Hi,

I have just filled up the brake system with fluid this morning - first time since rebuild - and after bleeding I have fluid coming out of the master cylinder cap when I press the brake pedal.

The fluid goes round the brake system fine and the bleeding went as expected, but as soon as all the bleed screws are bolted up and pressure is applied the fluid comes out of the master cylinder cap.

Is it just a problem with the cap, does it need to be air and fluid tight - or does this sound like another problem, maybe with the cylinder?

Thanks
D
