Change your transmission fluid and diff fluid.when it gets old makes a rotor esk grinding noise

 

Tranny and diff fluid were just changed about 200 miles ago with amsoil. That had no effect on my problem.

 

Take your car out for a drive. Do some fairly aggressive braking. Then stop the car and put your hand on each wheel by the hub. If you feel one wheel hotter than the others, you know where the problem is. If it's much hotter, it is likely your brakes. Start by removing the pins and regreasing them.

 

Check the brake dust cover, make sure it's not contacting the rotors. Its easy to bend...
