Hi, This happened to me , i was able to solve it. I had a pulsating sound in the rear left side when i break softly. It happened sporadically in corners and on higher speed. I had the front control arm replaced and it helped by stopping the high speed pulsation , but it continued in the rear back left wheel. even sounded like bad struts when i went over bumps. i had all 4 rotors and breaks replaced, and problem continued, I replaced 2 rear struts and problem continued, finally double checking the rear tire while the car was elevated I grabbed the tire on the right and left and pushed hard to the right and left of the tire and mechanic could see that it was the suspension rear arm assembly ( control arm ) the bushings where bad and that solved the problem. PS - my car is a lexus rx 300 2003 FWD, and autopart part did not work because they all where 4WD 1/2 inch larger - so i had to buy part from Lexus, or get part number and buy from ebay. see attached pictures
