Thanks for the response. Is yours a constant vibration? I only feel mine by barely pressing the pedal at slow speeds and sometimes I dont feel it at all. I tried experimenting today but the wife started getting annoyed with all the stopping...lol At 1st, I thought I could feel it more when I was coming to a stop and it was down shifting but like I said its not consistent so its hard to pin point what or where. We probably are alike in that we can notice minor or sudden changes in things around us. I do have plans to take it in but always like to arm myself with any knowledge I can get here from you guys so I'm not totally blind walking in. Thanks again for the responses.
ya, mine is somewhat random. i notice it a lot when its cold outside, or even when i drive for the first time on a cold start and warm out. it might also be the simple fact that the brake fluid is thinner than usual idk. the tranny down shifts differently to accommodate the road conditions, whether it be uphill, down hill, or flat. when i brake and it downshifts on flat road is usually when i notice it the most.....btw this is just me being EXTREMELY ocd. i usually ignore things as much as possible or ill dive myself nuts.
brakes are never going to be 100% smooth as it is a frictional operation. by gently putting your foot on the brake its prob going to be worse than normal. your not applying as much pressure which i can only assume is going to cause the pads to skip a little. i personally think it is a mix of driveline frequencies (as there are many in the Titan) and maybe slight imperfections in the pads, rotors, or fluid thickness. it could very well be warped rotors, or at least the start of. usually that will result in a slight steering wheel shake as well though. good luck and let me know if there is an issue
