I worked as a tech in three different dealerships.

Two were mercedes and one chrysler.

In all three places, a technician could get fired if caught not apllying blue threadlock to caliper mounting bolts.

It's just preventative liability insurance in case someones brake bolts fall out while driving.

There is alot of stress on brake and suspension components and nobody wants bolts to walk out on them.

I also think think it develops a more competent technician that pays attention to safety and thorough workmanship.

We also would have to torque theese bolts to the proper specs.

A shop foreman could can you for not doing that as well.

Theese rules keep you, as a tech, on top of your game especially when working on someone elses vehicle.
Nobody can afford to lose a loved one due to an incompetent technician.
