As you may have read in my other thread my front calliper was dragging causing the system to get so hot it boiled which produced air and thus I lost all brake pressure. I spoke to the chap at splats and I decided to go for a complete seal kit so I have the reassurance the calliper will have fresh pistons and seals, hopefully reducing the chances of binding in future. I removed calliper and obviously the top ( longer ) calliper bolt acts as the calliper joining bolt and to attach to the bike through a mounting hole. The bottom bolt however purely acts as the lower calliper bolt ( holding the 2 halves of the calliper together) this is a 5mm Allen head and the bolt is so tight that eventually my Allen key rounded also rounding the internal faces of the bolt. Being a steel bolt in aluminium threads there is a corrosive reaction that's taken place effectively seizing it solid. Previous to the Allen key rounding I did apply heat to the threaded end of the bolt but to now evail.
I'm literally screwed as I can't think how I'm going to undo this bolt without a secure place to apply torsional pressure. Trying to weld a nut to it is going to be hard and potentially damage the aluminium body. I was thinking of drilling the head off then splitting the calliper and using mole grips on the remaining stud or place the stud in a vice a twist calliper. Does anyone know if the bolt head is stepped into the calliper body or if it sits flush on top? I see now they use normal hexagonal bolt heads so a socket can be used!!! Mine is a 2009 please people I need help I can't be the only person to have experienced this!!
