    2000 Eldorodo Brake Line Replacement

    Hello to all my fellow Caddy Owners. Im new to the site and glad to see there are so many members available to help each other with these nice cars. I just purchased a 2000 Eldorodo, The car is in mint shape for the year and having 100k miles on it. Upon buying it from an old coworker he had told me from the beginning it needs a brake line replaced in the front. He had one rust out in the back and got around to replacing it. After getting it changed he went to bleed the system and one of the front lines blew. I got the car up on stands and found fluid underneath the drivers side of the front end. I removed the tire and found the leak is behind the fender well and about impossible to see. They sure do pack the engine and all its components into these chasis! I tried finding a brake line diagram so possibly I can just run new lines leaving the old since I cant see them nor get to them. I haven't spent a lot of time yet on it but got discouraged with what I see already. The most I could find was a quick You Tube Video where the guy had the motor and part of the front end suspension off of the car. It looked as though the lines are tucked in around the motor and along the front frame rail.
    If anyone has any tips or suggestions I would appreciate it. The sooner I get the line fixed the sooner I can be on the road and get to enjoy this car.
    Thank-you

    Re: 2000 Eldorodo Brake Line Replacement

    What is the part labeled #9 ? Any one have an Idea how long a brake line might last around the chicago area . Mine is starting to look pretty bad . Do they have any SS replacements .

    #9 is the proportioning valve. Part descriptions are provided in the included link.

    The proportioning valves are made of aluminum and normally don't need to be replaced, thank God to that because are way more expensive than you would expect.

    What module are you talking about?

    Re: 2000 Eldorodo Brake Line Replacement

    My terminology may be off a bit. On the front drivers side there is a box where all the lines run too. That's exactly where Im seeing the brake fluid dripping from underneath yet I cant see in there to determine a line or the box. I think that is actually a proportioning type valve.
    As for the guy in Chicago. Im from Cleveland and the winter salt has for sure taken its toll on the brake lines throughout the car.

    The "box where all the lines run too on the front drivers side" (#22) is the BPMV (Brake Pressure Modulator Valve). The proportioning valve (#9) is in the rear.

    If I'm reading you correctly you are saying that the bolt heads are no longer octagonal? You may have to try a small pipe wrench if you can get at it with one.

    Re: 2000 Eldorodo Brake Line Replacement

    Yes thats the problem. I know I can get the whole caliper off with the cable still on and do it backwards but it will be ugly , That small pipe wrench thing could work , right now Im pounding on the next sized smaller socket with a hammer but the dam thing wont break loose. Normally I would use heat but I am worried about the capilper getting warped and the piston seizeing . A neighbor mentioned a loc tite product that would freeze the thing loose . but Ive never seen or heard of it

    Re: 2000 Eldorodo Brake Line Replacement

    The caliper is cast iron so I wouldn't worry much about warping, but it may damage the rubber seals. If the bolt corners are gone, pounding on a smaller socket isn't likely to help very much. What ever method you use, before going at it, try giving the bolt head a good hard whack with a hammer. That can break the bond between the bolt and caliper better than increasing torque.

    Forget the center punch. Just use the flat head of the hammer. Brute force wins out over finesse every time.
