Hello!
Problem is with hidrostatic brake. It has to brake straight away when you take foot from pedal but it brakes with delay. And also there is problem with starting. It starts to move forward only on last few centimeters of pedal move.
Best regards

Hi Edgar.

I understand you mean 350-03.

By "brakes with delay" you mean hydrostatic brake or braking with the middle pedal (not presumed for application while driving)?

If it's brake pedal - check the brake valve (under the floor near the front axle)
It it's hydrostatic braking - it may be caused by the leakages on servo, or problems with servo electrovalves.

Such conclusions from the first glance.
