i have a new master cylinder
new lines and fittings

it seems to be leaking either from or both
the plate that sits between master and booster i see fluid dripping from booster side of that plate

and the bottom bolt of the master cylinder

any ideas any1?????????????
any1 had this before??????????/

its a 120y booster/master cylinder setup

i noticed this when i was under the car and want to fix it but want a few ideas before i pull all appart cause its a pain in the ass

thanks

It's a bad master cylinder. Brand new, but it's leaking. Brake fluid doesn't run through the booster.

so its imposible for a good master cylinder to leak from
the bolt
and that plate between the booster and master

if i explain whats happening to the break place i hope they will replace it for me if thats the case

what a pain in the ass you wouldnt think a new product would be faulty

NOT HAPPY

If you have fluid coming fron the back of the master cylinder, regardless of what it's attached to, then as Ddgonzal said, the chances are that the brake [not break] master cylinder is faulty & that it is leaking fluid past the seal on the rearmost piston.
Damned unusual for a new one to do it. but is can happen.
If it's faulty, then they should replace it under the guarantee.

the plastic reservoir on my ute cylinder was hairline crack ; leaking fluid down fire wall. easy fixed though.

it sure is brand new
i bought it from a local BRAKE place...lol...
how could a seal go on a new master cylinder???
i double checked and it comes out between the master cylinder(bottom) and the plate on booster
not looking forward to pulling out and bleeding all over again

is there any way i could have stuffed it when installing
i cant imagine many ways i could have stuffed it appart from being faulty from factory but i would have thought the chances of that are very low but my luck spose the odds are there

i did notice the reservior clossest to back is lower then the front and when i installed they were the same im pretty sure
i checked the reserviors and cant find any leaks i was hoping it was that or the clamp loose or something but no luck with any leaks around there
