Hi all,
Just had a disappointing weekend. Having rebuilt my twin master
cylinder back up with the necessary seals, fitting it along with the
bracket to the car. At this stage there is no motor or gearbox, so I
fitted a union with a short length of pipe, which I folded flat to
the clutch side of the twin master cylinder, this I hoped would allow
me bleed out the brake system, which I plumbed some time ago. I
connected up the pedals, took that unusual plate to allow me access
to the rear of the cylinder off (all side screen people know the one
I'm talking about). Poured in some very expensive silicone brake
fluid gave a few tentative pumps on the pedal, hey presto! fluid
coming from the pipe union at the back of the cylinder. It was
seeping from the hole in the union that the pipe goes through (sorry
can't think of a better way to describe the location), not from the
threads, i.e it was seeping past the pipe. I nipped the union up, but
to no avail. It was also doing the same thing at the other end of the
pipe at the banjo connector, again leaking past the pipe. Anyone any
suggestions where I have gone wrong. I know I flared some of these
pipes myself, while others were bought in the correct lengths with
the unions already on. I used Cunifer, cupro/nickle pipe supplied by
Revington TR. I can't remember I the leaky pipe is one I made up or
not. How crucial is the contact of the flare on the pipe with the
exit point of the fluid in the master cylinder or wherever the pipe
connects ?. Any advice welcome here, I am just hoping this does not
repeat elsewhere on the rest of the rigid pipework, when I eventually
get fluid down to them,.
