I love my 2012 RX350, but I hate the front brakes - they seem to last one or two years and then they start pulsing. I am a careful relaxed driver and seldom do anything close to an emergency stop. I bought the car with 33,000 miles and replaced the front pads and rotors with Lexus original parts at at around 53,000 miles. These pads and rotors lasted about 2 years before they started pulsing at around 75,000 miles and then I replaced them with Powerstop Evolution pads and drilled and slotted rotors which I bedded in carefully as per the instructions. They worked well for a while, but only lasted one year and approx 15,000 miles. I've now bought Wagner rotors and Brembo pads which I'll change in the next few weeks. Any ideas when the brakes need replacing so frequently? Thanks.
