      Safety Inspection Reminder!

      I put my car in the air to do some maintenance and while I had the wheels off, I decided to go around and check over fasteners, joints, etc. Wouldn't you know I found one of my two C6 caliper abutment bolts had backed out almost completely. This could have been a braking disaster!

      It's clear from the dry threads I never put Loctite on this bolt and therefore probably also did not torque it to 125ft-lb like I was supposed to. If memory serves, I did use Loctite and a torque wrench when I installed the brakes, but I must have missed this bolt. Needless to say I'll go back over all the bolts now and make sure they are torqued down.

      I use torque stripes on every bolt I touch. Its a good way to keep track of what you have torqued to spec....it also allows you to very quickly check that nothing has backed off.

      That's a great idea. Where do you like to get it? Do local places carry it?

      Of what type? Split washers have been shown to be inferior to plain bolt or nut through Junker vibration testing.

      How about a Nord Lock washer?

      Those are really cool. They look to do well in the Junker vibration test:





      I've already gone back, added blue threadlocker, and torqued these properly to 125ft-lb. I think that should do the trick without a locking mechanism. These bolts didn't loosen up on their own; they were never tightened properly to begin with. The threads were dry and I found with a torque wrench they were all four (two per side) well below 50ft-lb, indicating I just hand tightened them and forgot to go back to torque. I am going to order the Dykem Cross Check and start using it to remind/reinforce proper tightening. That will also make inspection easier since I'll be able to see if they've turned from their torqued position.

      Thanks for the great replies and help. I have had two recent experiences where I failed to torque fasteners and I am trying to learn my lesson. It's ironic because I think of myself as a religious user of the torque wrench. I own several and I use them even for the smallest of jobs, yet I've managed to miss it for some of the most critical components. At least the maintenance check caught it before I was on the side of the road or in the morgue.
