1992 dodege dakota 4x4 problems changing the brake lines I was wondering if I could find a diagram somewhere

The only problem is that there is a little box (or bank) by the driver sie wheel and I can't get the 3 lines that go to it out. They are so rusted they just break right off.

You are going to have to pull that brass BLOCK. With the rusted lines(inside and out) the rust has been forced to the prop(proportioing valve). These can be opened up and cleaned of rust and you will have a better chance of getting the hydraulic fittings out with a small pipe wrench or use a torch SPARINGLY ! you can buy a new prop valve for $50 bucks-just make SURE it's for disc-drum setup(yours?). Otherwise the internal valving will be different. You don't want the rear wheels locking up before the front discs!!-Derfly You are going to have to pull that brass BLOCK.
