It's my '93 Previa. I changed the front tires. Still, the noise came out while I slightly put my foot on the brake pedal to slow down from
65 to 55 mph. I repeated this testing for a few times on the scored concrete lane ( i think road condition increase the viration in the front end of my Previa) in freeway. The noise sounded like lurrk! lurkk! lurkk!...(I wish I could copy the right noise similar to a sound file). Once I touched the brake peda; instantly, the noise cme out. I suspect the noise still exists on other lanes of freeway even though I can barely hear it. I'm not sure? My common sense tells me if an abnormal noise occurs it should exist all the time. Not coming out once in a while?? No viration in my steering wheel. Can a soft strut on the driver side cause this noise? Or the brake system is faulty?Any pointers and insights will be appreciated, Matt
