ok...jack up prospective side
1) take wheel off
2) remove caliper spring (ensure you remember its orientation !!!
3)locate the 2 bolts that hold the caliper halfs together (2 horizontal bolts, but NOT the ones that hold the caliper to the disc)
4)possibly the pistons will need careful prizing to allow the outer pad to slide off with caliper half.
5)the inner pad should be removed
6)carefully retract pistons using g-clamp or similar device(may need slight cutting down to fit).
7)slide inner pad in to place,position outer pad on removed caliper half and slide in to position,may need slight tap to locate.
8) fit bolts and spring in original positions.firmly jiggle caliper to ensure sound. outer will rock slightly about the spring.
9) pump brakes a few time to ensure correct function of brake system.
10)wheel on and take off jacks
gentle braking while bedding brakes in....although firm but not prolonged braking should be ok if needed ! as should be stated on the new brakes box !
this is as best i recall, if in doubt post again with the problem...
good luck.
