Thats a simple fix... Just replace the brake line... Then go to petland and buy some clear aquarium tubing. Have a large amount of brake fluid handy and get a friend to help u out. Now first fill up the resevoir with the fluid. Then place the clear tube on the nipple on the brake caliper. Open the nipple a slight amount (just enough to let the fluid out but not let air seep in) and have ur friend pump the brake pedal....... Take the other end of the tube and dangle it over the resevoir making sure ur resevoir is "ALWAYS" full. As the resevoir starts to drain (because ur friend is pumping on the brake pedal) continue to add fluid so the resevoir doesnt run dry. Always keep it topped off. Eventualy u will see the fluid pass through the clear tube and should end up going into ur resevoir.
As this process progresses, u will see bubbles in the tube but will eventualy clear up and it should look nice and fluent. At this point its a safe bet to close the nipple. Do the same thing to the other caliper(s) as well as the abs unit asuming theres a nipple on it, untill every nipple has been bled and no bubbles pass through the clear tubing. Just to be safe i would redo all the calipers one more time as ur resevoir was completely dry to begin with.
If u do this corectly then ur brake pedal will be the same or better than before ur line busted. Just as aside note, i would replace the other brake line cause if one failed, then the other is not far from it. Good luck
