Ok. I had my brake pads replaced nearly (2) months ago due to excessive squeaking. In the laast couple of weeks, I noticed that when I turned the wheel and braked at the same time, I would hear a grinding noise. Last evening, while traveling home from work, I noticed that the "TPS" check light came on and nown when braking, I hear a gridning noise following with several "pops" and "clunks". The earliest appt my Lexus dealer has is tomorrow at 11:30. No loaners are avail...

 

Have you checked the brakes for obvious problems, like a pebble caught in the caliper, or a deep groove in the rotor from a pad rivet? You may be able to see something obvious without even removing the wheels.

In any case, probably not a good idea to drive the car in this condition.

 

Sorry for the obvious but have you checked the tire pressure?

 

Did take a visual of the rotors and checked the air pressure. I even went as far as adding air to the tires (after it was sitting overnite) with a compressor pump and reset the tire pressure - no change. They were nice enough to call me in - had a loaner avail - a 2006 Altima w/ 100 miles on it. Boy...is this car loud. Sound like a damn 1994 Dodge Neon....

 

Please let us know what they find.

 

Sounds like a caliper/brakepad issue. Let us know how it goes.
