2003 Lexus GX470 Front Ceramic Performance Brake Pad & Rotor Kit TRQ Performance BKA12673

Hey, friends. It's Len here from 1A Auto. Today we're going to be working on our 2006 Toyota 4Runner and I want to show you how to remove and install front brake rotors and pads. As always, if you need these parts or any other, check us out, 1AAuto.com. Thanks.

Okay, friends. So it's time to remove our wheel. To do that, you're going to remove all of your lug nuts. Going to use a 21 millimeter socket. If you're going to be using a ratchet, it might be easier to do this while the wheel's still on the ground so it can't spin while you try to loosen up your lug nuts. I'm using an air gun, so I've got my eye protection, my hand protection. Here we go. This one I'm going to leave on a few threads. Put my lug nuts there. Now I have a spare hand. We'll try to wiggle this around. A lot of times on Toyotas, they don't want to break free right away. That's not really that big of a deal. You could use something as simple as a rubber mallet or if you have a pry bar. Either way, what you want to do is make sure you have a lug nut on at least a couple of threads, but it's still nice and loose.

Come right under here, I'm going to bonk right on the edge of the rim. If you're using a real hammer that's not a rubber mallet, definitely don't hit your rim. You'll mar it up, cause issues. You can try bonking on the tire. You just have to be careful because when you bonk, it's going to want to come back. Rubber mallet, right on the rim. There we are. That lug nut did its job, made it so the wheel didn't come falling off and hurt anybody. Super important, safety's number one. Take our wheel off and we'll roll it out of the way.

ll right, so we're going to take out this clip right here. Just a little forky looking clip does this and it goes right over the line. I'm going to use a screwdriver, small pry bar, some cutters if that's easier for you to grab with or even pliers. Once you get it so it wants to break free, should be able to wiggle it right out of there. And that's what it looks like. It's got a little ear here, and that ear faces towards you or away from the vehicle. Set this aside.

Okay, so now it's time to take out these caliper slider pins here. Sometimes they'll be frozen in there if your caliper's old, and that's pretty common. But basically what you need to do is grab like this, your small pocket screwdriver, you're going to take off this clip right here. And do the same thing to the other one. Pull off that clip. It's the same as the first. You don't have to worry about mixing them up. Awesome. Now what you would need to do, just take your small hammer, give these a couple bonks. These ones come out nice and easy because it's a brand new caliper.

But if it wasn't and they didn't come out easy, you just use your hammer, bonk, bonk, bonk until it's level. Take your punch, drive these all the way through as far as you can, and then come from this side and pull your pin all the way out. You'd want to inspect your pins and make sure that they're not rotted or rusted or anything like that. If they are, you'd want to replace them so they look something like this, nice and smooth because your pad needs to be able to slide around on them nice and easily. We'll set those aside.

We've got a little clip up here. This comes out very easily. Just got a little ear right there and it slides into the hole on the pad. And then same thing over here. At this point, if this wasn't a brand new caliper, your pistons are going to be holding your pads probably up against your rotor. We'll go with the assumption that they are, you would take your small pry bar, just come right between the rotor and the pad and just try to push like this. And that's going to slowly push in this piston. Same right here, over here and over there. Once you have it so your pistons are pushed back and your pads are plenty distance away from your rotor, you can grab your pad, slide it right out of there. We'll set that aside for recycling. This one. Awesome.

Now you're going to want to make sure you have maybe something like this or even a small bungee cord, whatever you need, because we're going to be taking out the two mounting bolts that hold this caliper to the knuckle and we're going to have to hang this somewhere, so just get it ready. Wherever you think you can probably put it. We're going to take out those two bolts and we can continue. Now I'm going to use a 17 millimeter socket. This one's just a swivel and it's on my impact wrench and that's just so when I come in I can get the right angle. You can use a 17 millimeter socket and a long ratchet if that's easier for you. Of course, if you're using your air gun, you want to make sure you're wearing safety glasses at all times.

Got both of our bolts and set these aside. Just grab this, bring it down here. Should be able to move around fairly decently. I'm just going to put that there. There's no pressure on this flex hose. You definitely don't want to put a tug on your flex hose.

When you're trying to take the rotor off. You'd want to have a lug nut on there, at least a few good threads, and then when you're taking your hammer and you're going bonk, bonk, bonk to try to get this to break free, if the rotor did decide to pop off, and it can't come down and potentially hurt you anywhere. This rotor's already broken free. Here's our rotor.

Okay, friends, so it's time to clean up our wheel bearing hub here, and this is the surface that our rotor's going to be resting against. You can go on 1AAuto.com and get yourself one of these tools, which is a wonderful tool. It has a little sanding disc on here, and of course you would wear safety glasses and hand protection, but when you give it a little juice with air, of course, the sanding disc is going to rub up against here and clean it up nice.

Let's give it a try real quick. I'll show you what it does. As you could tell, that works really well. If you didn't want to go on our site and get one of these tools, you can get yourself one of our quality 1A Auto brushes. This just has some nice little tines on there for you. You would just take it, go like this, get it as clean as you could. I could spend more time, probably get it almost as clean as this. That looks pretty great. Practically new I'd say. Actually it is new, even better. If you want to see the video how to replace that, check it out.

All right, so we're just going to clean up our rotor here. A lot of times brand new rotors come with a coating on them that just helps prevent rust and anything really from messing up the nice, beautiful surface that they made. I just like to take a little bit of parts cleaner, give it a little spray, and wipe it down. That looks great. I'm going to grab some copper never seize, I'm just going to try to spray the base of this. That's right where the rotor's going to be mating up against. The reason for that is it's going to help keep moisture out of there and also make it so the rotor's going to come off easily when it's time to take it back off someday to do another brake job. Take this. Awesome.

Now's a great time, before we get the caliper on here, just to double check and make sure that the backing plate hasn't been bent in, because if it's hitting up against the rotor now. It's obviously going to hit up against the rotor later. Give it a little spin. That sounds horrible, so let's check it out. Carefully give it a little push. Obviously there are some sharp edges. Your backing plate may or may not look like this, but if it has sharp edges, I want you to be super careful. Just going to take a pry bar. Just try to help this backing plate along. It's seen its day. It's obviously not in the best condition, but just keep working your way around. Find all the places where it might be hitting and just maneuver it away a little bit. Looks like it's hitting just a teeny bit right down here still. Ooh, love it.

Okay, so now it's time to mount the caliber. And whether you have an old caliper or a new caliper, you're going to need to prepare it. If you have an old caliper, what you're going to notice is it's more likely going to have rust right along here and here and here and here, and the same on the other side. Basically, right where the pads are going to ride, you're going to notice a lot of flakes of rust, so you're going to either need to scrape them or you can use a brush and clean them up. Just try to make them as smooth as possible. Once you have them as smooth as possible and you're sure that all the rust is clear from there, you're going to use a little bit of caliper grease--something like this. It's nothing special. You're going to put a couple little dabs right along those spots where the pads are going to ride. All four--boom, boom.

Next what you're going to do using the same caliper grease, you're going to go right on your pistons. And essentially what we're doing here, to make it short and sweet, is lubricating any areas where the pad touches the caliper. That's going to help with vibration dampening, noise reduction, and of course it's going to make a nice area for the pads to move around. Assuming you've got your caliper all nice and clean and dressed, we can continue.

Now we're going to take our caliber--bring it right over here. Work it right down. I know what you're thinking, who puts on the caliper without putting the pads together first? Well, you can think that if you want and that's fine. I'm not going to get mad at you, but I'm going to show you why. We're going to get this all together. We're going to get it torqued down and then we'll install the pads. I'm going to to grab my ratchet with my 17, snug it up, I'm going to bottom both these bolts out and we'll torque them down. Torque specification for this is 91 foot-pounds--Torqued and torqued. Awesome.

Now it's time to get the brake hose back into the bracket here and you might notice that when you were hanging it or whatever happened. Maybe the line straightened itself out or it changed its position or as we move this around, start noticing that it gets kind of close, which is good. Just going to try to spin this now. This forky is going right through. It's got this locked in perfectly. We don't have to worry about our flex hose moving around. I'd say that looks pretty great. Let's move along.

It's time to grab our pads. We've got our wear indicator. We already matched it up with the pads that we removed out of the vehicle, so we know that this is where it's going to be. The wear indicator, it's going to go on the inside. We're going to take our pad and slide it right in--just like this. That's cool. Same thing with this one. It should slide right in. If for some reason your pads don't slide in like this one does and it moves around very freely, odds are you still need to clean up your caliper a little better. Obviously this is a new caliber, so it's going to slide perfectly, but if it wasn't, and it was an old caliper and we tried cleaning it up with our brush and our screwdriver or whatever you use to get off the large chunks, if the pads can't move, you got a little bit more work to do.

To continue, I'm going to grab our pins and go through like this. I'm going to leave that one just like that. This one--I'm just going to go all the way through. Cool. Grab one of my little clips here. Go through this one. That feels great. Can't fall out. Awesome. The reason why I left this one like this, just because we got this little clippy-do here and what this is going to do is it's going to want to separate the pads. When you step on the brake, the pistons are going to squeeze the pads and then you release the brake, the pistons are going to want to go back in and this is going to make the pads go back out. Very nice. I'm going to go right over the pin just like this. Now I'm going to take this here, put it in, and everything's lined up great. Grab my other little clip and slide it through. Awesome.

Next what we're going to do, we're going to make it so this little piston goes inside the hole there and this ear comes up over the top of the pad. The same thing for this one. Awesome. Now let's assume we're inside the vehicle and we step on the brake, we release the brake, step on it, and release. That's doing its job. Something to pay attention to is when you mount this in, you want to make sure that this area of the clip isn't hitting up against your rotor. It's very possible that maybe it's bent a little bit and it wants to hit like this one is super close. What I like to do at this point, just grab it, and give it a little tug. Now I've got a pretty good distance between there and there. Just give it a little push. It goes back down. Let's try it again. Give a little push, goes back down, but it's still clearing the rotor. It's not hitting at all. At that point it looks perfect.

Now we're going to grab our wheel. These wheels can be heavy and I don't want you to hurt yourself, so instead of grabbing your wheel like this and trying to lift with your back and potentially hurting yourself, show you a little secret. You take your leg, I'm assuming you're not worried about your pants getting a little dirty. I'm just going to grab it like this. Roll it right up your leg. Now you can use your legs slash ab muscles to lift it right up. Use your leg to hold it. Balance it. See, that works pretty good. I'm going to take my lug nut, my socket. Put it right on here. Now that we know we've got one locked in, we can release it. Grab the rest of our lug nuts. We're going to start all these on. We'll bottom them out and then we'll torque them down.

All right, so let's bottom out these lug nuts. Perfect. We'll get this down on the ground and we'll torque them down to manufacturer specifications. Okay, friends, let's get our torque down. We've got our 21 millimeter socket. We've got our torque wrench set to 83 foot pounds. We're going to go in a crisscross manner. I'm just going to go around one one more time. It's a small price to pay for safety. Awesome.
