05 2.0 no brakes... At all.

[Alex b]

So I changed the front discs & pads about 2-3 months ago. The low brake fluid light came on about 3 weeks after so topped it up. Warning lights came on again and was topped up. Did this 3-4 times no idea where it was going. I've pressure washed everything and can't see any leaks. Any idea where it's going and how to fix it? I've also bled the brakes using a gunnison bottle and under pressure I still couldn't see any leaks.

Any help would be much appreciated!

Into the engine via the servo / vacuum system perhaps.

Thanks Geoff, what do you think is the easiest way to find this out? The engine seems fine. Will it effect it?

[geoff]

Bearing in mind I am more used to very old vehicles and not the new fangled stuff I would suggest removing the vacuum line and looking inside for oily residues.
Presumably your vehicle is a diesel and if so hydraulic oil won't hurt it at all.

Check your rear cylinders and the brake proportioning valve, I don't see how it can get into the engine via the vacuum pump.

The base seal of the master cylinder can let go, this releases fluid into the chamber of the vacuum servo.
