Use a 13mm spanner to undo both the bolts on the back of the caliper frame. You may
need to hold the other side of the bolt receiver with a 17mm spanner to stop it spinning.
Removing 1 bolt allows you to swing the carrier up but may not be enough to get the pads out.
With both bolts removed, slide the carrier away from the caliper.
Rest it on top of the brake disc or tie up out of the way. Do not let them hang by the pipe.
Pull the nearest pad towards the rear of the car to remove it.
Now pull the rear pad in the same direction. Note the rear pad has a metal tab.
Refitting
The new pads will be thicker than the ones you have removed. Open the brake fluid container and push the caliper piston in all the way.
When refitting the pads, make sure you have the metal tab on the rear pad.
A dab of copper grease on the back of the pads can stop pad squeal.
When closing the caliper, make sure both of the pad springs are properly positioned.
If they are incorrectly positioned you will see the spring protruding through the inspection hole.
Do the 13mm caliper carrier bolts up tight, you may need to hold the
other side of the bolt receiver with a 17mm spanner to stop it spinning.
Pump the brake pedal to set the caliper pistons and repressurise the system.
Bedding In Pads
You are supposed to slowly bed the brake pads in when you have fitted them.
This usually involves long slow braking to bring the heat up.
Follow the instructions given by the manufacturer of your particular brake pads.
