Stupid brake question
So I am mounting cbr600rr brakes onto 05 zx10 forks. Which bolts do I use? (caliper ones or fork ones). The cbr bolts are 10x57, the zx bolts are 10x60.
Which ones and why. Only concern is whether there is enuff depth in fork thead right?

Oh yea, there are no stupid questions when it comes to safety

As you`re dealing with radial brakes and the bolts are being screwed into aluminum (bottom of fork leg), I say use the longest ones possible that do not bottom out, thereby ensuring maximum grip and penetration....

Use the longer bolts if they will thread though the caliper mount and into the fork leg fully.. if not, use the shorter
For steel, a basic rule of thumb for thread engagement length for a screw in a tapped hole should be 1.5 the Diameter, where Diameter is the major diameter of the screw.
I've also seen it suggested engagement length of 1.0D for steel, 1.5D for cast iron, and 2.0D for aluminum.
I try for 1.5D in any steel and use 2.0D in any non ferrous metal.

measure the caliper where the bolt goes through with a micrometer if you have one (if not they are cheap enough, its a priceless tool Digital Calipers - Save on these 6 Inch Digital Calipers) if the ZX and the CBR calipers are the same size where the bolt goes through use the longer bolt, if the CBR is a few mm narrower than the ZX use the shorter bolt.

Yeah, I am using the longer bolt, but dont have all components of each to do any measuring. Mikstr, we typed our entries simultaneously(look at the times), I was refering to NHSH about hitting the rotors.
I cant know the caliper thickness difference but hope 3mm cant make it bottom.
