Hi all I am just asking if any one has had anything to do with the early brake valve kits for the 90series that used a take off block on to the external filter housing then fed the oil from the valve back to the block .I have made a block to what I thought like the right spec ( actually unsure of the internal drilling )
The brake valve does work but only if one of the spools is operated at the same time in any direction .
Thanks in advance
