Remove the old front brake pads (see page 19-15 of the 2004–06 TL Service Manual). (Online, use the keyword PAD, and select Front Brake Pad Inspection and Replacement from the list.)
Do the front brake disc inspection (see page 19-17 of the service manual). (Online, use the keyword FRONT DISC, and select Front Brake Disc Inspection from the list.)
- If the disc is within service limits, go to step 3.
- If the disc is beyond the service limit, replace the disc, then go to step 4.
Refinish the brake discs using an on-car brake lathe. Refer to Service Bulletin 00-037, Brake Disc Refinishing Guidelines.
Apply a thin and even coat of Brembo brake grease to both sides of the pad shims, and the back of the new pads. Wipe any excess grease off of the pads. Contaminated brake discs or pads reduce stopping ability.

NOTE: Do not use Molykote M77.

Reinstall the calipers and the brake pads. Make sure you install the pads with the larger chamfered edge up.
Test-drive the vehicle to make sure the problem is eliminated.
