‘14 LX570 rear AHC LEAK (2 Viewers)

[4joggin]

Noticed some oil drops from my wife’s LX. Was able to get under it today and it seems like there is a brake fluid leak. Drivers side rear, right behind the muffler is the location. Not sure if it’s the fitting or the soft lines. I’m assuming softs lines



Need help with getting some part numbers.

Couple pics

Are you sure that it brake fluid and not AHC fluid? Tough to tell the exact location of the leak from those photos.

Yes brake lines. Followed them to the brake calipers

Might be part of the abs system

Maybe AC lines?

please verify with your parts guy first...

kind of strange for that to fail. Have you ever had calipers or lines replaced? Any rust on the vehicle?

Double check that it isn’t the rear A/C lines leaking. It’s not rare to have the paired aluminum A/C lines going into the rear evaporator right there corrode and leak. That’s much more likely than the brake lines.

You need to verify brake and AHC fluid levels.

Just to report back. It was the fitting in the 3rd picture. AHC fitting somehow backed itself off ( no clue how). Fitting is tight, cycled the height adjustment a few times and it seems to be dry still.

Thanks Steve.

You might want to edit the thread title to help others searching for leak threads.

Check your AHC reservoir and monitor it. I'd recommend a full bleed too.
