hand brake on ,loosen wheel nuts,jack up car and place on axle stands.remove wheel.blind side of caliper there are 2 bolts fixing caliper to mount ,remove them(very tight).dont stretch brake hose.place to one side.the disc will be held on with a philips head screw on front by wheel fixing holes.remove this and disc will pull off(may have to give it a tap).clean mount and fit new disc,refit philips screw.take spring clip off brake caliper ,note how it goes back on.remove pad,prise other pad out of brake piston.check piston etc for leaks etc.i usually lightly squeeze the piston back into caliper,this eases refitting to disc.fit pads into caliper,use special grease as req'd.fit spring clip.slide pads back onto disc and fit caliper 2 bolts,torque bolts up.give every thing a clean.refit wheel,put car back on floor and tighten wheel nuts.pump brake pedal until it feels normal.check brake fluid level .always renew as a pair.hope this is of some help .
