Ok I rebuilt the brakes on the A1 and installed a new Gov. issue NOS master Cyl.
Purchased here.
Problem is the brakes are slow to release and drag for a bit before returning to normal.
Now when I benched bled the master I noticed the piston was or seemed stuck.
Once it moved in it didn't want to return. I worked it a little and seemed to get better, so I installed it.
In hindsight I should have taken apart and checked.
The Master looked Great and what appeared to be fluid residue I assumed for protection.
So was that some kind of protection that should have been cleaned out?
TM's didn't mention it from what I could find, and no paper in the box warning of it,
like I have seen with other parts in the past.
Did I just get a one of a kind unit or has this been a problem for others?
Now I notice I can release air from the air-pack at the rear trailer valve, but after reading about,
The air-pack and understanding how it works I'm sure this relates to the MC holding pressure on the air valve not letting it exhaust.
