Long time lurker, first time poster....

Recently purchased a 2014 LX570 with 164k on the odometer. Vehicle is fantastic condition

Having an issue with the brakes that has me stumped. Under normal braking everything is fine. Under extreme braking the rear left tire locks and the LX starts to skid to the right rather violently and the ABS never activates. There are no ABS, TSC, or error lights that trigger at all when this happens. I've bled the lines, checked the calipers/pads, and everything checks out fine. The master cylinder was replaced by the dealership right after we purchased it due to the brake lights not activating (this makes zero sense to me, but they replaced it with a brand new unit and the brake lights worked...) so I'm about 99% sure my problem is there.

I came across this on an FJ forum while I was researching the issue and it sounds EXACTLY like what I'm experiencing, but I cannot for the life of me find a good picture of the correct line position on an LX or LC to see if these idiots put them in the wrong location on the MC.


This is a picture of mine, and I can see where the stooges at the dealership (this was a private/used car dealer, not a Lexus/Toyota dealer) were grabbing at the line with pliers, which would lead me to believe it wouldn't line up easily so they had to make it fit:

I appreciate any help on this!
 
If someone could post a picture of the brake line routing into the master cylinder in their vehicle that would help rule that out for me.
 
Did you use Techstream to also bleed the booster?
