Should be what aluminium holder. So you want some plus gas and WD. I personally wouldn't touch it until it's been nicely soaked through with WD and Plus gas. Do a few heat cycles with a heat gun on LOW setting. Just allow the WD to penetrate properly.

Then use something like an Impact Drive to slowly drive the bits out without rounding them off. A slow process if you need it done quick.

What bit are you trying to remove anyway.

Take the pads out and soak everything, that caliper looks older than what I took off an 89

Healthy dose of WD and a bit of prying should work i'd think. I destroyed 2 sets before I used WD and it sorted it first time

Definitely or you'll just end up rounding them off then it's a whole other ballgame. Try covering the pads as much as possible too, WD soaked pads are no fun, trust me lol

Will you be removing the piston?

I'm not sure I had to remove everything, piston, rubber seals etc because the bike hadn't moved since the 80's lol

If the piston is moving it should be fine don't go there just get the other bits and bobs off and give it a good clean confuse

Yeah those were no fun at all, I soaked and soaked and eventually broke 2 sets till it finally worked biggrin

Try applying heat like Callum said but careful of the seals?

Mate if you're still struggling definitely take your time on Those. Apply a little heat to the bolts then lube with wd. Then apply a little more heat. Then lube with wd. Let it cool. Apply more heat than the last two attempts and take an impact driver to it. Using allen keys will most likely round those clean off and then you'll need a new calliper. Been there done that not fun.

If you don't own an impact driver then get one. Seriously mans best friend in the garage.

would at least take the caliper of the break line so you can clamp it to work on ..

they look well rounded off .. take it all off remove any rubbers and spry it to death in wd40 if need be put in a clear bag and leave over night . as said above heat can help free things up but remove if possible anything that may burn ..

I have done all kind of things to free things up even placed in pan of boiling water on the cooker .

with a good soaking in penetrating oil and the correct tool along with clamping the caliper in a vice they should either come free or snap ok if they do not snap flush as you can grip the stumps and turn them out but if they snap flush its drilling time .

this is a good lesson to check and lube-wd40-grease bolts screws and nuts once a week or month along with losed and tighten them to keep them from setting solid .

like exhaust bolts/nuts take good care of them as you will need to take them of at some point and in most cases when they lock up they snap .

The wonders of WD40... 24hrs and itll free up almost anything, and if that doesnt work, the only soloution Ive used on pistons of all types (in this case V16 2 stroke detroit diesel) heat the hell out of the bore and piston then hit the piston with Freon ( freezing cold airconditioning fluid) high pressure direct from the bottle, and pop the piston shrinks instantly and its free.

I know your pain with these pins.

A guy at my work got one of mines out. He is a yoda of engineering though lol.

What he did was he drilled a dead straight pilot hole with this special short drill bit.

Then he bored the pin head out with bigger bits till it was about a mm thick at the threads.

Punched the pin back the way out the hole.

Tapped the threads in on the remaining husk thus threading it out lol, all by hand on the bike.

Didn't even bother with the second one. Just ground the lobes on the pad so they can squeeze in with just one pin removed.

I always remove the pin now and give it a good copper greasing regularly.

Hope this helps, was the only way in the end before the calliper was binned.
