Squealing and rubbing noise while turning after replacing ..

Like I said earlier.. I did not change my pads...so I did not
dismantle my caliper...Should the slider pin be lubricated when you
change the rotor? I did not want to mess with the caliper...so left it
in place..
Also, I have noticed that the noise (squealing on the right and
rubbing on the left) went away when I applied my brakes.But I hear -
the squeal even with a slightest turn to the right (like while
changing lanes) and the rubbing noise on left when I make a sharp
turn. Anything else you can think of?

Thanks

You may have forgotten to check and _lubricate_ the slider pins that
allow the caliper to 'float' as the pads slowly wear down. See all the
helpful stuff about brakes at www.tegger.com

Oh, the joys of aftermarket parts.

Sounds like the rotors may be too big in diameter and are contacting the
pad slide shims or the mount bracket. Check the rotors' perimeters for
signs of polishing and scraping.

Aha! A new development. When you say it fit "snugly on the screws", you
must mean the holes in the rotor did not line up with the wheel lug bolts.
That's very bad. And VERY aftermarket.

Are you sure the rotor is actually, really and truly, FULLY seated on the
hub flange? It should clang home when you install it.

Mike the rotor "top hat" thickness while it's off the car. Install the disc
again all the way as far as it will go, put the Phillips screws back, then
mike the clearance from "top hat" face through a hole to the hub face. Are
the two measurements identical? Might be tough to measure this for lack of
clearance.

Mike the diameter of the inside of the rotor where it mates with the hub,
then mike the hub diameter. The hub diameter should be ever so slightly
smaller. If the rotor is smaller than the hub (even by a few thou), the
rotor won't fit properly.

Is the rotor's center hole bigger or smaller than the hub's center lip? Is
there a chamfer on the inside of the rotor's center hole where it mates
with the radius on the hub lip?

A non-fully seated disc (or a wheel with rust on it) will cause slight
movement while cornering that may be heard as noise at the wheels.

An idea!

Put the rotor back turned 90 degrees from the position where the Phillips
holes line up. You can't put the small screws back that way, but you can
use the lug nuts (finger-tight) to hold the rotor in place. Now you can
mike the above-mentioned dimension.

....using the screw holes in the rotor. Forgot to specify that.

OK will try that today evening and let you know. Thanks a lot Tegger.
You rock!

I forgot to mention...I have the Brembo four piston caliper in the
front..

Weird! I have to tell you...my powersteering oil hose was leaking and
since i had warranty i went to the dealer to fix it. I spoke to him
about the rotor noise also and I told him that I put the powerslot
premium rotors..he looked at it and said that they are not the right
rotors for my car...and the most weird thing is that he claims my car
is a type S. I bought this car from a private party and as per the
previous owner and other docs...it is a regular 2004 3.2 TL with 6
speed manual. The mechanic says that 2004 6 speed are considered type
S and they carry thinner rotors. I have never heard abt that...is the
dealer trying to trick me? do you know? please help me..

Check the VIN with Carfax;it will tell you if the car is truly a type S.
Or call a different dealer.

If you jack the wheel just off the ground, can you very easily spin it by
hand, and does it keep spinning for a bit after you stop pushing?

Oh man!!! i jacked my car up and spinned it...it did not spin freely
and I touched the inner side of the rotor....it was so very
damaged...had a gutter that ran all around the rotor which was abt
half a centimeter deep..thak got it did not damage my brembo
calipers...i finally removed them and replaced my old rotors..which
are still pretty good....but am getting brembo blanks now..

Powerslot does not carry rotors for AcuraTLs with brembo 4 piston
calipers...

Thanks all for helping me out...Thanks Tegger!

Nashbk,

Let me tell you something: you will not experience any better performance
from those aftermarket components than you would from the factory parts.

Aftermarket /looks/ cool (way cooler than OEM), especially through your
open-spoke wheels, but in the long run you will not be happy with their
function.

If you had a deep groove in the new rotors even with your low mileage,
something was dreadfully, horribly wrong. Dump the aftermarket stuff and
put the factory stuff back on. That includes those 4-pot calipers and their
mounts...
