Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

Start off by loosening up these 22mm lug nut covers. We'll fast forward as Don does this. Once those are all loosened up, you can pull the hub cap free. Now, you want to loosen the lug nuts preliminarily, raise the vehicle and remove them the rest of the way, unless you have air powered tools.

You want to remove these two T55 Torx bolts. We'll fast forward as Don does this. Using a large C-clamp, just put it back behind the caliper here, and the other part right here on the brake pad, and just twist this in, and this going to push your caliper piston in and make it easier to pull the caliper off. Then, just remove the C-clamp, and lift your caliper up and off. Set it aside.

Now, using a flat blade screwdriver, just pry out your brake pad, and sometimes the pad is going to be stuck in there, you can use a flat blade screwdriver and hammer to pry it free. Now you want to remove these two 18mm bolts on your caliper bracket, and you can see, we use a piece of pipe for some extra leverage here. We'll just fast forward as he breaks the other one free and removes both of these bolts. Now, slide the rotor off. We'll fast-forward here as we just remove the clips that hold the ABS harness to the frame and steering spindle, and then there's a clip that holds the harness together, so just pull the clip back and disconnect it. Now, using a flat blade screwdriver and a hammer, just pry off your hub cap. You'll need to remove the center hub nut.

A few ways to do this: you can loosen this before you take your brakes apart, have somebody hold the brakes and do it that way, or you could use a large bar and put it between the lug studs to hold it, and then you could break the bar. If you have the benefit of air tools like we do you need an impact wrench to remove it. Then remove these tree 15mm bolts. You want to just use a 15mm wrench and another wrench for some extra leverage.

You just pry out, and once you've broken it free, you can just turn it out the rest of the way with the one wrench. We'll fast forward as Don does this to other two bolts and removes all three of them. Twist the hub nut back into place just a quarter of the way, and then hammer from the back of the hub to break it free. Then remove the hub nut and pull your hub out. On the left is the old hub; on the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same.

Put your backing plate on to your new hub, and then push the hub back into place. Then just put those bolts back in. You may need to hammer the first one to get started. We'll just fast-forward as Don replaces the other two and tightens up all three of those. Then you want to torque those three bolts to 75 foot-pounds each. Now, remove this clip if you left your old one in, and then feed your ABS harness back into place, putting the clips back where they belong and into those brackets. Then reconnect your harness and clip it back up into place.

Replace that washer and your hub nut, and just tighten it back up into place. Push your rotor back into place, and then twist on the lug nut, and this will just hold the rotor in place. Turn the wheel and put the caliper bracket back into place, and replace those two 18mm bolts. We'll fast-forward as Don does this and tightens both of those out. Now torque both of these to 75 foot-pounds.

Now replace your brake pads and use a hammer if necessary to lightly tap that into place. Grease up your caliper bolts. Put the caliper back into place, and slide those slide bolts back in. We'll just fast-forward as Don tightens those up. You want to tighten these to about 30 foot-pounds. Replace your wheel, replace those lug nuts, and tighten them preliminarily. Lower the vehicle and tighten them the rest of the way. Torque the lug nuts in a crossing pattern to 100 foot-pounds, and torque this hub nut to 125 foot-pounds. Put the cap back in place and put it back in. Take your hub cap and just tighten up those bolt caps. After doing work on your brakes, you want to pump the brake pedal until it firms out, and then try a stop test from 5 miles per hour and ten miles per hour. Then you're all set.
