How do you install brake pads on a 2002 jaguar s type?

on the front its straightforward , just remove caliper remove old pads, push back pistons then fit new pads and refit caliper, rears are harder as you need a piston rewind tool,, without one its quite difficult to do,, basically the tool pushes back the piston and turns it clockwise at the same time , this is because the handbrake uses a ratchet which has to be wound back,, hope this helps,,
