Over the past couple of weeks I've developed a strange noise on my '06 RX400h. When I take my foot off the brake pedal I get a clunk, I think from my o/s/f wheel. This is followed by a noise that sounds a bit like something is rubbing. I also get the noise if I decelerate, but it disappears when I brake or apply throttle. Its just passed the MOT, but I have had a bit of a sticky foot/handbrake and wondered now if it is sticking. Is anyone able to offer any ideas as to what this may be?
