This is my problem. My mk4 estate (non-turbo, it's got a Fiesta RS1800 zetec in it) has just had some braided brake lines fitted.

Now, after numerous bleeds, DIY and professionally, the brakes only bite properly at the bottom of the travel and knowone has found why.

There's definatly no leaks as it's not loosing fluid, a different master cylinder has been tried and the vacuum pipe isn't blocked.

The servo seems to have a lot of brake fluid in it so this seems to be the only thing it can be?

Is it possible that I burst a seal in the servo when I first bled the brakes myself? I have a 2.0L mondeo at my disposal if I can use that? With my existing master cylinder?

Other than that, any ideas? Thaaaanks people
