Begin by placing the vehicle on a flat surface with the parking brake applied. Loosen the wheel nuts/bolt on the first wheel by about half a turn (no more).
Raise the vehicle. If you are using a jack it is essential that you use an axle stand or suitable support as well. I'm using a vehicle lift but this is a straight forward job on the floor with jacks.
Remove the wheel nuts/bolts and lift off the wheel. Note: sometimes a bit of corrosion can make the wheel stick to the hub. In this case, make sure all bolts are removed and use mallet on back of rim.
If you are just changing the pads, skip this step. Now you need to loosen the screw that retains the disc. Wedge a screwdriver inside the vents of the disc to prevent it turning whilst loosening.
Now you need to remove the brake caliper. Turn the steering so the Caliper points outwards for easier access. Remove the spring retainer from the front of the caliper using the screwdriver.
Now remove the two plastic plugs from the back of the Caliper (by hand) and then remove the two Caliper slides using the 7mm Allen key.
Now the Caliper can be lifted off (you might need to prise it a little) and you can now remove the pads from the caliper (sometimes they stick a bit, you might need to prise them also).
Now you need to support the caliper so that it doesn't hang from the rubber hose. Use a piece of wire or string to hold it up. Note: this is best practice but I never to this, these pipes are strong!
Now to remove the caliper carrier you need to remove the two 16mm bolts. These should be really tight. You may need the bar you used for the wheel bolts. Loosen them both before removing one.
Ok, unwrap a new disc and give it a good clean and degrease using the brake cleaner and a rag. It is important to remove all traces of the protective coating.
Now you need to be cleaning up the carrier, specifically the places where the pads locate. Use the small file to clean the slots out thoroughly. I've cleaned and painted mine (not necessary though)
Ok re install the carrier and tighten the 2 16mm bolts up nice and tight. Make sure none of the grease has found its way onto the disc surface, clean with brake cleaner if necessary.
Now you can stick the screwdriver into the vents again and tighten the disc retainer a little more.
Reinstall the two slides, tighten and refit the two plastic covers. Now refit the wheel and tighten the bolts as much as you can. Now enter the vehicle and depress the brake pedal several times HARD!
Get back out and check the wheel still spins freely. If it does, lower the vehicle and tighten the wheel bolts thoroughly. Proceed to the other side and repeat the job.
Remember to observe any bedding in procedure. Generally this consists of 200 miles gentle driving whilst the disc and pad surfaces mate properly.
Recheck the tightness of the wheel bolts after 100 miles driving. Enjoy your new brakes. Hope this has helped. Good day.....Dan
