iam changing the rear wheel cylinders in my girlfriends 2000 accent. i got everything loose except for the brake line. I couldn't get that one to move. I noticed on the new part that the part where the brake line hooks into is different. it has sort of a male end and it looks like the brake line has to overlap it. the original looks like the brake line goes into a hole in this part that sticks out the back of the wheel cylinder. did the part store give me the wrong part or is there something i don't know? hopefully this makes sense so i can finish the job.
