Brake Pulsating
 

Just picked up an intermittant problem... the left front wheel pulsates/shudders maybe 10-15% of the time. My first thought was the rotor is warped but wouldn't it do this all the time? It does it at any speed and becomes pronounced under braking. Then, later that day, smooth as silk. Could this be the caliper get hung up instead? Looking back at my records, the rotors and brakes were done at Inspection II at 35k miles.. I'm now at 66k miles. BTW, still on the original set of tires but they will be getting changed next spring. Maybe wheel out of balance?

Wheel might be un-balanced.

An unbalanced wheel would be more noticable at speed. Your steering linkage or suspension bushings may be worn and loose. 66K on original tires? I'm impressed.

Huess I'm gonna have to suck it up and make an appointment at the stealer. They are actually pretty good... they do quality work, just hope if it is the rotor or brakes, it covered under extended maintenance.
