Hi,

I think I've heard of a tool that you screw in place of the master cylinder cap to check if the braking system holds the pressure and detect any leak.

Has anybody used such a tool and could point me to a place where I can buy one?

The only system I've heard of that pressurises the brake system is to help bleeding the brakes, not for testing them.

Though when I've replaced an entire braking system I find it quite handy, after I've finished bleeding it, to keep it pressurised with the Eezibleed (or failing that, get an assistant to press the pedal and hold it down) while I go round with a lamp and check if any of the fittings are weeping.

Good idea for finding leaks, but the braking system is dynamic and I doubt it would detect a worn master or slave cylinder as they move in operation, and can draw in air when going back to the rest position.
