07 maxima sl with 205k. Brake pads and rotors replaced 6 mos ago and used for a month with no problems. Left outside without use for 4 months and took it out yesterday and noticed scraping/grinding noise only at speeds below 20. At speeds above 20, no issue. Need help troubleshooting. Thank you

 

Not an issue. Car sat for 4 months and had surface rust form on rotors. Now as you drive and you brake, the surface rust will be swept away and the rubbing noise will stop. Give it some time, noise will go away.

 

Just curious. Why would it scrape only at speeds below 20, but not hard braking or high speeds. I can feel the scraping and pulsating in the pedal simultaneously. Anything related to ABS?
the noise is similar to this

At high speeds, you move too fast to hear anything

 

The problem persists after a month of driving. So, based on some troubleshooting videos, i removed the abs fuse and the sound went away. So it seems abs related. Now how do i figure out if the problem is with abs sensors or abs module. How many abs sensors are even there on this 07 maxima

 

Figured out the problem. It was the abs sensor. I suspected that. So, got an obd2 scanner and checked the wheel speed sensor readings and found the passenger sensor was erratic. It was rust. Took out the sensor, cleaned the area and now it works and no noise.
