Default Front Disks

Well i had my f2 donated to me by my younger brother, he bought it but then at the same time got a hornet so he gave me the f2,it had 2 brand new tyres on ,when it was delivered to me I have done a a few little jobs and tidying up on it,yesterday I took it out for the first time, i just went local round my estate to try it,i noticed a loud clicking noise coming from the front wheel area, at a junction as i dipped my clutch the bike stopped on its own, at 4.5k revs in third it was only doing about 35,it felt like the front brakes were binding, the disks were not hot,however I really need new disks and pads,im thinking of organic pads,i have looked on ebay at disks but most of them are for 95 model f3, mines a 93 f2,will f3 disks fit on mine, here is photo I took of the disks the pads are down to minimum .

Rotors from an F3 will not fit an F2.
But the good news is, you probably don't need new rotors.
Unless they are really warped or they are well below the minimum thickness, they are should useable.
I've run a couple sets of rotors below minimum thickness and they didn't warp.

You can use a micrometer and dial gauge to check run out and thickness.

Most of the time, new pads and cleaning the caliper pistons and slide will get everything working again.
Honda OEM pads are very good. For street riding I'd go with them.
Yes they are a bit more expensive, but they have a good mix of hot/cold & wet/dry & predictable behavior.
Then extend the pistons a bit, clean around the seals, push them all the way in and make sure they move freely.
Also clean the calipers slides and lightly lube.

Thanks Phil, i will order some pads in the meantime i will clean the calliper pistons and change the brake fluid, i did put the bike on its main stand and got my son to press down on the back while i checked the front wheel, i can here the pads rubbing against the rotors but the wheel moves freely, many thanks for your help.

Sounds like a plan. It's normal to have the pads slightly touching the rotors, so you might hear a little scrapping.
But you should be able to spin the wheel without a lot of drag. Cleaning the calipers will help with this if they are sticking a bit.
