Hi. My rear brake started dragging recently, getting stedaily worse. To the point where she wouldnt pull up hill. So I thought probably wants the pads changing out and clean up the pistons to free them up. So this week my new pads arrive and I swap them out. I must say that the GW caliper is probably one of the easier bikes to change pads on IMHO. I noticed, though that when I was trying to push the pistons back in, they would only go so far back until starting to pus the other one out. So I packed the 2nd piston to stop it moving and gave the other on some gent persuasion(!) and it wil not budge past a certain point. This worked on all 4 pistons front and back. So after a bit of searching around this great forum, I guess it must be the return holes in the MC blocked. I then try to remove the MC for examination to find that the flare nuts are rusted solid. I don't have a flare wrench and cant get a vise grip on to it in situ. My questions are, does anyone have any opinions on using an inline connector. I tought maybe I could cut the line and remove it that way. I can then effect a repair with a bit more space to play with. Dont fancy ripping out the fuel tank!. Are the brake line a 3/8"pipe? I think this seems to be the cheapest option to the problem. Any Thoughts?!
