Has anyone tried to top up the brake reservoir. I did and good luck with that!
The designer chappie has recessed the fill point so that it is pretty well impossible to pour from a full bottle of DOT4 without spilling some - I hope that there is nothing below that's important.
Once you have got the DOT4 into the filler things go well until the filler airlocks and goodnight to filling up to the line - not good.
The designer chappie must try harder next time!
