VOCA calipar do not fit with VESPA PX150 2011 - Parts dont FIT!

Hello everyone ..


Recently I purchased .. 

Voca- Brake Calipar.


Then the - AF parts for radial brake caliper 


So these parts would work and fit together.

After installing. They don't fit with the wheel hub!!

Back of hub is about 5mm to deep and wont pass the calipar.


Any help or advise with this matter would be a huge help
