Hi my name's John Talley with Partzilla.com.
Today we're going to be working with the braking system on our 2007 Honda TRX400EX.
Now if you're riding along and you hear this awful grinding noise in the front of your
machine that means you probably need to take a look at your front brake pads.
What you also need to do if you want to avoid that sound is look at this little indicator
that Honda has provided.
Once it reaches on the inside of the outside of the housing that means it's probably time
to go ahead and replace them.
And as I can see, it's past the edge so that means we need to take it apart and take a
look.
So let's get started.
Alright, the first thing we need to do is go ahead and remove these two caps that cover
up the pins.
They're just held in by a flat blade screwdriver.
Not a lot of torque required on that at all.
Alright under those caps you're going to have an allen wrench; that's going to be a 5mm.
We want to loosen these both up but don't pull the pins all the way out.
Thread them back, and just let them sit just like that cause they're actually still holding
on to the pads themselves.
From this point, to make our lives a little bit easier we want to go ahead and compress
the cylinder on the caliper.
At this point we can go ahead and remove our two 12mms that are holding it to the carrier.
Once we get the carrier unbolted from the caliper we can then remove our pads.
Lift it off the disk.
And, as you can see, our pads are pretty well worn so that indicator was spot on.
A little tricky here.
You want to push in on the pads themselves because there's a spring pushing them up.
If you do that, your pins will pull right out.
And out drop the pads.
You want to be careful and not lose the shim because we need to mount that to the new brake
pads which I am about to go to the stock room and get.
Something I wanted to point out on these shims, as you can see in this diagram, is although
we have the same part number for the brake pads there's actually a separate part number
for the left and the right shims.
So be careful if you have to replace one of yours.
Alright, now let's get her put back together.
The first thing we need to do is remove that shim from our old brake pads.
Not much to it, just a small screwdriver.
Be careful not to bend it up.
Then we just want to replace it on our new pads; same position.
Make sure those holes are lined up right there.
Alright, from this point we want to go ahead and put our pins partially back into our caliper.
Don't let them protrude all the way in because you actually have to put in the pads and then
push the pins through the pads.
This can get a little tricky.
Make sure that shim faces toward the actual cylinder itself.
Put on the outer, like so.
Then you actually have to push the pads in or down on the spring while you're pushing
the pins through.
There goes one.
And there goes the other.
Go ahead and start the pins back in with your 5mm, like that.
Get both of them in there.
And at this point you can go ahead and use your flat blade screwdriver to make sure it's
all the way open.
And now we can slide it back over the disc and then put our 12mms back in, like so.
Did ya'll catch all that?
Get those snug back down.
Then we'll go in and tighten down those allens.
Don't have to get really carried away; just want them snug.
After that we'll just put on the caps and give our brake a few puts to get it to seed
in, then we can call this project done and move to the other side.
It's the same procedure over there.
And then we can take her out for a test ride.
Get the caps back on.
Now we're ready to move to the other side.
Now we've already wrapped up the other side so the only thing that's left now is to pop
on the tires and go take it for a spin.

best to answer them.
