I have noticed that the brakes on my 2008 DTS pulse noticeably (not drastically) when stopping from city speeds. the feeling is exactly like that of a warped rotor.
The twist and the funny part is that after a stretch on the highway with speeds over 65mph the feeling goes away for a while and the brakes are smooth, but then after an hour or so of driving in town with stop and go driving under 45mph the pulsing feeling returns.
The good news is that I have the best dealer extended warranty program at a great dealer and I have to schedule the 75K mile checkup in the near future.
Being the hack shade tree mechanic that I am this sounds more like a wheel bearing or half-shaft/CV issue to me than an actual warped disk. What say you?
Is there anything I can do to further narrow down the symptoms so when I make the appointment I can make the mechanic's job easier or should I just tell him that I "sometimes" feel a pulsing in the brakes and it is getting more noticeable and let him figure it out without my amateur assistance?
