to make along story short - the BP guy couldn't do anything about my car. said it's probably the master cylinder that was just replaced a few days ago; or it could be a valve; or a crimped brake line. they can't find out without taking it all apart. they don't want to do that; and i don't want them to do that. they were able to drive it into and out of the service station without any problems. they bled the brake lines some, but he said there is no way that could be the problem. i asked if there's anything i can do if the problem arises again, which we both agreed would happen. said i could try breaking off one of the brake lines from the master cylinder, but then i'd be running on no brakes instead of all brakes. shit. on top of it all, he charged me for doing nothing. $10. sure it's not much, but it's just enough to piss me off.
