Hi this one’s drivng me fecking mad !! Problem is with the flexible brake lines between master cylinder and reservoir . I’ve had to change the hoses 3
times now .It seems ok for about 6 weeks and does not leak then you look it one day and you find the cotton braid soaked in brake fluid and acting
like a wick soaking it up to the reservoir. I’ve tried braided hose from both Burton and Merlin and both do the same thing and it is supposed to be
suitable for brake fluid (DOT 5.1 I’m using). Anyone else had any similar issues??? The car is still being built so it’s not as though I’m using the
brakes it’s just standing in the garage! Any suggs gratefully accepted

The bottom end looks solid - brake fluid wicks very well, though - any chance it's got a slight leak at the reservoir end & is wicking down the outside of the line? If the reservoir is plastic, it won't take much of a flaw in the outlet to let fluid leak slowly around the joint, and it could wick down to the bottom before building up enough fluid to show...
Probably not the correct type of hose?? You need one with the correct markings on it to get through SVA . Do a search, this has been covered loads of times. Also Jubilee clips are not the best clips to use on small brake and fuel pipes , your better off using proper fuel pipe clips
Brake hose markings:
SYTEC FH013 NBR DIN 73379 B
Think this is ok for brake fluid???
Will check reservoir end
Its probably fuel hose which is not suitable for brake fluid. The fact that it is ok for a few weeks and then leaks again is fairly convincing proof - fuel hose will 'sweat' after a while, actually oozing through the surface of the hose.
you can get the stuff you need from lots of places. i think burton now do it. If you're stuck old land rovers use them.
