Brake Rotor vs High Speed Cutter

[DaCan23]

Heres what I had to resort to after the rotor bolt got stripped about half way out... the high speed cutter was the last resort but it did the job... oh the frustration.....

that looks like a crapy day were you able to get the bolt out after all that good old vice grip action?

After using several different bits, then drilling it, then having a bit break in the drilled hole, and many other failed attempts, I used the high speed cutter to eliminate the bolt head, rotor came off and then what was left came out easy.

wow... make sure you use anti sieze on the new bolt, and torque it at its unnaturally low spec!

For a few years I have been using Walter Rock 'n Roll ceramic-based anti-seize compound.

It's certainly the best of the anti-seize compounds I've tried. It is quite a "dry" formulation, and since it's ceramic-based there is no galvanic corrosion to be worried about. Temperatures of 1400C (2500F!) do not bother it (thus it is perfect for brakes) and when in service it acts as a sludgey powder in the space between threads (rather than as metal particles suspended in grease as Nevr-Seez and the like).

Here's a link to the Walter site giving details:

I get it from Acklands-Grainger industrial supplies but it is also available from a number of online retails such as Etox, etc. (click the photo above to see the Etox site)

Anyway, I really like the product and recommend it highly for rotor setscrews (and other threaded fasteners exposed to hostile conditions and that you want to be able to get off later.)

Enjoy!

p.s. - Walter has two great bolt-removing products as well: Cold Shock bolt-release and Bolt-Out penetrating lubricant. I also recommend these highly - particularly when trying to remove the fasteners you didn't use Rock 'n Roll on when you put them together... :)

going to replace the rotor anyway you can just take a large hammer and whack the back of the rotor on the opposite side of the rotor from the screw, hitting it there will break out that thin amount that the hold down screw fastens onto and then you can grab the screw with vicegrips after the rotor is off. Takes only a few seconds this way. I've had to do it to a number of them that were brought to me already chewed up
