Title: Front caliper mounting bolts
Post by: Doc on February 10, 2018, 12:00:47 pm
Anti-seize or red loctite?

I put nothing on mine.  They don't need it in the climate I live in and the book did not ask me to put anything on them that I recall.

Hi,
       If you put RED loctite on them... :o

You are going to be hating life... :(

Next time you need to remove them! :-[

I use Moly Paste on mine and tighten good... ;D

No problems! :great:

YMMV! :truce:

The SERVICE MANUAL says to use "non-permanent locking agent".  For most of us that is BLUE Loctite or equivalent.  Note that the stuff Kawasaki uses at the factory is actually red.

Yupp, blue Loctite.
Or tighten good and check frequently.
     (I once found mine loose)...

Ride safe, Ted

Same here. I just make sure the bolts are good-n-tight without pulling threads. If I were to put some lock tight on them it would be Blue.

Anti-seize is the first thing I do to the brake caliper bolts when I get a new concourse 1400. My first concourse 14 had 10,000 miles on it when I bought it and the caliper bolts were seized so bad I rounded off the Allen heads and had to cut a slot with the dremell tool . I actually bent a snap on prybar in the slot. I did finally get out. Good luck

The red stuff from the factory is the equivalent of BLUE Loctite....maybe a tad stronger.

My question is, if you're not replacing the rotors why are you removing them?  :??:

With them heating and cooling, they get tight enough on their own.

New rotors and pads

Thanks guys - it sounds like a little blue loctite will do he trick.  Next question is how much do I reduce the torque setting due to the loctite?

I take off my rotors when I'm getting new rubber mounted, and take them into the dealership.

This keeps both me and the idiots at the Dealership from messing up my rotors.

**Are you supposed to reduce Tq settings when applying Loctite???  :017:

Yes, in most cases torque specs are for "dry" fasteners.  If you apply anti-seize, thread locker, or other lube, then you should reduce the torque by an appropriate value.  In most cases you'll want to reduce the torque by 25%.  Note that if the assembly calls for thread locker, you will not want to reduce the torque since they generally figure the reduction in to begin with.

What page of the service manual are you seeing it mention using thread locker?
Title: Re: Front caliper mounting bolts
Post by: Gscott on February 15, 2018, 10:46:39 am
For me, Blue Loctite and 25 ft. lbs. No problems coming loose or removing to change tires. (so far)

The 09 service manual does not show the need for a non-permanent thread locker for the caliper mounting bolts as stated the tourqe is 25ft lbs. The thread locker is shown for the caliper assembly bolts for this year.

The bolts suck! Heads round out very easy even approaching the correct torque. I wouldn't put anything on them but maybe anti seize. These are the same crappy bolts Suzuki used on the 04-05 GSXRs and we were always having trouble with them on constant tire changes at the racetrack. Most swapped them for a conventional hex head bolt type that was a little harder than the butter metal of the allen head bolts.

Or if you are concerned about them coming loose just safety wire the two together on each caliper. That is how it is done on a racebike  ;D

I was obliviously brain dead & not paying attention on my first post. For some reason I thought read as ROTOR bolts.  :-[ :-[ :-[ :-[  That was the reason for my question.

Anti seize on the caliper bolts for me.

Carry on & don't pay any attention to me.

I've looked twice on my 2015-2016 service manual and i cant find a refrence to putting anything on the threads.

You will regret putting locktite on those bolts. You may strip out the heads next time you remove them.

Ditto here!  I would have sworn that we were talking about the BRAKE ROTOR bolts here.   But the CALIPER BOLTS do not get LocTite applied although I always use anti-seize on them to prevent future problems.  These are steel bolts that thread into Aluminum threads.  A RECIPE for corrosion!

And I'm not convinced anti sieze is appropriate.

Maybe an automotive brake caliper where its subjected to harsh road salt would be appropriate for some anti sieze but i dont believe putting anything on bike caliper mount bolts is a good idea either unless its driven in real harsh conditions.

I put a thin light coating of Marine grade grease on mine. Same with the pinch bolts up front. Same with the other hardware in the back. If fact, just did this again when I put new tires on. I even apply a thin coating of grease on the wheel spacers where they contact the inner sealed bearing surfaces.
