but mine isnt and doesnt look that old.. can they cause low brake effort on the rear? it's almost right the way in now! lol Dave

the rod will not be getting gripped enough at the valve thus loosening off.
Check the olive is still on the rod. easy fix is cable tie the bias valve shut.
