This is important because you've said that fluid is unavailable at all four wheels.

You also said that this fault occurred after your mechanic fitted a new brake pipe. Which one?

Simon.--I think fitting of that brake pipe is irrelevant in this case.--If nothing is passing through the master cylinder then there will be no fluid passing through the system at all.

Possibly by just clearing the blockage or by fitting a different ( new ) master cylinder most of the problems will go away.

I think the --Closed Valve---a number have folk have mention is some kind of object blocking the outlet to the master cylinder.

Stripping the original out would provide answers.--- Go, do it now.---
