Angry 2010 X3 Rear Brake line wear

During normal maintenance I was told by service that both rear brake lines have been worn by rubbing on the axle. New parts have been ordered and the tech has bent the brackets to prevent further wear. To me this sounds astonishing since it appears to be a safety issue which could be due to some design flaw unless it's somehow unique just to my vehicle.
Anyone have advice? I am nervous that the same problem could reoccur and result in a fire or rupture.

How many miles do you have on your 2010?

My 2009 has 102k miles and I haven't seem the issue.

Not impossible to happen but the brake lines are nicely hidden under a metal heat shield/sound barrier. The only rubber part that is easily visible is going to the caliper after routed above axel. I would be curious to understand how they rubbed on axel in the first place. Have them inspect for broken spring pig tails...

Only 36,000 km? (roughly 22,000 miles) Are you under warranty still? This should be fixed for no additional cost to you

Yes, all on warranty. I am just uncomfortable with the safety aspect and how this could happen.

The brackets probably got bent at some point. Most likely during towing at some point. I seem to remember this happening to another model from a tow. I will give it a little more thought.

Bob, the dealer asked me the same thing and the vechicle was chained up on a flatbed tow earlier this year because of a major transmission oil leak. I wonder if this was the problem and I wonder if there are any other potential issues resulting from the tow?

I think you might have found the cause! If you can remember where it was lashed you can ask your dealer to do a good inspection of those areas.

Yep I think you have found the answer. Good thing somebody noticed it before the lines leaked and caused you another tow. You would not have completely lost your brakes but the pedal would have dropped and you would need a change of underwear. If you ever get towed again make sure they use the big screw in tow hook from the trunk and keep track of the cover as they will loose it.
