Couple of questions. CB500.

[Spanner1972]

That's because you've got the wrong calipers.  The older bikes had thicker discs than these new 'uns

Mike, I've got a proper caliper now, eBay find. It's a proper cb500 one. What is the correct disc thickness for the disc? Thanks.

It should be in the manual

Doesn't t give a thickness or diameter. Looked on the tinternet and various different answer to be found.

I seem to remember 7mm but I don't know from what, so...

7mm sounds about right, cb500 and 550 had comparatively massivly thick disks. Is the piston right back in the caliper? Have you got the right pads and mount? I often help the pad back into the caliper body by squashing it back into the caliper with a G clamp, protecting the caliper from dammage with a few bits of wood.

I'll try it tonight when I get home. Nice one thanks.

Forgot to say, scrub it with a toothbrush if there is any rust or crud visable.
