   Take the passenger back wheel off mate and just under the arch you will see the brake linkage valve. I had the exact same on my mot fail and i sorted it myself no problem.
   
   Soak all around the valve with wd40 and let soak and i used pliers and just worked the metal plate and eventually it loosened or try get a hammer and give it a few hits should hopefully start moving it only needs to move up and down a few cm's and thats it
   
   Hope that helps. Just message me if you need any more help

   The bolt doesnt move mate. See the part where the arrow points to ? The part the 3 bolt goes through? You move that up & down its a little flat metal peice that sticks out and that moves and you just work that until it comes loose and thats you

   there is no need to remove it. i had the same prob awhile back. and as explained, just soak with wd40, leave for a bit and use some mole grips and wiggle back and fourth. this will work it loose enough so it will start working again.

    Soak it up and get it moving. I dont know why Peugeot/Citroen didnt cover these in some sort of box to stop them corroding.
