How to: Replace disc brake and pads on rear axle

Step 9: Now you have to put the caliper back on but you'll notice this doesn't fit at this time. The reason is very simple, every time you brake you wear your pads a tiny bit. As you do the piston in the caliper will come outwards.
With fresh pads the piston is to far outwards to fit, it needs to be pushed back in. With front calipers this is easy, just push them, but with these rear calipers the handbrake mechanism makes this impossible. Instead you need to turn them clockwise to get them to retract.

There are specials tools for this which you can best use. We dont have the special tools so we did it with a gripper. This is a bit dangerous as it can damage the dust cover, and that is something you do not want.

As you can see on the piston there are two indentations. These are used by the special tool but they also grip into two little studs on the brake pads. So you must make sure that one of the indentations points towards the brake pads.
