Ok,,Brakes on my 03 Deville shimmy on slowing down. I replaced pads and rotors(had 81,000 miles on them). Still did it. Had tires balanced. Was not as bad but still does it on slowing down. Are bushings bad or what? Bought the car used,no car fax damage reported. Drove fine untill 3 -4 months ago.These should be smooth on braking.

 

Try slowing down with the parking brake! By that , I mean coming to a very slow stop, depress the parking brake to see if the pulsation is from the rear, not the front.

 

Could it be a bad tire?

 

I doubt it. A tire will shimmy whether you apply the brakes or not.

 

brake shimmy is caused by warped rear rotors, warped front rotors will manifest in a steering shimmy

 

OK,,On applying the parking brake it did "shake" some,,,I replaced the pads(had about 2 US quarters thickness left). Helped some,,still does it. I think tie rod ends(inner or outer)???

 

I guess you are bound and determined to do what you want? Resurface the rear rotors just before you change tie rods. Then report back.

 

i know you said that you replaced the rotors .. but going by what has been reported,
something is wrong back there in the rotor dept. maybe new rotors were warped or
got warped?

IF it is pulsating or shimmy, it has to be caused by a rotating component. no?

 

i think steering shimmy plus brake pedal pulsations ?

 

He never said 4 rotors, so I assumed only the front 2 were replaced?
