This is a fairly common problem. In brief, there is a pressure relief port in the master cylinder that gets plugged. pressure builds up in the brake lines, and can happen in both front and rear brake systems. Fix is to remove the fluid, remove the resevoir, and clean the hole with a piece of small, fine wire. See this tech tip, complete with photos:

That sounds like a plugged fluid return hole in the master cylinder. Also known as the "spooge hole". Check out the following tech tip:

Breaks Not Releasing?

Wow, that's quite a find!

Good luck with the brakes and keep us posted!

faulty brakes

just let you know how i got on,done what you all said and cleaned out the hole in the master cylinder,pu it all back to gether and bled them ,a bit spongy but they will do.took the callipers of to find out that the disk has been rubing against the mounting brackit for the caliper (not good i hear you say) so i undo the two nuts on the bottom of the fork that holds the spindle,this has allowed the disk to centralise it self in the caliper,(sorted i hear you say)tighten the nuts up on the bottom of the fork and guess what ,it snapped,will keep you informed on what happens next.
