Before you do the job, you have to take off the wheel. To do that, you need to get a 22 millimeter socket and usually a half inch breaker bar—or you can use the lug wrench that comes with the vehicle; either works. We'll just crack these loose before we jack up the vehicle, and that'll make it easier to take the wheel off in a few minutes.

Now you want to raise and support your vehicle. You can definitely use a jack and jack stands in a drive way. To make it a little easier to film, we're going to be using a vehicle lift. Make sure you use the proper spots on the vehicle to jack it up, which we have another video for. Now we will take the rest of the lug nuts off. We already loosened them while they were on the ground, so this step is really easy. Once the lug nuts are off, you can lift the wheel off the car.

It's not actually necessary to remove the caliper and caliper bracket from the knuckle and the rotor, but we had them off because we were doing the whole brake job. So in your case, if you're just doing the parking brake adjustment, you don't need to take any of that off, you can leave it right on and just remove this plug and get in there with a flat tipped screwdriver.

Right here is the rubber cap that blocks the hole that gives you access to the parking brake adjuster. You want to do to adjust the parking break by putting a flat tipped screwdriver into the hole with it, just about at 12 o'clock. At that point you can spin the adjuster wheel up. So you want to start off with it down and lift up. Do it a couple times just like this. Then spin the rotor by hand, and you want to just barely hear the parking brake shoes touch the rotor.

So we'll do it a little bit more. So as you adjust it, you want to give it like a turn or two and then turn the rotor and as soon as you hear the parking brake shoes touch the rotor—that's when you want to stop, because that's when they're just about out enough to actually work really well. So at this point, I can hear the shoes touching the rotor, but the rotor still spins freely, so now I can put the rubber plug right back in the hole, and that protects it from water intrusion. It'll slow down the rust that goes on inside there.

We're now at a point where we can put the wheel back on, and we'll loosely install all of the lug nuts by hand. With the vehicle back on the ground, you can torque the lug nuts to 125 foot-pound. Make sure you do it in a star pattern.
