Doing a brake job and are stymied by how to unscrew those pesky little screws holding the rotor on? Phillips head screws, right?

WRONG! Using a Phillips head screwdriver will most likely "cam-out" the head on these. Then, it's cussing and breathing fire....

Learn the secret: they are Japanese Industrial Standard (JIS)--B 10-12 cross head screws. The proper bit is the one on the right! (usually $5 for all three at local motorcycle shops or on-line.)


an $18 tool or a $5 bit set solves the problem--or a 2mm drill. Don't ask me how I found all this out.

"The JIS B 1012 is commonly found in Japanese equipment. It looks like a Phillips screw, but is designed not to cam out and will therefore be damaged by a Phillips screwdriver if it is too tight. Heads are usually identifiable by a single dot or an "X" to one side of the cross slot.Specific "JIS" standardized cruciform-blade screwdrivers or 1/4 inch drive bits are available for this type of screw." source: Wikipedia

Yep! Thanks for the re-post, Tyson! I've learnt the hard way about those pesky rotor screws. Here "up North" they dump tons of salt, liquid brine, and calcium each Winter on the roads. Good for roads, horrible for metal parts--especially bolts and nuts. You learn quick that upon re-assembly, that 'anti-seize' is your friend for future jobs.
