new master cylinder

just fitted a new master cylinder, as the old was weeping all over the bulk head, i now cannot get the flexi pipe between the resiviour and m/c to seal, the old pipe came off very easily and the new one supplied with the cylinder seems a nice fit, but leaks, ive tried refitting the old pipe but that now also leaks, any advise would be great before i end up with another ltr of dot 4 all over the garage floor.
thanks in advance Steve.
 
That is a pain isn't it Steve. If you have not already, buy another piece of brake fluid specific hose to link the reservoir with the pipe linking the master cylinder. Take your new cylinder and wind the old thread with pipe in and out numerous times. Remove and wipe away any residual material. Repeat and repeat. The mating surfaces should be totally smooth and free of any debris. The seal is made purely between the domed end of the pipe and the corresponding surface within the cylinder. Good luck!

Ron.
