Ok so ive just put the disc back on etc and on the top of the caliper there is fluid leaking out the blead valve, the thread on it is nakered and it will not stop leaking. ive got a new set of rear calipers sitting in the garage so ive taking the bleed valve out of that a put it in its place. only thing is the tiny little hole at the end (where it screws in) is smaller does this matter???

help
