So i just got my Wilwood brake kit. Looking through the instructions it says to safety wire the bolts that screw into the rotor.

I was just wondering who actually did this? Why not just loctite it or just leave it?

Just keeps the bolts in place in case they ever work lose.

I've never used this technique on a car, but I've always used it on motorcycle sprockets, and bicycle cranks.

Mine are safety wired. I don't know any loctite that'll hold up to a glowing hot rotor. I've see hot bolts work themselves loose, I wouldn't be surprised to see one do it on a rotor in a high temp environment.

Edit, I didn't safety wire mine, they came that way Looks like a giant pain in the ***.

I've had one rotor bolt back out.

Since that time, I loctite red those bolts.

We loctite them only here at Brembo....for NASCAR, ALMS, and the like. You should be fine for a street/strip application on a honda. Of course, a two piece setup will require more maintenance and should be regularly inspected when checking seals and the like on the rest of the setup. I assume this is a 'race/track' type setup.

NASCAR rotor temperatures range from 1000-1200 deg F regularly, if that helps.

I safty wired all the rotor bolts, and the 2 bolts that hold the bracket in place on the hub. Takes all of 5minutes really.

loctite for me, though safety wire is really the way to go

Regular permanent Loctite 262 (red): Good to 150 C, disassemble by heating to 250 C

High Temperature Permanent Loctite 272 (red-orange): Good to 200 C (almost 400 F) according to data sheet, disassemble by heating to 250 C

Thus Loctite has no strength if joint is heated to 250 C, or 480 F as that is the dis-assembly procedure. Safety wire will work at higher temps than Loctite. It just depends how hot your parts get.

I prefer to get my stuff redhot, if the wilwood caliper doesnt explode from heat your not trying hard enough.

As was said ^, Locktite isn't any help when things get hot. It really isn't that hard to safety wire them. Hell, if you want to be real lazy, just run one wire through all the screw heads -- anything is better than nothing.

FWIW, I ran a trackday at Streets of Willow a couple weeks ago. Recently I was working on the brakes, and was shocked how loose the caliper mounting bolts were. Not just one, but both on both sides of the car

I'll be safety wiring the bolts when they're reinstalled...

Dont forget these, makes everything so pretty
