Okay busy uploading some more pic's concerning this subject, but in the meantime I will continue with the next thing to do, before you loosen off the brake calipers, make sure that you have some cable ties close by, if not some fence wire will also work.
Remove the anti-rattle clips holding the brake pads in place, you will see two thin metal pins, the one clip wire keep the pins in place, on each end of the pins you will see a very small hole, some vehicle's might not have this anti rattle clip, they might only have split pins through these holes instead to prevent the pins moving out and the pads jumping out as well.
I find that an old pair of side cutters works best to remove this clip or a pair of long nose pliers, if you do use the side cutters, do not grip the wire too tight otherwise it will damage the wire clip, so you have managed to remove the clip and the two pins, you can tap them out from the inside with a small round drift or an old screw driver, then use a larger screw driver (yeah it is not good to use screw drivers like this but they make the work easier and I do not care what people say about the way that most of us abuse screw drivers).
But first of all make sure that the brake reservoir is not too fill, if so you must first drain off some brake fluid you can use a long clear window washer clear piping to do this easier, basically you just put the one end into the resorvoir, suck on the other end watch the brake fluid most times it is black (most people do not have it changed every two years in their vehicle anyway) until the level has dropped below the low mark, you can drain off until there the resorvoir is empty, but make sure that you do not suck brake fluid into your mouth the stuff does not taste nice, if you do get brake fluid into your mouth, wash it out with water or beer (most chaps who work on their own vehicle normally have a beer nearby anyway) some even have Brandy and coke that will also work,
Please note if you do get brake fluid by accident onto any paint work, body of your vehicle, wash it off again with water only.
So now that you have drained off the brake fluid, use the flat screw driver and ply apart the brake pads just slightly, this will then allow you enough space between the brake pads and the brake disc to remove the pads.
Do this to both sides left and right, but place each set of pads in a seperate dish, depending on the condition of the pads
Do not judge their consition by their thickness, you have to first check that they do not have heat cracks on their surface and you must also check the condition of the brake discs as well, herat cracks and thickness as well as high spots to see the high spots you will notice blue marks on the disc surface, if you see them, rather fit new, do not attempt to have them skimmed, you will be wasteing your time and money.
So you have managed to get the pads out, now you must have a look around the back of the brake baking plate (wear some clear safety glasses) you will see two bolts that hold the brake cailper, if I remember clearly they will be size 19mm headed bolts, use a strong arm and a socket to loosen them off, once you have loosened them off, ply the brake caliper loose from the mounting point, now use the cable ties or wire, tie the caliper up above out of the way.
Photo showing the brake caliper removed, will continue with this subject.
