Hey guys,
1993 Toyota Aristo.
Whenever i cold start my Aristo, the accumulator motor makes a fairly loud buzzing sound as I assume that it is re-pressurizing the cylinder. Also, after applying the brakes the buzzing comes back for about 3 seconds about every 2-4 brake applications and I can hear and feel the vibrating in the pedal. I have been looking around and I am not quite sure what needs replacing. Is it the pump motor? I have also heard some mounting bushings can get worn and cause the vibration noise. If anyone has any input on how to change the motor or the level of difficulty please let me know. Any other input would be nice as well. In the video I am applying the brakes to the floor, then releasing. In one part I am quickly pumping the brakes, but not to the floor. Thanks.
