I would like to know if there's a safety recall for 02 ML55 regarding the following issue:

One of the two steel brake fluid lines coming out of the master cylinder has been rubbing with the fuel line. That is how the fuel line has been since the day it was purchased. ML has about 75K miles now. Yesterday, I noticed that the brakes werent working. Pedal going to the floor. I openened the hood and was shocked to see that the constant rubbinng of the steel braded fuel pipe with the brake fluid line made a hole in the brake fluid line causing brake fluid to leak and drop on the engine causing smoke and burning.
The fuel line is also half way towards leaking due to the constant rub.
To me this is just unacceptable and a major safety hazard.

Given that the ML is out of warranty, is this something mercedes should recognize as a safety issue and fix the brake line and fuel pipe for free ? Is there a prior safety recall for this ?
thnx.

I did a quick search for DTB's, Recall Campaigns, and Service Campaigns regarding brake lines and fuel lines. I didn't find anything, and I'm not personally aware of any issues related to your situation. If your ML was in my shop, the first thing I would do, would be to research the repair history. Maybe the lines were inadvertantly disturbed during a previous repair? I'd also find another ML to compare with yours. Sometimes this can be helpful when trying to figure out what may have caused the problem. Either way, I doubt it came from the factory that way. Do some digging and I think you'll find out what happened. Keep us posted.

frankly, I'd like to have some kind of separator between the fuel line and the brake lines. There's about a quarter inch of clearance there, but with the fuel hose being somewhat flexible, and considering what these lines are carrying, there really should be some kind of bumper there. BTW, also take a look at the line from the coolant reservoir towards the radiator. It mat be rubbong on a metal fitting of anothe hose at the radiator end.
