Front rotor bolts

[DucHead]

The front brake rotor bolts require the "security star bits" for removal.  I've now broken two bits using an impact wrench and one by a regular ratchet.      Any ideas on how to get those make the beast with two backsers off?

Usually you need to use a hammer driver...

and perhaps a heat gun.

Heat to cook off the loctite...

Is a hammer driver better than an impact wrench for this job?

How much heat?

[ducpainter]

A hammer driver is better than an impact wrench?

It is less brutal on the bit...

and also directs the initial force downwards and in a twisting motion.

It's almost always worked for me on the older allen style screws.

You broke two torx bits or two rotor bolts?

I briefly torched my rotor bolts with propane and then whacked them a bit with a hammer driver (basically just what ducpainter said).  I made sure to use a good quality 3/8" torx bit socket.  All of the bolts came out with very little drama using a regular ratchet.  My bike is rarely outside, so I probably had it easy due to lack of corrosion.  I reassembled with a drop of blue loctite.

I broke two torx bits.

Try some brief propane and/or a hammer driver.

I bought a Lisle brand driver from Chris and used a new Craftsman 3/8" socket torx bit (bit itself is hardened + black oxide coated).

The stock rotor bolts sucked on my 695.  They were mild steel and stripped out under a normal amount of force.  That's not the half of it though...  We cut, sliced, hammered, drilled, torched, sprayed, and god knows what else for about six hours before we finally got them all out.  Not one was reusable.  I decided to go with the extra strength (and expense) of titanium this time so I don't have to deal with that again.

What a nightmare you had there!  I guess I got lucky, because my M695 rotor bolts were no problemo using the methods described above.  I had heard about potential issues, so I tried to go into it well prepared.  School of hard knocks and all...

I actually obtained stainless steel button-head replacement rotor bolts, and used them to assemble the new rotors, but before the loctite cured I had second thoughts and decided to reuse the stock black bolts instead.  Their Torx design provides extra surface area/grip for torqing things off, and I was anticipating the next rotor changeout...those little 4mm allen fittings on the SS bolts did not look too stout anymore.  Good call on the Titanium!

I'v taken mine off with no problem using just a craftsman torx socket and ratchet.

After removal, it was apparent that some sort of threadlock was used.

Heat gun followed by hammer-type impact driver with socket torx = SUCCESS!!

Thanks Nate!!
