Brake fluid leak

[Till Gnann]

Noticed a very slight drip when the engine was running, so had a look round.

It's very slightly "weeping" from the module/pump area. There is one pipe that's different than all the others, it goes to drivers side wheel, the leak seems to be from that area of the unit on first look. A bit of fluid on the underside tray and then drips out.

Can anyone advise, do you units fail like this or is it, hopefully, just a failed pipe?

Will try to get a better look in the daylight today

Cheers

The angle of the front pipe does't look great, also looks like it has been replaced

Yes, it looks odd compared to all the other pipes. Hopefully I just need to replace that pipe.

Agree, looks like a replacement cobbled up not a standard pipe, would suggest its started to leak due to the bend they put in it which has put some strain on the joint where its screwed in.

If yours is ABS ASC + T equipped this OEM diagram shows shape of pipes

First thing to try is to tighten the union, it could well just be loose. The angle of the pipe has no connection to it leaking, it has just been poorly made. I see many much worse than that which are not leaking.

So, I've loosened and re tightened the nut/union.

Noticed it's a different nut size than the others, but so far no more leaks.

Looks to be a dodgy repair done at some point.

Thanks everyone.
