I have a 2001 GMC Yukon XL. It has around 73K miles on it. The brakes squeak almost every time they are applied. I have had them checked at 2 different places and my husband even looked at the pads with the mechanics, who both told him that they brake pads and rotors were fine, and did not need replacing. Is there anything else this could be, or just a chronic thing I should learn to live with? Thank you.
