Changed Front Brake Pads - tic tic tic....

[DOCTORBILL]

I recently changed my front disk brake pads for new ones.

The pads were exactly like the old ones.

The rotor looked like brand new! I didn't have it turned as I could not
see any wear. No ridge evident on the edge of the rotor.

Now the front end tics often - not always! Turning sometimes makes
it go away. The brakes work fine - no binding. The car rolls freely.

What could be going "tic tic tic" (varies with speed - so its the rotor)
if nothing was binding up - I checked before putting the tire back on.

Wouldn't anything striking the wheel or rotor wear off rather quickly
and this ticking go away!?

I had a Jeep Cherokee do this and I could never figure out what was
doing the ticking....

Could it be a noisy Constant Velocity knuckle? Will it do it when you jack it up and spin the tire?

take hub cab or trim ring off, sometimes they will make noise. see if noise goes away

Can't be the hubcaps because I haven't put them back on the front
wheels yet.....

These are just purchased wheels just for the snow tires.
I hope the wrecking yard I bought them at didn't sell me an "off"
size wheel, too!

I'm wondering if just the slightest "nub" on the outer portion of the
rotor might be slapping one of the disk pads. (?)

I thought maybe I should take my rotary grinder and just barely
grind off the very outer portion of the rotor where the disks ride
in place of having essentially new rotors turned. A waste of good rotor
metal to have them turned. They don't brake with any shaking, so they
are not unevenly worn as can happen.

It MUST be something striking the wheel.

If I weren't a chicken sh*t, I'd jack up the front end, take off both
wheels, put it in gear and go listen to the turning rotors....w/o
wheels on it ! Scares me though.

WHEELS or ROTORS....(?)

if you block car up carefully with e brake one should be safe to run it with wheels in the air, just don't try and do 70

There is half a foot of snow on the ground, it is about 16 degrees F
and I am still uncomfortable doing that.

In any case, what might it be from?
And since I've been driving w/o any ill effects, it can probably wait
until Spring - no?

if you know what side noise is from might take wheel off and look inside rim for shiny spot like something was rubbing and check out rotor and other parts, make sure everything is tight, turn rotor by hand and see if you can hear the noise. its cold too here with snow
