Just had an unusual "to me" mot failure the rear disc had microscopic cracks around a few of the cooling holes. I do brake hard on the back brake and these cracks are probably heat related.But still something i was not expecting. I have sourced a disc from the forum "thanks Andrew!
But trying to remove the disc the fun started.Before attempting to remove I tapped all the relating bolts with a hammer but still the centre ripped out of two of the allen retainers. I then removed the allen heads with my angle grinder , this got the disc of the hub, but left me with the remains of the stuck bolts to remove. despite heating the alloy hub with a blow lamp , they are still stuck , not much for the mole gripps to hold now!
drilling them out is going to be difficult as they are very hard. oh well i'll see what tomorrow brings ,might try and find somebody with a oxy torch
to get more heat on it
