I haven't used it in a while becuase I find that the bolts are not loosening up at all. That said, all my bolts still have loc-tite on them. What's the best wayto clean them up to apply a fresh coat?

When changing a cracked rotor at the track what do you do? I guess you could cary a spare set or something that are cleaned up.

Most people don't use it anymore because they are taken off so frequently. I stopped over a year ago ... no issues.

Heat is the easiest, wire brush is next.

^ Good call.... just wanted to double check. I will use my vice and some heat to clean them up after this weekend at VIR.

Would it be ok to use a quick blast from a torch and a wire brush? Or is a lighter enough?

I don't use it either but to answer your question, I use a tap in the holes and a die on the bolts with some WD-40. The big bolts that hold on the steel bracket to the upright are M14x2.0 thread size.

^ Do you know what size the caliper slide pin bolts are?

Thread chaser or a thread file.

Wire brush.

The best way.....

Depends what you mean by best, but if its simplicity just replace the bolts with new ones, and keep the used ones for spares. The tap would not be at the bottom of the list if I ranked the above suggestions simply because it cuts and can weaken the threads. I have used all the above methods with success however. My recommendation would be to throw a thread chasing kit in your toolbox. It can repair damaged threads as well as clean them and a good kit is only about $50. I use mine quite often. Good idea to always clean threads, if not replacing bolts, when they have sealer or locktite. Even new bolts sometimes don't have perfect threads. Anytime engine work is done, such as r/r cylinder heads one should always chase the threads in the motor and blow out the holes with compressed air.

That is what I have, but you can get the craftsman one for about half the price and its nearly identical.

Ditto...makes for quick work.

That's what I do now. Used a wire brush until I had to get a tap/die set a while back, but it's a lot more work.

It is an M8x1.25. How do you wire brush fans clean the internal threads? If you don't do that, it is only doing 1/2 the job.

I have used a wire brush and sometimes a utility knife for really stubborn thread locker...
Hdd to slap myself that I never thought of a thread chaser...
