hi all, sorry i havent replied sooner,
Sticky caliper would be correct, went for a spin, and something didnt feel right pulled over, wheel very hot, so pulled up to a supermarket, went for a walk let it cool down,
I used some tools I keep with me, to give the caliper a whack, and i also pushed the piston back slightly, (with difficulty). Anyway, drove home no Issues, went to work today, same again hot wheel,
Ive ordered a new caliper, and will be getting it fitted asap,
Thanks All
