Lately I've noticed my truck makes this weird noise. Sometime's it's when I have the brake applied, sometimes not. It sounds like a whistle almost, or a squeak with air. That's the best way I can describe it. Anyone else have something familiar? Or have any ideas?

 

Yes, i've been having the same.
Going to take the truck back to Hibdon in a few days.

 

Did you get recent work done on yours? I changed my pads last winter, the sound just came up.

 

Yeah, new rotor and new pads aprx. a month or two ago.
