Hello, John Talley here with partzilla.com. Today we're going to
change out the front brake pads on our 2016 Yamaha YXZ1000R. Not that
tough to do. Just need to get it lifted up, get the front tires off, then dismount
the calipers. At that point, we'll take a look at those brake pads, see what kind
of shape they're in, and then replace them. And if we do need to replace them,
let's step over to the table and look at the part numbers we're going to need to
pull this off. Yamaha makes your reference to a brake pad kit and you're
actually going to need two of those. One for the left, one for the right. Now it is
the same part number, you just need to remember to order quantity two. Otherwise
you're only gonna be able to accomplish half of this task. Something I
want to show you real quick: a neat little feature is there's an actual wear
limit area right here. When it actually reaches this little cavity right here, it
is definitely time to get these replaced. Now we'll take a look at the ones that
are on there now and if it's anywhere close, we're going to go ahead and
replace them. As far as the special tools, there's not going to be any required
other than, as usual, a good torque wrench. Any other tools that I use as we go
along, I'll call out what size it is that way you can minimize the trips to your
toolbox and accomplish this little task faster. So now that we've got our brake
pads ready to roll, my toolbox is open, let's go knock this thing out.
Before we lift the machine, let's go ahead and break the lug nuts loose. Now
you'll notice that I'm actually lifting up the entire machine and taking off all
four wheels. Now you won't have to do that for your particular project, but
there are so many things that I'm doing to this machine, I want to just go ahead
and lift it up and get it up in the air one time. That way I can get to each
project. The shop cleanup boy-- me-- didn't do a very good job of pressure washing
this one so let me clean it up a little bit more and then we'll get this pulled
apart. Building my own beach. I'm building an indoor beach, that's what I'm doing.
Now that we've got to cleaned up reasonably well, let's go ahead and get
the caliper off. There's only two bolts to do so. They are 14 millimeters. These
aren't in that bad of shape. They're only about halfway worn, but the whole purpose
of this video is to show you how to do this so we're going to go ahead and
replace them for you. But if yours look like this? You can keep going. Before we
can remove them, we need to go ahead and push the caliper pistons back into the
housing. And to do that, we're just going to use a regular C clamp. We'll move it
back and forth until we can get them to push in evenly.
We've got 'em compressed in, now we can remove the pads. Looking to see if these
were OEM and if they had that wear indicator on them. Yep. Looks like it.
Alright, one side out, let's see if we can get the other one to pop. You just have
to get it past what they call a spring. What I'm loosely calling a spring is
this piece of metal right here, and there's actually a duplicate of it on
the inside. What that is doing is actually holding the brake pads centered
and holding them still where they're not just flopping around. So what we had to
do is just bring it past that edge and then we can bring it out through this
section with a little coercion. There. Now these weren't worn out, but they were
certainly looking glazed over. Think they had so much dirt and mud crammed in
there they were actually staying again the rotor itself and causing a little bit
of a drag. So with these out, what we're going to do next is clean this up a
little bit and then put the new ones in. It's gonna be a pretty easy procedure to
do. We've got things cleaned up reasonably well, we've got our new pads,
let's go ahead and work them into position, and get this caliper
remounted. So the spring edge is actually on the inside, so we want to angle it
toward that, kicking out the bottom edge to us right now. Then we can push it
under that edge of the spring, then guide it up to get it go into position. Like
that. Okay, do it in for the other side. We're gonna actually put it in like this
with this upper edge leaning toward me and then kick in the bottom. Lift it
right there.
Alright, I've already got this one edge in, now I'm using the screwdriver just to
lift it up against the spring, and the second one I'm gonna use it to pull it
back into position. A little tricky to do, take your time. Just make sure you've got
two screwdrivers to make that happen. So she's ready to go. Let's get it mounted
back up. Next we just need to reinstall the caliper mounting bolts, and they get
torqued to 35 foot pounds. Now I'm actually going to add in a little bit of
blue loctite, that's just a personal preference. That's not required but it
makes me feel better having that little bit extra security knowing they're not
going to go anywhere. Now we're going to torque it to 35
foot-pounds.
One side down, one to go. Same procedure we just did, not a big
deal. Now I mentioned on the other side that
these were OEM pads. And this unit has a little over two thousand miles on it, so
they're probably even the originals, believe it or not. But I can tell you that
the overall shape of this machine? It has been beat on and not maintained very
well so, you want to go ahead and hit the subscribe button to where you can keep
up with everything that we're going to end up doing to this unit. I didn't point
it out on the other side but I'll say something about it now. You want to make
sure that these little boots on the sliders, they're intact: no tears and that
they're actually sealed up as they should. Because the caliper itself should
move fluidly or easily on that inner bracket or carrier, if you will. I'll show
you what I mean a couple of minutes once we get the brake pads out. They were
wearing about the same as the other side. I would have expected that. But sometimes,
I've seen them to where one side is hung up on that carrier and it'll prematurely
wear out the pads on one side more than the other. Part of a tree they got a
little too close to I guess. Now if you're going on maybe your second or
third set of brake pads, you want to definitely check the thickness of your
rotor. And I can just feel this one and tell you it's good to go. But if you're
feeling a groove at the top or especially on the inner part? It may be
time for you to put a digital micrometer on it and make sure you're within spec.
Just to show you how to check it real quick, your wear limit is at five
millimeters and I can look at that and tell you that we still have a long way
to go. Let's take a peek at it real quick. Yeah, we're 5.5 so there's still plenty
of meat left on these rotors.
This is what I was talking about earlier, where the carrier should slide easily on
the these two pins through these boots. Seen how that's so fluid? That's what we
want it to be like. If you were pulling on it and it didn't want to move or it
got caught, tries to walk one way or the other or get stuck? Then you need to go
and pull it down, take those boots off, replace them if they're broken or cut or,
you know, separated from the actual caliper or the carrier. Re-grease them
and then put it back together. Ours is still in good shape, so all we need
to do is just replace the pads like we did on the other side. And actually we'll
try it a little bit different. We'll go and put the bottom edge in and then just
lift the spring up. Pop it in. There we go. One down, one to go.
That looks like it. Let's get it bolted down. 35 foot-pounds coming up. Alright
guys. that's pretty much gonna wrap up this project. The only thing we would
have left to do is just remount the front wheels and actually torque those
lug nuts to 54 foot-pounds. Oh, one more thing: go ahead and hit your brake pedal
a few times, otherwise nothing's going to be there until those calipers close up
on those pads. Well listen, if you need any parts for your machine, why don't you come
