    HELP - braking system re-assembly

    Hi,
    I have empty the engine bay to respray it last winter, and took pictures of full steps...

    BUT, I cannot figure out how to to re-assemble all the parts around the brake master cylinder : brake support, brake fluid reservoir and its support, brakes lines, brake distributor... i have different pieces but nothing goes where I beleived it should go... also because the support was rusty and during the disassembly I have bended/twisted it so badly that the shape is no more correct at all... and so are the brakes lines...

    If anyone here was kind enough to make few pictures (different angles, front, back, left, right...), large and close-up, it would be so nice !!
    Thanks a lot in advance.

    Here is a view of what I'm struggling with :

    gladie,

    The only picture I have handy is from back when I sprayed my engine bay.

    It should give you a little info but I have the fuel lines and clutch slave draped over the master/reservoir. I can get you some fresh and much better pictures tomorrow morning if there are no other responses in the meantime.

    Thanks a lot your you reply and picture.
    Unfortunately I can barely see, I'm sorry...
    If you had the chance to take closer/very close pictures around master cylinder and reservoir, because this is main part where I cannot figure out where goes what, and in which order...
    Many thanks in advance

    gladie - looks like Cas took some great pictures for you and I hope you get everything sorted. Look forward to seeing the final product.

    Thanks a lot your you replies and pictures.
    So nice you did the effort to post pictures :-)
    It is helpfull at some point, but unfortunately we may have different version/year model.
    Mine is 1978 and it is quite very different than yours (didn't expect so much difference in model year...).
    Anyway thanks, it helped for one part of my questions, but the reservoir si not held the same way and if physically different. Mine is held supposely by one small metal branch and stay in the air above the master cylinder but cannot figure out how as I have no room to install it this way... hence my questions...
    Have a good week !

    Hi,
    I think I just found on the Net one picture that might be sufficient to answer my remaining questions, so please don't bother posting any additional pictures...

    Thanks again to all of you
