There is a 1 inch steel sleeve stuck in the lug of the caliper.
I have soaked it in penetrating oil,
I have tried loads of gentle taps,
as well as some mightly 2LB club hammer ones.
I also tried a bit of heat, maybe I'll try that again with a load more..... but I dont want to fry or melt the cable rubber or plastic inner liner.
I made up an insert to go inside the end that needs to be tapped out, the white one,
and I also made up a sleeve to rest on the lug of the caliper to seat it.
Currently I have an OHC valve compresser round it all applying pressure, while it soaks in oil too.
ANY help or suggestions much appreciated.
