Hello, im trying to repair a leaky brake line in my 1989 Cadillac Deville. I know its in a line running to the rear breaks but I can't tell which line it is that comes out of the master cylinder. It's hard to get at any of the lines, but I can see that there are a couple different distribution blocks. I was just wondering if you could tell me which line running out of the master cylinder runs directly to the rear breaks. Either that or where the line runs and which distribution block goes directly to the rear. Also, if you had any diagram or layout that would be greatly appreciated.
Year : 1989
Make : Cadillac
Model : Sedan De Ville
Engine : 4.5L V8
I've looked over all the lines trying to see which goes where. All I know is that it is leaking fluid behind the drivers side door. I haven't removed any lines yet.
Hello & Welcome to JA,
Clean the area with spray brake clean & have someone sit inside the vehicle applying the brake with engine running for max pressure.look closely at the lines & determine which one is leaking.Remove the one line that is leaking & measure it because the line you purchase will be straight.You will need a new line for the approx length with the correct fittings so that you can bend it & reinstall.It cannot have any kinks in it.
Ok the major problem that I am having is that I can't get at the lines. They run under the engine and the distribution blocks are almost impossible to get to. I even put the car up on blocks and tried to get at it from under it but that didn't help much. Would you happen to know where the distribution blocks should be located generally and if so from which side of the car is it easiest to get at? I understand each car is different but if I disconnect it from the master cylinder I still have to disconnect the other end and I can't find a good way to do that.
I know they are hard to get at why do you think they pay us the big bucks for replacing these parts.I suggest if you do not feel that you can do this job ,have a professional handle it.You are messing with the BRAKES.
