You're really sure there are no leaks?

Last time I was testing a friends car for leaks I parked the car on a clean slab of cement and pumped the brakes, found that the front left caliper bleed nipple wasn't wound down tight enough and was letting fluid seep out. I want back and bled the whole system and replaced the pads because they were down to the metal :shock: and now my friends eyeballs get stuck to the windscreen when he applies the brakes.
