I'm in bad need of the master cylinder cap for my folk's 2002 Ford Escape. I just need the cap, preferably one that doesn't leak like their current one does. The old one leaks about 1/2 of the fluid out every month now & I'm afraid I'll forget to re-fill it for them, so I gotta find 'em a new cap. Let me know if you run across one & how much you think it will run. Thanks!
