i seem to be leaking brake fluid from the end of the hose where the little sqaure with the bolt is the one that goes to the caliper in the rear...i tried tightening it real tight but it stil seems to be leaking what could it be?

I don't know if they still use it but the hoses used to come with a copper washer that goes under the head of the banjo bolt. The new hose will come with a new washer. Your's might have got brittle. Copper needs to be annealed once in a while. Over time it hardens up.

Good luck,

Steve

are they expensive? can i get it at any auto part store?

and you may need to replace the banjo bolt too. That's not a normal bolt that you were wrenching on. It shouldn't have gorilla-type torque on it. I don't know the spec off the top of my head, but I'm sure someone here can tell ya. Those bolts are hollow and you're lucky you didn't break it by cranking on it.

EDIT: It will probably be similar to step 29 in this document....

Replace the copper washer under the banjo bolt and it will be fine. You try and tighten it also, they leak sometimes. I believe you can get the copper washer at an autoparts store, I picked mine up at Ford.
