Not sure that it's worth spending anymore time trying to extricate the blasted brake pad securing screws, so looking at the possibility of new calipers.

Is there a list anywhere of calipers which will fit (and stop the bike)? I've been trawling the internet for CM068316 and 317 calipers and have noticed that a lot of other calipers advertised for other models look very, very similar.

If you are going to the trouble of removing the callipers I would be inclined to strip out the rubber parts, cut the pads free with a Dremel, then use heat on the calliper body to loosen the threaded part.  I made the mistake of trying to do the rear calliper in situ and drilled out the pins. Although I did succeed in the end it would have been far easier to start by taking the calliper off.

The issues with these calipers is mainly two fold, 1 they use a too high strength thread locking compound, 2 it's cheap s/steal into aluminium.  Normally heat will do it but as with everything there's heat and there's heat!  Most try and are successful using butane DIY plumbers blowtorch, but these don't burn hot enough for the stubborn ones.  They just end up heating up the whole caliper, possibly wrecking the seals and not softening the compound.  What you need is acetylene just on the pin, it's so hot the heat goes straight down the pin and softens the compound in seconds, not enough to damage anything. 

The other way once you've buggered the caphead, is to spot weld a allen key into the rounded off caliper pin, the heat from the weld softens the compound and the key which is now welded to the pin will with a socket get the pin out.  You don't need to attack things with Dremels, obviously you need access to acetylene and or a welder.  Both should be accessible at a local car workshop, just explain and if they give you funny looks, go elsewhere!

In both cases as mentioned take the caliper/s off.

Once they're out fit new and a little dab of chopper grease on the thread.

If possible I would like to find an engineering works and give it to them? Such firms have been useful to me in the past and I think in every case they had a solution that I would never have thought of, or were able to use a technique I never knew existed.

E.g. there were at least 2 cases of bleed nipple snapped off in a caliper, which were removed by an arc erosion machine.

Hi
Should anyone be "breaking" (hah!) an X10 I'd be interested in both front calipers for sorting over the winter (I'd do the ones on it but don't want the bike off the road too much as it's the winter ride.
TIA
