aprilia sr rear brake cable setup

hiya all. on my sr i cannot connect the rear brake up. the arm is there and on the end of the cable theres something with a thread in it. what do i need to connect this to the rear brake bar. i have the little bar that goes through today

is it a bit of thread with a nut to adjust.

does any sr geeks or typhoon people have one for me. or know where i can buy one

is this all i need riding a 172 with just a front brake isnt a good idea

many thanks

 

i may have one of these as i got disk brake on my typh now... ill have a look tomorrow im pretty sure i havent chucked it

 

these should help excuse the rust

 

im sure i have that bit with the nut on the end. its bolted to the cable my garage says there something else missing. will dig around tomorrow and see what i need

many thanks guys

 

i already had the bits didnt realise the nut was still on the cable

many thanks all all done
