Seems a simple task.

Remove pad pins on front brake to replace the pads.


OK, but what is that pin head?

12 point, yes.

does my 12 point 6mm fit, oh no it doesn't, too small.

nor does my 7mm, too big.

1/4 inch 12 point, no too big.


It's like Goldilocks.


What fits?

Its a 2004 FXSTi

The pad pins are 1/4 inch 12 point, I got mine from Sears, but I would think any decent automotive tool supplier would have it. In a pinch you could use a 1/4 inch 12 point closed end wrench, these are more common.

Push the pads into the caliper assembly when you are screwing out the pad pin bolts, this will unload them from the anti-rattle spring, which makes them hard to screw out.

I wonder why Harley uses a 10 mm 12 point to hold the caliper on and a 1/4 inch 12 point for the pad pins? Mystery....

The forks are made by Showa and so are metric, while the caliper supplier is most likely U.S.A.

Sorry, but everytime I see this topic title I think it says 'Brake Bad Pins,' so I think of some poser in a vest with pins that say 'Bad To The Bone,' 'I'm a Bad Man' or 'Pain Don't Hurt.'

Yeah, I know it would be 'break' not 'brake.' Can't help it.

I have changed those pads on a couple of bikes, and they are a pain in the ass. I dont remember what size wrench was needed, but even after I got the right size the bolts were so soft that the heads stripped off. I ended up going to the dealer and buying a set of replacement allen head bolts. They are chrome bolts sold at the dealer and they are a lot easier to work with than the stock ones.
