On my 1992 cadillac deville the right rear brake line keeps leaking that connects into the wheel cylinder I have tried tighting it as tight as I can get it and it still leaks out. Any suggestions. Thanks.

Yeap thats what I am going to do I just have to find someone to bend it. I called the dealer they dont have the steel brake line but they said they could get it but it would be expensive for me because they have to buy 25 foot. Napa sells it and the dealer said they have a hydraulic bender to bend it. I would have to flare it though. DO I have to do a double flare. Thanks.

Went to napa yesterday bought 2 brake lines all I had to do was bend it. The only problem was it was an inch longer but I got it to work. My dad bent it on the granit counter top it did not kink at all it worked perfectly.

Tried the new lines still leaks out the brake line hole on both sides. I replaced the brake line on both sides. Does this mean the wheel cylinder is bad. Thanks.

The brake line was already flared when I bought it from napa. But when I open the bleeder screw on the wheel cylinder it leaks out through the brake line and the brake line is as tight as I can get it. When I close it and pump the brakes it doesnt leak out the brake lines.
