I had to realign the rear brake on the bars. The screw loosened perhaps a turn and felt some resistance. Could not tighten or loosen.
Sprayed a little GT85 and Triple checked that anti clock wise would loosen it gave it a go and.......

What Can I do!?
Can you get at the end with needle-nosed plyers?
Failing that drill it out and get a new thread and larger bolt put in?
Or give it to your LBS...
Have you sworn yet?
You have NO idea!!! yes I’m still swearing!
I tried the pliers but the screw aint budging.
Drill time.....
Try drilling a smaller hole in the remainin bolt and then use an easy out. It has a LH thread so as you screw into the bolt it bites and hopefully undoes the remaining bit of bolt...
Give it a good soak in penetrating oil like plus gas for a day first.
You could try warming it with boiling water too....
Is there enough screw sticking out to cut a groove then use a regular flat bladed screwdriver?
Well that was lucky! Managed to use a normal metal drill bit, on the return the small screw came out. Although I think I may have damaged a bit of the thread.... Will have to buy insanely expensive red bolts now. 🙁
If I were to buy the bolt somewhere else, what size is it? anyone know and where to get it from?
Probably not a good idea to guess but i think they are M4.
Take the other bolt to a nut and bolt supplier.
Send it back to Hope...........oops, sorry.
Expensive bolts... Either stump up if you want another light bolt or take the one from the other lever and measure it up and get a less light, stronger bolt.
FWIW, there's a specific tightening and removing order for these bolts- when fitting the top one must be fitted first and torqued to 3nm, then the bottom one- removing is the reverse of fitting. Weightweenie parts sometimes need a bit more care.
Mate had a few M4 bolts which were steel. Used those.
Bikes all working now. I am a very lucky boy.
