Thought I'd share my experience of changing the rear brake pads.
Mileage 102000, pads down to about 2mm about the thickness of a 50p piece. Original pads.
Should be an easy job ? Wrong. Dismantling is easy enough, the outside pads come out and slot back in no problem. However the inside pads are a different story, the original pads would not come out without the use of some sort of lever (I used the flat end of the wheel brace), and then the new pads would not go in. Tried putting the original pads I'd just taken out back in and they wouldnt go in either ! In the end had to hammer the new pads in.
Went for a test drive and everything seemed fine but on checking the disc noticed it was hotter than it should be, as if the pads were rubbing/binding. So I stripped everything down again but this time took off the caliper part that the pads sit in so I could make sure the pads were in place properly.
Here's the issue, the inside pads are a VERY tight fit, they will not slide in without hitting with a hammer or similar. Again compared to the original part that was being replaced and these were the same. My advice if diy is to remove the pad holder and fit the inside pad off the car, that way you know it is fitted correctly, trying to do it on the car you cant see if its lined up properly unless you have a ramp. Overall I'd say buy the parts and get a local garage to fit them for just the labour cost which shouldnt be more than around £20. Let someone else have the grief !! It's as if the pads ( new and old) are just slightly too long, 0.5mm less and they'd slide in no problem. Thye do go in but it takes some force, you can't do it by hand.
If you do want to try it yourself you'll need;
13mm socket for the caliper
14mm socket for the pad holder
Brake piston rewind tool, clockwise for drivers side(RHD), anticlockwise passenger side. You can 'push and turn' without the tool but it's very stiff and needs a lot of push pressure.
Wire brush for cleaning
Lever and hammer to remove/replace inboard pad.
