I do not know where your Bremach comes from. I t seems to me that the Springs are the problem.
on the spring in the front ( right side) i see 3 blades an on the other side (Left side) but i can only see 2 blades. Are the blades clamped together? as there is much room between the blades.
They are flat , they should be Hollow ( see picture) , do you have the 2 shackles on both ends ?
