C4racing

On my '89 coupe there appears to be a pack of brake lines (5?) running along the driver's side lower edge of the car. Near the front jacking point (where the factory arrows are to place the jack) I just noticed that some of the lines seem crushed, probably from a floor jack.

One seems worse than the others, and a couple seem only partially ovalized. Yikes! :eek: I haven't noticed a loss of brake performance but I also don't know how long ago this happened.....maybe years ago. If it's been this way for a long time then I suppose I don't have anything to worry about because the brakes seem to work fine, but now that I've seen the damage I can't stop worrying about it. :sad:

I'd like to know if anyone has replaced the hard brake lines on their C4 and what they learned in doing it. Piece of cake, or PITA?
Thanks. :seeya
