Hi, Investigating the gringing noise from the rear brakes on my Mk2 Alhambra, I've found that one of the sliders (the bit that seems pressed into the carrier) has copmpletly rusted up and in trying to loosen it I've managed to shear it off. Does anyone know how to remove the slider part from the rear caliper carrier? Is it a case of hitting the protuding lip with a punch to force it out (although it seems too corroded in for that) or is there some other clever method. All this, of course, is assumuing that it is replacable in the first place. Many thanks P
