I realize your frustration. Most of us have hit brick walls before and beat our heads against them only to eventually discover the problem was butt-simple and we just overlooked something along the way. It happens.

The brake system consist of a master cylinder a brake line and a slave cylinder. Every hydraulic circuit works the same way using the same principle. You must have a pump (master cylinder) large enough to move "X" amount of fluid within a closed circuit (line) to a slave cylinder (caliper). If there is no air (or blockage) in the system and the master and slave cylinder are working and sized properly....it has to work.

Let us know what the shop discovers.

 

Problem is solved :

Apparently the new forward controls I bought were lying an a shelf for quit some time , the cup that should push the oil out of the cylinder was hardened and had shrunk a bit , pushing oil back instead of in the oillines

I opened the cylinder and did not see anything wrong , glad it was a standard size cup , they replaced it and fixed
