Tonight I was working in the garage, changing the front pads on my 06 TL A/T. I had no problems on the passenger side, but while I was resetting the caliper on the driver side, there began a steady "drip drip drip" of yellow fluid. The flow was landing about a foot towards the center from the wheel, maybe just a hair towards the back end.

I did not open up the MC or bleed valves while doing this - never have had any issues doing it this way on other vehicles, so I was a bit surprised. Anybody have any suggestions as far as where to look? I am hoping it's simply the MC overflowing and will only require a small topping off.

As of right now, I've cleaned up the spill and will check back in the morning to see if dripping continues overnight. Of course before I wrap it up tomorrow, I'll be pumping the brakes a few time to move the caliper into position and also to see if any fluid appears again.

Cheers!

 

reservoir overflowing while pushing pistons back?

 

Certainly an easy way to check, take a look at the MC reservoir. That brake fluid is nasty as it will remove paint.
Always siphon fluid out of the MC before installing new pads, or better yet, undo the bleeder and push in the piston(s). This way you won't be pushing the possible contaminated fluid back into the system.

 

Is this for sure what the issue is or are you taking a wild guess

 

He can't tell you for sure as he isn't doing the work on your car or seen any pix. With that said - it is a very likely scenario and he could be right.

 

thread is from 2011... and that's the exact location of where the fluid is and can overflow....
