Wow man. That's not good. Thanks for the detailed evidence.I did. I did a complete tear-down and rebuild of the front brakes on my 2015 RX350 a year ago. I replaced the seals/boots on the calipers, completely cleaned the caliper pin sockets (like I always do) and tried to perfectly grease and put things back together like it came from the factory. Except I used that garbage from Permatex.
A year and 30k miles later, the pins on the calipers were LOCKED UP SOLID and I do not live/drive in the rust / salt belt. I had to spend 30+ minutes twisting the pins with a wrench and pliers pulling on them to get them out. What was on them? Hardened, gunky purple remnants of the Permatex garbage.
I replaced the rotors, which were purple on the inside surface. I re-used the pads, but they are more than 50% worn.
These 30k miles were 90% highway miles too....
Sounds best not to use it.
