Leaking Brake Line

[jgeorg]

I noticed that the brake fluid reservoir in my E420 has been going down as of late. So I looked under the car to find a wet spot above the exhaust pipe just in front of the rear axle. I'm sure the line needs replacing and I'm considering doing it. Looking at other threads, I hear that the suspension needs to be dropped. With good mechanical skills and basic tools, I wondering if I can reroute the line/lines in question to avoid having to do this given I'm working with a jack and jack stands. I think I might buy the line/lines from the dealer already flared to avoid the tooling. I'm counting on the 11mm nut attaching the line to the hose to be stubborn but hoping . I have a question about the line/lines supplying the rear brakes. Is it 1 line with a T or are there 2 separate lines? My DIY thinking and budget says think about it but some threads are telling me otherwise. I'm also curious what this will cost if I do it versus the stealership. On a difficult scale out of 5, what would this rate?
