Bloody pin seized in caliper..

[WarnieV6GT]

When attempting what should have been a quick job changing my brake pads earlier, one of the caliper pins wouldn't budge..using various ham fisted techniques I have now rounded off the head.

I'm picking up a new pin tomorrow but I still have the offending pin stuck in the caliper.

Any ideas of how to get it out? It's a 1998 Honda 600 hornet with the 2 pot nissin calipers.

I thought I may end up having to drill it out but I don't want to ruin the caliper. I also have some screw-outs/easyouts but have never used them before ?

Thanks for any help 😊

Does it have a split pin on the other end?

Needle nosed mole grips from the inside

Assuming it's an allen headed pin, hammer a torx bit into it and turn it. They're like easy outs for shallow holes!

Otherwise, mole grips from the inside like they said.

Hmm tricky.... is it one of these:



Try the above definately first before you're too committed !

If you can get the caliper off then you could maybe cut the pin and try drilling out - a pilot hole first and then use a reverse drill bit would be good as the chances are it will comes loose and begin to unwind.

Otherwise, beg borrow or steal a welder:

Af Allen key may be a better fit than metric, or Impact driver with Allen bit

If it is one of those pins I drilled the head out of one the BSB superstock Kawasakis ZX10 front caliper (not Akys) and then turned it out with a screwdriver.

Sounds harder than it is.

Replace with stainless and use loads of copper grease.

This is what I hate about diy on anything someone else has worked on before. Those should just be nipped up at 11 ft/lb and almost come off with fingers.

If you need the bike I’d have a plan b of another calliper off eBay ready to go.

This'll get it

Also, when cracking them always make sure your hex is a snug fit...I've had cheap sets in the past that were very loose so a high chance of rounding.

Worked for me on a seized k1100 caliper

It’s a threaded pin with an Allen head yes? Same as on a VFR800.

I’d second the approach of hammering a Torx or larger Allen bit in with an impact driver, also application of a bit of heat to free things up. All easier to do if the caliper is off the bike in a vice, but that entails removing it, which probably doesn’t align with the quick job you were hoping for. Good luck!

I tried the torx bit but it just rounded off the bolt. Will try the mole grips in the morning.

Big thanks for all the help guys, really appreciated. I've got lots to try tomorrow.
