Loosing Brake Fluid

[AlleyCat]

As the heading suggests, i lost all the brake fluid in the resevoir (i found out the hard way when i was driving down my road and went for the brakes.

so i topped it up, left it. drove it to work the next day, everything was fine, brakes all good. hoped back in it after work to go home and everything was gone again, all the fluid.

now i checked the obvious bits, wheel cylinders, brakes hoses etc there aren't any visible leaks underneath the car. its a 1990 studio 2 so has the type 4 master cylinder which was replaced around a year ago.

any suggestions? maybe if missed something blatantly obvious?


any help is appreciated.

hmmm hard one, id say get it over a pit or in a lift and get someone to press hard on the brake, then look around.........

are there no obvious wet paches??

no obvious wet patches, i do have an engine oil leak. but thats a separate issue.

im going to got my mate to have a look at it, hes quite handy with this kind of thing.


thanks for the help
