Peugeot trekker rear brae disc---help

I'm new here, and I need help, I have a trekker 50cc 2007 and I want to change the reat brake to the disk brake, I was thinking about putting a rear wheel of speed fight 2 and a barks pump and everything that comes with it. Is there anyone here who has done this before? Or can help? Thank you

 

Does the trekker motor have the caliper lugs on the side casing, if not i doubt very much you will be able to mod a drum to a disc

 

Yes, there are lugs for the Caliper, I thought to dismantle the existing pads, remove them completely and instead put together a wheel with a disk of speed fight 2
Do you think it will work?

 

really not sure david to be honest , usually the shoes are held on with pins one is usually removable but the other is fixed. it may become more of a headache trying to retro fit a speedy rear rim to the shoed trekker casing .

 

Finally I succeeded
