car fixing

So I still have this 1992 VW GTI in Pasadena, currently inoperative and collecting dropped citrus fruit in the driveway. I maintain some illusions about fixing it, though I have to admit that the Click & Clack "1-800-Take My Car Please" ads are sounding more and more appealing.

The showstopper right now is the brakes. The brake pedal goes to the floor—I'm pretty sure the master cylinder is busted. But for the life of me I can't get some of the brake lines unbolted from the master cylinder. They are rusted together. Then again, I haven't tried anything more exotic than penetrating oil and a flare nut wrench.

One website says:

Q: How do you remove rusted brake line connectors from master and wheel cylinders?

A: Sometimes it is impossible to remove them even with vise grip pliers. You may have to cut them off and replace the whole brake system lines and all.

great.
