First look at the rear brake caliper .
Along the bottom , holding the brake pads in is a small angled metal bar about 30mm in length with a spring retaining clip in it . Pull the small spring retaining clip out with some pliers .
With the retaining clip removed , get a small flat blade screwdriver or punch and tap the angled metal bar out , towards the outside of the car . It might be a little tight with rust , dirt etc .... now keep put the clip and bar somewhere safe .
Next , push the pads upwards and pull them out from the bottom , you might need to pull them out with pliers because the spring clips on the pads are holding the pads in .
Unclip the spring clips from the pads and keep them safe , you will need them for the new pads .
Now wind the piston back into the caliper clockwise using a flat bar or small screwdriver , to make room for the new , thicker pads . On the piston , make sure you leave the groove level so you can slide the new pads back in . On the back of the pads you will see a small lug , this must line up with the groove on the piston .
Clean up both the top and bottom surfaces on the caliper where the pad and spring clips will sit and the 30mm angled metal bar , if you don't you might struggle to get the pads back in .
Put the old spring clips on the new pads , like you see in the main caliper picture .
Make sure that the clips are under the t shape of the pad and also they must sit on the flat surface of the pad mounting bracket .
Now you have to push both pads upwards ,you will feel some resistance as the spring clips are pushing the pads downwards .You need to do this so you can slide the small angled metal bar back into the mounting bracket , tap it with a hammer .Now replace the small spring retaining clip , pump your brakes then bleed if you need to .
