1.
Chock up the front wheels.

2.
Jack her up. (I used two jacks for support)
3.
Remove the wheel.

4.
Remove clip for brake line.

5.
You'll see two bolts on the caliper. Remove them both (unlike
front brakes where you only remove one).
6.
Remove the caliper.
7.
Using a pair of pliers twist the piston head and fully retract
the piston head.
(check piston for score, rust, wear, damage or foreign materials.
Replace if any of these conditions are observed. Piston surface
is plated, do not sand)

8.
Check disc rotor for wear and score.
(check disc for grooves, wear and general roughness. If so remove
and get them machined at your local brake shop. Also measure
the width of the rotor, standard should be 10mm. If it's less
than 9mm, you have to get a replacement rotor)

9.
Remove centre screw from pad.
(mine had a shitty bolt, and needed pliers as i would've stripped
the pattern otherwise with a normal screw driver)

10.
Remove both pads by pushing the locking pins outwards and pulling
pad out.

11.
Take shims off old pads and put them on your new pads.
12.
Install new pads, close caliper over them and bolt it back together.
(If you fully withdrew the piston, you shouldn't have any problems)


13.
Brake cable goes back on with the clip we took out before.

14.
All done. Just top up your brake fluid (if you withdrew your
piston too much you may notice your fluid overfilled, it'll
go down so you can top up later).
15.
Test your breaks out now. Drive out, slowly break a few times
to make sure they're operational. Then read the pad manufacturer's
advice. Mine required 20 medium to hard brakes (ie. over 60km/hr,
obviously do this where it is legal and safe).
