Wondering how big of a job this is. My lines (tubes) are looking corroded and rusty.

 

you mean the metal ones running along the underbody? that could be a *****...

 

it's a B-I-T-C-H.
but you should be able to buy the complete lines at the dealer for a reasonable amount and save a LOT of headaches.
DO NOT USE COMPRESSION FITTINGS ON BRAKE LINES.
do not cut and splice your brake lines

 

i got an upper clutch line (master cylinder to junction) for $18 from courtesy. but the long, winding brake lines won't ship as gracefully as my clutch line did. according to courtesy one side is $12 and the other is $23-30 depending if you have ABS or not... that seems kinda low tho...

but yea ALWAYS pay attention to the years and options listed. I got a slave cylinder piston kit, and it turns out to have been for the aug93-up... i think. it didn't fit right, even though it was the 'same thing'.
