Hello  everybody.
Just want input from anyone who has repaired brakes on  C303/4.
Is the warning valve useful or not? It was supposed to  be for Swedish  market only. Or is it a gimmick and not that useful. I am thinking of taking it out of brake circuit and replacing it with a 2 circuit block. I find it cumbersome to remember to remove contact assembly every time you bleed brakes. And if you forget to remove the contact assembly,  the nylon pin gets sheared off when you  apply the brakes after a bleed.
Some feedback please. Is it worthwhile keeping or not?
