Shimano 105 Disc Brake Pad Axles Replacement

RedClip

Can you please recommend a hardened replacement for the Shimano Y8J710000 pad axle, which fits the 105 disc brakes?

Hopefully the image below will show up.

Part number 11.

I've stripped the screwdriver slot on mine, trying to undo it.

Thank you.

Use a split pin. Some Shimano calipers come with split pins already, they're cheap as chips and do exactly the same job.

I used

A couple of mm longer than the 105 pin but makes no difference.

+1 for this.

I stripped the screw as well, it's made of cheese. The above works perfectly & is far better than the screw supplied.

I know it’s an old thread - but those of you who stripped the screw - how did you end up removing it? Thanks.

I took my bike to a local bike shop, and they drilled out the screw.
I replaced both brakes with the "cap head" style bolt (mentioned in the Wiggle link above). I think the bike shop charged me 50p per bolt. I can't remember how much they charged for drilling out the screw.

I have noticed over time, the bolts are harder to remove. Probably due to road salt corrosion etc.

Remove and clean the threads (take the pads out whilst you do this if using anything like GT85). Once cleaned and dry and free of any corrosion etc, put a tiny dab of coppaslip grease on the threaded portion before refitting. They don’t need to be really tight either, just nipped up. The circlip prevents them coming out in use.

The coppaslip will prevent them seizing due to water/ road salt/ sweat or anything else getting in there. This means much less chance of having to try really hard to undo them and the consequential screwdriver slot damage.

I drilled mine out at home and fitted a split pin which may have come supplied with the replacement pads if I remember correctly.
