Brake "pulsing" Noise
I recently purchased a 2011 Buick Regal CXL with 10,000 miles on it. After driving at highway speeds (60 to 70 mph) for a bit, I get a somewhat loud "pulsing" noise when a the car decellerates from 45 mph thru 30 mph while I apply the brakes somewhat firmly. Gentle application has almost no sound thru these speeds. The local dealer service rep says this is normal. However, I test drove another similar Buick before I bought this one and there was no noise - just smooth, quiet decellerarion.
Also, every now and then, during the final stopping (5mph and below), the car may slightly pull to the right or to the left. Again, no comment from the dealer service rep.
Any suggestions?..comments? Thanks.
